Hi Everyone.

I am a newby to the site, and the world of horn speakers. I would like to build a 2way system. Bass cabinet, horn on top. I have quite a small dedicated listen room 13ftx13ft. So would like to keep the footprint as neat as possible.

I am a fine furniture maker so building the cabinets should not be a problem.

I like the idea of a small multicell horn on the top of the bass cabinet.

Can anyone help with drawings (plans) for a suitable system that will work in my space?

THANKS.

I'm trying to think of a small multicell. Did you have one in mind?

Hi David.
I really am a newby to horn speakers.

I guess because of the size of my listening room. I will need to use a 10 or 12 inch bass driver.

So the multicell horn will need to match up.

I am a cabinet maker first. Audio nut 2nd. I really need a design to work from

I would be grateful for any help, advice, and suggestions. with drawings and driver selections.


Thanks again.

Steve.

The JBL L200T3 might be a good project for you. If you use the search function in these forums you will come up with a number of threads to read.

Thanks David.

I noticed on an old thread. You had some nos 811 horns for sale.

Have these all gone?

Did you build a system using them?

Thanks Steve.

Hi Steve,
Welcome to the forum.

Your request is a little bit tricky. The words small and horn, especially multicellular horn, don't normally go together. Horns project a big soundstage and need a big bottom end to keep them in balance.
There a lot of ideas that can find by found here by searching and digging around, not a lot of complete plans though. Some of the fun is building something that works for your particular circumstances and the drivers you are able to acquire.

Here are a couple links to horns you may want to consider.

A smith horn:

or a turned horn:

Do a search too for LE14H-3, which is a great driver for a relatively small 2-way. Also the LE120H could work.
I like the 708G 8” woofer too. A small 2-way with a 2407H on a turned waveguide above a 708G would be a fun project.

Hi John.
Thank you for your responce and for the great advice given.I must complement you on your fantastic systems. and your obvious woodworking skills. I particularly like your smith horn system.
Could you tell me a bit more about the bass cabinet design?
I have a pair of JBL 123A Woofers available. Would they work with the smith horn?
Is the 2435 HPL driver a newer design or vintage?
Do you know the present cost and were they are available?
As I mentioned in my opening to the thread I really am a novice to horn speaker systems. But as a cabinet maker and music lover. Building the horns and bass cabinets really appeals to me.
One last question. Do you know were I can find a drawing for the smith horn?
I thank you again John. For your welcome, and much appreciated advice.
Steve.

I'll have to send you searching for some of this info. There are a few posts on Smith Horn plans here. Use search and try "2397" "2397 lip profile" "1200hz smith horn"
2397 is a smith horn optimized for the 2 in drivers like 2440, 2441 and others.

Here is the original thread for the boxes in the picture:

Check out this thread on another beautiful 2 way system.
http://audioheritage.org/vbulletin/showthread.php?t=19399&highlight=santa

I also did a little searching on 123a and it looks like these work best in a fairly large box. Otherwise I don't know how well these would work for what your considering.

Another path you can look down is "4425" and "DIY 4425". The 4425 is a fairly small horn 2-way with a 12in woofer. Reading up on this can't hurt, even if you wanted to substite your own horn.

The 2435 is one of JBL's newer drivers. They are built mostly for the Pro Market. Here is a link to the JBL Pro transducer list:

They are pricey, but show up on ebay from time to time for a lot less if you want to go that route.

Hi John.

Thanks again for all the links.And answering all my questions There are certainly a lot of very talented people on this forum. (I'm hooked).

I think I'm going to go down the smith horn route. So I will need to locate some drivers. As you mentioned. I think the LE14H-3 would be a good choice for the woofer. It would allow me to keep the cabinet footprint smaller.
Could you recommend any other drivers for the horn? I think the 2435 maybe a little to expensive for a first attempt.
I did a quick search for LE14H-3 but could not find any for sale. Do you know were I might find them?

I thank you again.

Steve.

Here is another thread that gives a couple sources for LE14H-3s.

http://www.audioheritage.org/vbulletin/showthread.php?t=19580

Smith horns are a fun project. If you decide on the full size 2397, then I would recommend finding a pair of 2440s or 2441s. You can try the auction sites, or put out the word that you need some.
Otherwise for the smaller horns, you may have to see what you can find there are a lot of options. I've played around with 2420, 2470 and 2425 and a few others. They all sound good, but a little different.

Thanks John.

I think I have a plan in place now. I will report back as I move along.
As a woodworker the smith horn project really appeals to me. Although I am not to tech savy regarding cross-over networks. I will work my way through it. (I'm hooked

Thanks Steve.

Hi.

Thanks for the link.

I guess the M15 is a commercial design.I bet it sounds as good as it looks.

Thanks for the responce.

I like the look of the M12. I hope to be building something along These lines shortly Using the smith Horn. The M12 has a very neat footprint.
