 Getting ready to plug in my BK-16's for break in. I have never heard a single driver speaker before. What should I expect? Why do people either love them or hate them? I have never seen a in between opinion. Some love them, some hate them. Why?

 You will probably find their (BK-16) sound to be sublime on certain types of music, and somewhat lacking on others.

I have a couple different single driver speakers and they are superb on simple music like Marc Cohn, Cat Stevens, David Sanborn, Sting, or bluegrass etc.....Their sense of acoustic space is uncanny.

They are not my transducer of choice for large scale symphony or electric rock such as Rush, Van Halen, Def Leppard, Metallica etc....

You may find them a little tipped up in the upper midrange - or not. Many owners end up with adding super tweeters and subwoofers which in my opinion defeats the purpose of owning a single driver speaker to begin with.

In my opinion speakers are to audiophiles what guitars are to accomplished guitar players. Could you imagine Jimmy Page, Steve Miller, Alex Lifeson, or Eddie an Halen with only one guitar?

I have a friend that purchased the BK-16's from Madisound several years ago that I have heard many times. Those speakers are very nice, just don't expect them to do the impossible. Also; If you initially do not find them to your liking, don't give up, as you may have to try different amplification - A sterile sounding cheap solid state receiver is probably not going to make a good running mate.

Let us know how things turn out.

 Adding a sub and a super tweeter isnt all that bad. You can use them at just the extremes, which leaves most of the spectrum still covered by a single driver. Cross the subs at about 100, and the super tweeters at 10k or above, and you still have the important midrange well within a single drivers range. Add a series cap (or adjust the value of the one that is most likely already at the input) to the input of your amp driving the single driver to remove the bass below 100, and it will clean up the midrange a lot (you will need a signal generator and scope to do this best. If you dont have these tools, you can probably find someone near that does). This will give you the extension of a multi driver loudspeaker with little or no impact on most of the range.

 If you use a large full range driver, they often need support in the upper frequencies.
If you use a small full range driver, they often need support in the lower frequencies.
I've found....through trial-and-error....that a 6 1/2" full range driver is a pretty decent compromise.
6 1/2" will do a pretty good job at the frequency extremes, generally without addition drivers.
Well, unless you are a total bass freak, then get a subwoofer.

 Some years ago I heard Lowther loaded TP-1 at home of no lesser than Frank Reps. Jazz sounded eerily life like but big orchestral works somewhat lacked the dynamics of a 3-way system. I eventually built an 80Hz single driver horn with Fostex 206 ESR. Again, it sounded great but for somewhat compromised bass. My two bits.

I concur with your assessment.

If low or high frequency help is used at the outer reaches of the bass and treble and the full ranger is doing 90% of the lifting by covering 100 to 8khz, then they are still full rangers in my book.

I built these "full range" PAWO side horns with Merrill DCA drivers for my sister about five years ago. While the sound very good on their own, they really shine with the dual subs crossed over at around 95hz.
The system looks a bit disheveled because she set up a gaming console for my son to play with while we visited.

 I am building sub woofers for them. I have been listening to a lot of jazz lately. Gypsy Jazz and Swing. But I prefer the smaller Swing Bands rather then the large Orchestra's. I have a pair of Audio Concept Sapphire II T's with a pair of Sub Ones, with a push pull KT88 amp in my office system. For the BK-16's I just built a Tubelab S.E. 300B amp.

 Haven't hooked them up yet. Its been windy lately. I'm waiting for a calm day to take them outside to photograph in the sun. Then into the garage to break in for a while before I move them inside. I have some work to do in the den before they go in there. I doubled the thickness of the sides and top and bottom. Filled the two hollows with lead bird shot. And veneered them with Etimoe veneer on the outside. It looks like very curly walnut, but the curl has some great coyancy. The front is quilted maple and the horn is curly maple. I'll post pictures when I take them. I also just built a 300B S.E. amp which needs some break in also. The Psvane treasure MKII tubes say they need 400 hours. So I'd like to get one or two hundred hours on them while I'm doing the work in the den.

 You may or may not like the tone of the Fostex. Some of 'em are just... very... aggressive. Some are more benign.

.. and of course the Fostex drivers are notorious for long break in times (i.e., don't jump to conclusions).

Empathetic amplification will be important -- what are you planning to use amp-wise?

You (the OP, that is) might find this current thread on the Polk forums on roughly the same subject. I apologize in advance that I, not uncharacteristically, have kind of dominated that thread :-P

 I've been using Sachiko double-back-loaded horns with various 8" "full-range" drivers for the past eight years. After years of listening to the same speakers on the same system and in the same room here's the conclusions I've reached:

1) No single "full-range" driver truly exists. At best you'll find some very nice extremely "wide-range" drivers!

2) Find the best extremely "wide-range" drivers you can ---{I really like the $256/pr Dayton PS220-8 drivers with Rispoli-modified cones}--- and add a woofer from somewhere between 50Hz to 80Hz and a tweeter from 8Khz to 10Khz, while running the extremely "wide-range" drivers full-range.

Following those two steps will give you the best of both worlds. By running the extremely "wide-range" drivers full-range, you'll get the sound that people use supposedly "full-range" drivers for! While adding a woofer somewhere between 50Hz to 80Hz and a tweeter from 8Khz to 10Khz, will fill in the two frequency extremes where the extremely "wide-range" drivers start to peter out. This is what I've done for most of the past 8 years and have been quite happy with what I've been listening to...

and I will offer a not entirely cogent thought along the lines of the "augmented 'fullrange' driver" concept as Tom presented it.

Way back when, good ol' Electrovoice (who were long-time purveyors of 'fullrange' drivers) sold a line of consumer loudpeakers which used a good 8" twincone driver as an extended midrange reproducer, augmented with a woofer and a tweeter. There were several models. I happen to have a pair of the 'entry level' model, the Esquire -- and I find them quite successful. The Esquire used EV's entry level "Wolverine" LS-8 AlNiCo twincone FR driver for midrange. The better loudspeakers in the line used the better EV SP8B for midrange, bigger woofers and larger boxes.

Indeed, I like to say that the EV Esquire what the Klipsch Heresy could have (and, I would argue, should have) been. Without that sqwanky ;-) resonant MR horn, these don't manifest that ear-gouging aggressiveness of the Heresy -- even though the woofer & tweeter used in the Esquire aren't all that different than the EV drivers used in early Heresy loudspeakers. Indeed, the Heresy used the EV T-35 tweeter for years and years for treble (and, I'd opine, not to terribly good effect).

It's probably worth mentioning that a later version of the "Esquire" speakers used a very different MR (ca. 5" cone in an 8", closed-back basket) than the LS-8 shown & discussed here. I cannot vouch for that MR driver (save to comment that it was much less visibly impressive).
Oh, and (also FWIW): I tend to use the term "extended range driver" in lieu of "fullrange driver"... same idea as Tom's nomenclature.

EV Esquire au naturel

 I have had a few different full range single range driver speakers over the years, and listened to many others. I have owned 3 types of Omega's (all with subs), Lowther Medallion II's, and my current speaker Shelby+Kroll monitors which are a full range driver with a tweeter that comes in above our hearing level. Some that I have listened to are Musical Affairs, Cardersound Sachiko, and Carfrae Little Big Horns.

All of the above, except Musical Affairs, were augmented with either a tweeter or subs. Which to me begs the question; Are they really Full Range Single Range Driver speakers? By definition a FRSD speaker should contain only 1 driver!

I recently had the pleasure of listening to Charney Audio Full Range Single Driver rear loaded horns based on the Traktrix Theory. I was gobsmacked at what I was hearing and not hearing. I heard deep clean bass with no sub! An engaging midrange that drew you into the music like a sultry siren. Sweet and extended highs with a deep and spacious soundstage! What I didn't hear was limited range with compressed break up at higher volumes.

Fit and finish are impeccable and eye pleasing works of art. If your near Somerset NJ which is about an hour from NYC, and 1.5 hours from Philadelphia, make an appointment and stop by for a listen. Brian is very hospitable and will answer questions you might have about his creations.

 I very much agree with others who have already posted to this thread. The best sounding way to use allegedly full range drivers is to instead use them as wide range drivers. I've used Lowther PM4s briefly and then much better AER MD3s. I never even considered settling for the limited frequency response of which they were capable. Instead I expected and found that using them as very wide range drivers (160-200Hz to 8 kHz) drivers with excellent woofers below and super tweeters above (in my case Fitzmaurice HT Tuba corner horn subs and Fostex t900a bullet tweeters above) took best advantage of what supposededly full range drivers can do very very well which is to allow most of the spectrum of music to be reproduced without crossover points.
I dream of an America where a chicken can cross the road without having it's motives questioned.

 That really is the best use of a full-range driver--as an extremely wideband midrange driver. My all-time favorite is a Jensen M10 used as a bass/midrange driver with a bandpass protected tweeter coming in way on top. The 13" Jensen is run full range, but, it of course cannot really do the extreme top end and the dispersion pattern becomes way too narrow because of the large diameter of the cone. I suppose a bass nut would use a woofer down below as well, but, this driver is surprisingly capable, even when used in an open baffle.

I don't, myself, know of a full-range driver (electrostatic drivers excepted) that really could deliver the goods. The closest I have heard is the field-coil Feastrix, and the old Western Electric 756 (definitely not the more common 755).

 Well, I bet they do sound nice. However, for a fraction of the price, a simpler full range with a sealed sub and super tweeter used at the extremes will probably sound more satisfying. Removing the last bass octave or two from the full range driver will lower midrange distortion noticeably. A 3 way 'full range' system will do it all, from small groups to full scale symphonic music. Just my opinion of course, but I have experimented with this a fair amount. One good thing, you can try it and always go back to full range if you prefer. I bet you wont.

 Just hooked up the BK-16's with Fostex FE166en speakers. They don't sound bad right out of the box. More bass then I thought. And my tubes aren't very good in the bass department yet. I'm powering the BK-16's with a newly built TubeLab Single End 300B amp. All the parts in the amp need to break in also. I replaced the electrolytic caps in the power supply with Mundorf Poly tube caps. So I'm sure they all need to break in. And my Psvane Treasure MKII 300B tubes only have 14 hours on them. I read that the bass and treble from these tube will bloom sometime over the next 300 hours. So they are in the garage playing now. I go in every so often to check on things. So far so good. They claim the FE166en's don't need a super tweeter. We will see. I am building sub woofers for them. I let you all know how things progress.

 geezerrocket...I listened to the Maestro and Concerto at different listening sessions. The Maestro is a very good sounding horn that gets it right. We put on a number of different tracks and I measured audible bass to 32hz with a test tone. We put Billy Holiday Lady In Satin in the stock Oppo bd95 and whoa! Every nuance of her well worn bluesy voice came through. I found myself leaning forward so I could touch her. I kept shaking my head in amazement and kept asking " how do you get that kind of engaging sound and deep bass from a 6.5" driver?"
The gear was Charney's 300b amp, stock Oppo BDP 95 with variable out for volume control, a noname IC and lamp cord for speaker wire. I couldn't stop shaking my head in disbelief but believed what I was hearing for sure!

Will post about the Concerto next...gotta run out.

 I didn't go the route of Single driver + high and low range drivers. I bought a speaker from Tonian Acoustics with a single driver crossed over to a reworked (by Tonian) ribbon tweeter. This combination eliminates the jagged roll off of the single driver. The bass is fine for my preferred music and untreated, odd shaped, small listening space.

 You can often avoid the super tweeter, as I have heard single drivers with decent enough high end, but I find adding a sub is always beneficial. Be sure to limit the low end of the single driver to clean up the midrange. This is easily done by just reducing the value of a coupling cap that most likely is already in the chain somewhere. Select a value to give you -3db at the upper limit of your sub. To do this properly, you need to use a signal generator and a scope (or multimeter), so you can see the -3db point. Keep adjusting the value of the cap until the right value is found.

When adding a sub+tweeter, does one need to have specific crossover points so that the full-ranger handles orchestral music properly?
Or
Is one doomed with a full-range driver on orchestral music with or with out the sub+tweeter?

 I would not own a pair of true single-driver speakers. Most of them are of the *one trick pony* variety, whereas I need a sturdy and versatile saddle horse.

I would, however, own a pair of Royal Device Laura Studio MKII single driver speakers that are "augmented" for near full range performance. And in fact I do own a pair of these.

 I have some Norelco 6.5" full-range drivers if factory cabinet. I was surprised how good they sounded when I tested them to see if they were working. I should try them with my subwoofer. I believe the Norelco drivers are the Phillips.

 The OP was asking about Single drivers...not 3 way designs. I get your point that you could build an OK sounding speaker using a "full range" driver and augmenting the bass and highs for less money. I'm offering up my experience of a single driver horn that is very meticulously built and sounds waaaay better than it should! No crossover, no sub, and no tweeter!

The biggest problems with mostly all single driver designs is the enclosure and how it reacts with the room. Charney designed his horns on the Tractrix Theory and the result is phenomenal. The rear loaded horn seems to "couple" with the room. I listened to them at Charneys 14x19x9 room and at a nearby customers (friend of Charney) room that is a narrow attic room with sloped left and right walls that went from 4' to 8' and about 13'w and 15'l. Both rooms sounded fantastic with very good bass and only small panels for the first reflection point.

BTW: My Maestros will be ready in late May.

 I loved them as mentioned for certain music. Jazz, Blues, small rock bands, No big orchestra.

I used the Fostex 166 in the Fostex Designed BLH box I built. Not the BK 16 boxes.

I also had what I think were quality components.
Empire or Thorens TT
Rogue Tube Phono preamp
Fi X with magnaquest transformers (Used Both 2a3 and 45 Tube)
Bottlehead Foreplay III preamp
Bottlehead Paramore II's with 2a3 tube

Music just hung in the air, bass was much more than I expected.

I regret selling all that equipment!!!

 Even though its a 2way its still a single driver mount. The Altec 604E 30 to 20k at 98db efficiency

And the Fostex FE208esr or 208ez. I think they are 40 to 20K at 96db. Not quite full range but in a BLH against a corner in the correct factory cabinet, ,they would be pretty close.

I find that a critical component to delivering a coherent wavefront is consistent directivity across the bandwidth.

With the high xover frequency for a 15" driver, there's an octave at the very heart of the midrange that will be inconsistent with what's below and what's above.

 They have two problems: Poor bass, and poor highs.

I *get* the idea of no crossover through most of the audio range, and that's a good and attainable goal. But you're NOT going to get good bass and good high end from a single driver.

A 3-way is the minimum for a high quality speaker.

 The high frequency irregularities in all of the single driver speakers I have heard pushed me away from ever buying a pair.

Now, if you want a truly full range single driver speaker, pick up a pair of old Acoustats!

 i can't particularly say i hate single driver speakers as i have only limited experience with lofi systems, but can't picture getting truly worked up about them as even soft dome tweeters are too mushy on metallic percussion for me where i prefer a good aluminum or titanium tweeter. percussion is very important to me and probably why i like sealed speakers better.

that's my 1 and a half nonsense

 Hello genungo!

I used to own a pair of Aliante Pininfarina Ones, that are owned by Royal Device, that I felt were a wonderful sounding pair of 88dB 2-way, stand-mounted speakers! However when I decided to switch to using Sachiko, double-back-loaded, horns with high sensitivity "wide-range" drivers, I did just as Roberto Delle Curti did! Although I obviously used different drivers than Roberto did ---{I ran a pair of Dayton $256/pr., PS220-8 drivers with Rispoli treated cones}--- I ran the "wide-range" drivers full-range and just like Roberto in order to augment and extend the high frequency response of the PS220-8 drivers, I crossed in a pair of Fostex T900a horns at 9Khz via a single cap. This effectively extended the PS220-8 drivers from about 10Khz, where they started to roll-off, out to 40Khz, and quite nicely indeed.

Believe it or not the $256/pr. Dayton drivers, once their cones were treated by Mr. Rispoli, sonically bettered Lowther DX4, and Fostex 200a, FE206E, FE206ES-R and FE208ES-R drivers. Being much clearer, with better micro-detail, smoother and best of all, these PS200-8 drivers once their cones were treated, could easily play over 100dB without breaking up! For the very first time, in my experience, I could now use single, wide-range drivers, to play Prog-rock at volumes loud enough to chase you from the room ---{due to the sheer loudness}--- without any break-up, strain or distortion!

Let me tell you how amazing it is to hear all the sonic traits people listen to "full-range" drivers for, when playing Prog-rock by Yes, early Genesis, Camel, Starcastle etc., at 100db+! This is an entirely new experience that simply has to be heard to be believed. Even from the adjoining room ---{which is where you have to listen when music is played at 100dB+ volumes, "if" you wish to keep your hearing}--- it's like hearing a pair of Quads with better high frequency extension that can play at 100dB+ volumes. Cross in a pair of nice, high-sensitivity woofers somewhere between 80Hz to 100Hz and it's a really amazing pair of speakers indeed, and they can be made at a very reasonable cost too!

I'm listening to: Across The Rubicon by Silhouette

 Ok, I have my two bucket subs built and hooked up. They blend seamlessly with the BK-16's. I have them hooked up using a Y cable from my speaker binding post on my Tube Lab 300B amp, through 600 ohm resistors to the line level input on my Crown XLS 1500 amp. Crossover set at 56Hz low pass. Volume at about 12 o'clock. I'm running the amp in bridged Mono, into the two subs in parallel, for 4 ohms, and 1550 watts from the amp. I put on Reference Recordings, Virgil Fox, The Bach Gamut.
That organ hits some low notes. And the buckets reproduce them effortlessly. And they will sound even better when they loosen up a bit. But for now I am a happy camper.

 Hi Anthony R. Guarnera,

I apologize for going off the thread topic. I'm not being critical, but I'm a word junkie and I haven't been able to find a definition for the word coyancy after doling a Google search and checking 1,065 English language dictionaries (Alpha Dictionary). I am guessing it is a foreign language word. I would truly appreciate it if you would tell me what coyancy means.
I dream of an America where a chicken can cross the road without having it's motives questioned.

 I hope I'm not off base in suggesting that Mr. Guarnera may have meant the following word:

Chatoyancy

From Wikipedia - Chatoyancy in woodworking occurs where certain finishes cause the wood grain to achieve a striking three-dimensional appearance, also referred to as "pop-the-grain", "wood iridescence", "moire", "vibrancy", "shimmer" or "glow". This highly sought-after effect is sometimes called "wet look", since wetting wood with water often displays the chatoyancy, albeit only until the wood dries. Oil finishes, epoxy, and shellac can strongly bring out the "wet look" effect.

If I am wrong then my sincere apologies

 Leadfoot,
Thank you very much. That is what I meant. My spelling is really bad. I thank you very much for correcting me.

 Hello, i am professional speakers designer from Bache audio
My latest model 002AB is based on full Range Driver which i used like
widerange driver, , my Conclusion based on long time experimentation

Just adding Supertweeter and Sub is not enough to made this system working fine. First problem- all full range driver get bad ability reproduce
not just lower base and also midbase make sound Thin.
second big problem -- big step coming up from 3000HZ up to about 10DB
make sound HORNING they need serious flattering using Professional measuring tools
