Yes , they are pretty. Custom built by master carpenter in oiled walnut , double walled baltic birch . I'm not tearing them appart. They will stay intact I just pull the horn and put round baffle with 10" Tannoy driver instead. Kevin made them to look like Tannoys so let put at least one Tannoy in. They don't sound that bad just little confused and are beaming rather badly ;)In our present living room I effectively hear only 1 speaker . I think I start collecting walnut boards to turn shallow horn adapters for those 10" golds and match that look. I will be back in MI middle of Nov. and than I'll stop by.
PS. I need one NOS 10" gold , or one used 10" gold regular small square basket or one oversized 10 " gold with square 12" basket. Somehow I ended up with three orphans and need a match :)

Thanks Mats
The idea of 10" golds came to me after I noticed that behind the horn is enclosed and sturdy 2-3 Cu ft compartment , perfect for 10". I will cross around 70-90 hz and will run SET on BASS and PP on Golds as I always wanted to. Friend of Kevin said he had to import original Tannoy dust cloth material for covers and it costed an arm and leg;).Each speakers weights a ton (350 Lbs or so. In present incartation it sounds little confused and beaming but for TD4001 in tantrix horn suprisingly non offensive (unlike in only slightly smaller 340hz Edgarhorn where it was unbearable. Final system would be those ,Klipshorn wih altec driver as midbass from 50- 160 Hz, TM 1201 in 150hz Trax , td 4001 in 270hz trax ,td2001 in 1000Hz lecleach and et703 in 2000 le cleach. I only need Adams family castle in the suburbs and I'm set :) Rgrds, W

Anyway I don't think the system will ever come into fruitiion considering the space requirements:)

"I'm surprized at how little tow in is used in these systems"

Pooge,
My "Kitchen Sink" cabinets are flat against the wall with a built in 20 degree cabinet toe in, which puts the center of the coverage pattern 12 feet back, with a listening area about 50 feet deep.

Rkeman's speakers appear to be toed in at 45 degrees, half the nominal coverage angle.

Many of the other more "beamy" horns appear pointed directly at the "sweet spot".

Other than a few cabinets which appear to be flat fronted (probably for aesthetic, rather than acoustic reasons) most appear to have toe in correct for the room and presumed listening distance.

JoshK,

I use an active Marchand crossover at 500Hz for the woofer to mid horn. Tried 600Hz also and honestly could not tell the difference.

I have a passive 1st order filter for mid to tweeter at 10kHz with 0.13 mHy and 2.0 uF cap. This crossover point was chosen only because I had those value components on hand and it sounds very nice. I'm sure there is room for optimization at a later time. I also tried running the mid horn full up high and rolling in the tweeter at 13.2kHz with a 1.5 uF cap. I can live with it either way. It gets hard for me to judge small changes. I run both the mid and high drivers without any attenuation. They sound well balanced to me.

Good luck with your project. What CD will you use on the Iwata horn?

Thanks for the info. I have measurement gear, so I'll likely take a stab at the whole design, but I thought I'd do a mock up quickly first to get a taste.

I will be using Radian 950B drivers with the stock diaphragms at least to start. TrueExtent could be an option, but over the range intended don't know if they are worthwhile.

I have a slightly older pair of Fostex bullets meant to load down as far at 5khz, but the 500AM-MKIIs are an option I've been considering as well. Will start with what I got first though.

Hi Guys,

Both these implementations look very nice; I imagine they sound wonderful. At first glance I thought these wre the AutoTech E-JMLC-300, but I now see they they are quite different.

This is a little off-topic, but here goes. Some time into the future I'd like to experiment with a pair of the ~300hz horns; are you able to briefly explain why I might choose and Iwata in preference to the JMLC, or vice versa? I will also do some searches on the Iwata.

Thanks.

Pro Sound Guy

If you placed an absorbent panel or a diffracting panel to the left of
the left speaker about where the outlet is and coming forward a few feet
you would stop that nasty reflection off that left wall that is more
then likely smearing your image pretty badly.
Get something a few feet wide and the height of your tweeter.
:)
If you want to test it simply try a polyester blanket pinned to that spot
and hear the difference for yourself.
You have open space to the right of the right horn and that is what
you want to recreate on that left wall with room treatment.

The "Kitchen Sink" deck speakers used up most of the drivers I had scrounged from various partly blown abandoned stereo speakers, each contain three tweeters, two 3" mids, and two bass reflex 10" lows.
The tweeters are physically time aligned, output is complimentary and coherent in the far field to 16,000 Hz.
Two layers of grill cloth and Duratex paint make them weather proof.

The tapped horn "Tub Sub" uses two $5 buyout 10" speakers, is 99 dB one watt one meter in half space at 60 Hz (open field) but located against the wall behind the hot tub, 24 Hz is only 3 dB down from 60 Hz, with a "loudness contour" peak at 40 Hz.

My one regret was padding down the mids and highs, not anticipating the sub would become so much more sensitive against the wall, and add in the frequency range of the pair of dual 10”, as it is on a receiver sub out that goes upwards of 250 Hz.

We usually listen at low levels outside, so having the big bottom is nice, though the indoor speakers are a bit too bright by comparison to the deck speakers. That said, the sound is pretty consistent walking from the living room through the kitchen and outside, even though all the speakers run from the same Technics receiver.

My listening seats (as you can see in the images gallery) are slightly tall. I wanted to get the drivers at about ear level, especially since the Canterburys are toed off-axis between 14 & 15 degrees already.

Also wanted it to sound even more open and alive, both of which happened.

Didn't love the Tannoy feet either, though they aren't bad at all.

The stands are nothing special, except they get out of the way of the music.

Two horizontal 4x4s joined together. The black vertical frame simply sits around the horizontal 4x4s to hide their appearance. Doesn't actually touch them.

The Tannoys are on Grand Prix Audio Apex footers, which includes the GPA silicon nitride balls with levelers.

The 4x4s are on Herbie's decoupling footers. As might be obvious, I'm not a fan of spikes for any audio application.

Best regards,

Jim Smith

The sub is truly unique: 1" plywood beautifully finished in golden oak. All inside cavities are covered with automobile underbody cover stuff. It houses one 18" JBL driver. A true 35Hz with a lot of residual output. The bottom exhaust can be separated from the body for transportation. $2000 or PC based music server a la Mac Mini with all the bells and whistles, or similar...I'm in LA and you are welcome to stop by any time. BTW, I built a similar sub for Cy Brenneman (of Brenneman Audio) You can contact him and get his impressions.

They're 1 piece SP-1s. They're a relatively early pair and they have the original CTS woofers with the square magnets. They really don't have much output below 80 Hz, but I have a really serious subwoofer system to compensate. I recapped the crossovers. I still have the original 22 square magnet horn drivers, but I've decided the 22a round drivers sound better. I also tried the 22XT+ titanium diaphragms, but have gone back to the aluminum which seems to sound a little smoother. I might try the current RX22s at some point if I get ambitious. More likely, I'll eventually go try something from Danley and end up selling these.

Thanks for the information. Interesting to hear your thoughts on the square Vs the round 22A drivers as well as the new Ti diaphragms. I was disappointed to see that the new Ti diaphragms were not also one piece former and diaphragm and that they did not have the Mylar suspension any longer. I am using 20 ppi foam damping in the throat of the 22A comp driver to good effect. You might just get some ferrofluid and experiment with that if you like. The new RX22 use fluid but I don't know if they have a different style phase plug which might be a benefit as well. Thanks to the response. Best regards Moray James.

The RX22 has something that looks like pie pieces. I have a pair in some SP3s that I actually user for sound reinforcement. I just have to decide I want to bother with taking them apart and trying out the drivers in the SP1s.

Wow live and learn. Thanks for this most interesting information. I have both square 22A and round 22A I never compared them and always assumed they likely had identical phase plugs. my round magnet 22A have the salt shaker phase plugs, which did you say that you liked better? I will pull mine out of storage soon to see for myself. I really appreciate the info thanks.

Best regards Moray James.

I guess sometimes they actually change things for the better. BTW, if you ever get the urge to put 22XT+ diaphragms on your square magnets, they'll work, but you have to cut away the plastic a bit to fit around the bolts.

Kloss	I have a 40in TV and a 55in TV both used in fully horn loaded systems. Since dispersion is controlled the surface of the TV has little to no effect on sound quality. And TV is needed to use internet for hi res music movies games etc.

You live an hour north of me. I live in Howland Township, north of Y-Town and east of Warren. I am incredibly curious about low powered amps and high efficiency speakers. Up until just recently I have been using my Plinius SS amp, etc and then I picked up a Pass F5 clone on an impulse buy. I run it with a tube preamp and a pair of Nola Boxers. It soounds great at only 25 w per side. The boxers are great sounding standmounts and not bad for sensitivity at 90db 1/1. They do play rather efficiently due to the flat response along the frequency range. Now I am looking into HE speakers and thinking about picking up a SET amp to try.

I may want to take you up on that offer since I have never really heard any low powered amps and high efficiency speakers. Reading about them just isn't gonna cut it.

Does 95dBSPL/m count as Hi-Eff?

These are DIY Synergy horns (inspired by Danley), three-way drivers within a single point-source horn. Woofers fire through horn, but are also ported.

Thanks Bill: those are really great and interest me to no end. Is there any discussion about slot loading of the cabinets? I cannot find much info on slot reflex loading except that I understand it to have a wider band of action than a typical symmetrical reflex loading. Are a pair of 24 -28 inch wide synergy horns in the works anywhere? or even the equivalent of the SH50 (size wise)? I have a pair of McKinney Unity Horns and am wondering if some small long throw woofer could be added? I will have to follow the lead of someone else on this as I have enough problems with a calculator much less playing with HR. Thanks for any leads. Best regards Moray James.

Hi, Moray James,

Sorry, I don't have a source about slot porting. I just used the shelf port because it helps stiffen the front panel. i used WinISD's calculations for the dimensions, but those tuned the box about 20% too high so I had to narrow the port to adjust. I don't know what caused the error, maybe the compression in front of the woofers? Anyway, it was easy to fix.

The horn is 24" wide as it is, and controls horizontal pattern at 90° to about 450 Hz. The woofers and ported box work down to about 40 Hz, though the horn doesn't load below 450 of course (the geometry does still beave as a point source to low frequencies, though). I crossover to separate subs at 60Hz, though, which extends lf better and allows for better placement of subs for bass.

The build thread gives all that is really needed to build my version if you have a table saw, even crossover schematic, though the thread needs some organizing to make it easier to follow. This fall I'll be making another set of the horns and plan to take step by step photos to make it clearer. I like the smaller sealed-type cabinets like Tony Seaford made for his versions, will probably try those too.

The only options for these at present are doing diy like this, or getting real Danleys (such as SH95, which are expensive though not really much compared to what people pay for TAD, big JBL, old WE, or high end audio plain old cone and dome speakers). I'd like to do kits but haven't been able to get permission from Danley Sound Labs; Tom (tomservo, here at AA) did give me the ok to post the build details on mine though. It's definitely worth the effort, they're the most realistic and musical speaks I've ever heard.

Good luck, Bill
