I am beginning to earn money from a new stream of income. I am a musician and I am committing the ultimate sin. I'm starting to DJ! There I said it.
I do have a bit of twist compared to your average dj. I will be spinning real vinyl and I will be using mono records. I did a "pilot" gig at a senior center in front of about 50 people. I set up my DIY Rek-O-Kut table, Scott 299d into my makeshift mono speaker. I stacked my guitar speaker cab on the bottom (2 JBL 123). On top two Steven true sonics FR80's and a cheep tweeter.
The old folks and employees love the "show". I spun an hours worth of 50's big band, swing tunes and hits of the day.
My week spot in my chain is my speaker. I want the highest fidelity I can get but I also want A visually interesting speaker to draw attention to my set up and show. I have thought about the Vott with a horn on top and some others. The other aspect is I must be able to move it on my own and fit through a club door on a dolly.
Please let me know what you think!
I will send a free copy of my latest CD to person who's suggestion I use.
Thanks,
Damon

Kidding!
Geez, does anyone have a sense of humor around here? :)
But, to answer your question, ANY hi-fi speaker can be used for mono apps. If it's hi-fi in stereo, it's hi-fi in mono.
This will irritate some folks, but the Altec A7 isn't hi-fi. It's easily loud because it's efficient, and it'll totally fill a 40x80x10 room with ease with a fairly small amp, and some senior folks might remember seeing them "back in the day", but it ain't hi-fi unless you're using 1960s equipment standards.
I don't know anything about the A5. Never heard one, never saw one.
:)

There was a great deal of HIFI in the '50s. HiFi preceded stereo by at a decade at least, being an step up from Victrolas and Westinghouse radios.

"but it ain't hi-fi unless you're using 1960s equipment standards."
I think mono play back must have period correct equipment in order to capture what the musicians, engineers, producers... where hearing. I have only been spinning mono for about a month and I have been blown away by the dynamics. Even on my "pieced" together system. I think the best period correct "Hi-Fi" speaker would be an Altec 604. I will go with a 604 for my home play back but for DJ-ing even though not as accurate an A7 or A5 may be the way to go.
Here's a picture of a normal LaScala (original version) with the K402 on top. The K402 is literally larger in height/width than the speaker itself!!
In the pictured unit, the mid/high horns are totally being bypassed in lieu of the larger horn on top. He's simply keeping them stock.
All you really NEED is the bass bin. You could even have those built (and have handles added to the sides!)
This is also a JubeScala using the much smaller K510 horn. ON axis, it sounds great but does lose some control when going off axis.
It's the little horn that could!
You can see with some woodwork, the K510 would fit nicely inside the top of the LaScala.
Again, he's keeping things stock for possible resale, otherwise, just bypassing the internal mid/high horns and going 2-way
Thanks for the info on the K510 horn. I thought they may be out of my price range. They look so cool! I love your out door theater idea. Must be a lot of fun!
I think the best bang for the buck and "wow" visual factor is for me to try and score a beat up single A5 or A7. Fix it up.
Is there a horn that disperses better for smaller rooms that I should look for?
Is the A7 a lot heavier than the A5?
Should I look for certain models or years?
Both systems have the same bottom cabinet, either 825 or 828 depending on the year. Older cabinets could be lighter because they used 5/8" ply for many years. Any of the cabinets benefit from extensive additional internal bracing.
The A5 uses a large format compression driver whish is a bit bigger nad heavier than the 1" drivers used in the A7 and A7-500 systems.
Also an A5 will typically have a multicell horn which is bigger and heavier than the 511 sectoral horn of an A7.
My A5s have tar-filled horns which are really heavy. I've also sand-filled the horn flares of the lower cabinets which added about 150 lbs to each cabinet. They don't get moved much.

Thank you eso. The info is very helpful. I cant be to picky at the moment. A5 or A7, klipsch, the big JBL horn, mantaray horn with bass bin. I'm in CT about hour out side NYC. Been searching Craigs list and e-bay. Nothing close enough yet.
I would love to hear one of these speakers before buying for the "looks" and hoping they meet my expectations.
Seeing if I can upload a pic. As mentioned above, that is the huge K402 on top.
These show up all the time on ebay and CL.
Those are 2 x 15 cabinets on the bottom for an idea of the scale.

And they are priced right.
"Seeing if I can upload a pic. As mentioned above, that is the huge K402 on top".
I like the looks of this! Is it a two way with a simple cross over?
Where can I find a K402 and how much do they run second hand??
Hear is a pick of my table I just finished.

Well...it's not THAT easy.
The bass bin is the lower portion of a LaScala II. You can ALSO find a older LaScala and use it (with it's other 2 horns) or, you can bypass the top two horns and use the huge K402.
The K402 is only in about 25 or so homes nation (actually world) wide. They do not come up for sale as a general rule. You can however, buy them direct. There is a specific way to do it so if you decide to pursue that course, let me know and I'll get you on the right trail so it doesn't get screwed up.
The K402 is "about" $1,000 (maybe 1,200?) EACH. This includes the horn lens, driver (K69 tweeter driver) and mounting tray. It is literally, pull out of box, plug in and play.
It is being used by most in an active crossover setup (I have those paramaters) however, there is evidently a passive that has now been designed for it from what I understand. I do not have a diagram of the passive. The active/passive items are not included with the purchase.
Honestly, what I'm doing is trying to find beater LaScala cabinets that I can get for a song. Maybe resell drivers/horns since all I really want is the bass bin.
I'm looking to collect them, slap a K402 across the front three and maybe add two more for rears with the K510 mounted inside them. And use them at my house in TN for outdoor movies!!!
I have already done it with their big BIG brother. It was a blast. I had the mono-stack big brother (picture attached) reading peaks of 114 db's while playing outside 52' away (measured)
CLEAN dynamics but the MWM is not something easily carried by one person. A mono JubeScala COULD be managed by one person if you maybe had a dolly and/or chopped the top off to make it like the one pictured.
This is the smaller K510 on top of a different bottom. Easier to carry, sounds just about as good when on axis, loses some control as you move off axis.
You can see by the size that it could easily be incorporated into a tophat.
By the way, it uses a 2" driver
How about a Little Horn?
Klipsch LaScala bass bin, mated with a Klipsch K402 (or if you want to build it inside the speaker itself, the much smaller K510 HF horn)
Called a JubeScala. Perhaps mate it with a sub and be amazed at the quality, impact and clarity of sound.
Though it will fit through doors, I won't say that it won't be a pain in the hiney to do so!! (I'm speaking from experience, especially when used with the HUGE K402 horn)
You can biamp the speaker. I presume you already have XLR stuff in your equipment so you might already have enough stuff to biamp it.
A Karlson K15 topped with "The Tube" could do a great job of making mono sound big. Buying a single GPA 416-8C could be very good along with a decent compression driver. "The Tube" can be DIY'ed easy. Some of these folks might even recognize this 50ies design!
Smith horns do mono well too IMO.

A Vott might be a good choice you may need a bit more power than the Scott for most any loudspeaker you choose.
I really like the way the Altec A5X looks with that horn on top. I think it would fascinate people who have never seen one. I would like to make or find a SE 2A3 mono amp to drive this system.
I forgot to add one parameter of my request.One of my goals is to find a speaker that will "fill" a room with music and sound good from any seating point. I know I'm asking a lot but I'm sure some speakers are better than others.
Your going to need more than a 2a3 to entertain 50 people even with a horn. The Altecs are designed for even coverage a A5 with enough power is good for a 700 seat cinema.
"Your going to need more than a 2a3 to entertain 50 people even with a horn. The Altecs are designed for even coverage a A5 with enough power is good for a 700 seat cinema."
How well will an Altec A5 do in a small room of 10 people? How many watts do you need to drive an A5 or A7?
In the upper right in this picture you can see one of my hanging A5s. I use these for music in my shop. They are biamped with marginal EV electronic crossovers and Sonic Impact Super-T amps with about 10W/channel. Using my computer's iTunes or my phone as a front end the pair will easily play clearly over any machine in the shop.
These are very old A5s, with 515b on the bottom and 288b on top with tar-filled 1005 horns.
While I'll agree that a 2A3 is not enough power, you might be ably to get away with a 300B in a small room. You will likely have points with significant compression due to the amp running out of gas though. To really keep them open and alive a good amount of headroom is always a good thing.

Seeing these horn and realizing that I will never be able to build a pair myself is painful...
Cool looking horns! I am jealous of your workshop.
I will be using a world class DH SET 2a3 amp. I'm not worried about having enough power. As of now my 2a3 amp is not done yet so I'm using a Scott 299 d .
Thanks for the info eso.
Expect significant compression of transients and loss of dynamics in fff passages because the amp will be constantly running out of gas.

I would suggest between 8-75 watts. A7-A5 would work just fine for small groups I use a Altec A5 and a A4 for computer speakers...Run them on 30 watt class A SS.

WOW!!! How big is your computer! :)
I collect loudspeakers.
