[Nearly Full-Range Multiple Entry Horns (MEHs)]

Has anyone completed a slightly smaller MEH using 8” or 10” woofers?  
it would be great to get down to 80-100 hz with a horn about 20” wide still keeping a roughly 90 x 60 pattern. 
 

Is this possible?

Yes, I'm aware of the limitations of some listening room sizes to handle them.  "Cheap" is another issue, not related to acoustic performance.  That's a barrier to entry for some DIYers that are severely budget constrained.  But when you look at the cost of a new pair of Cornwall IVs, I think the cost of the K-402s isn't quite so bad.

 

If that's all you can handle, then that's it.  The listening room itself is the limitation.  However, I would also point out that I've seen many people state that they can't handle the width when what they are really saying is that they don't like the visual width in their room.   I try to go with the acoustic performance first.

 

This actually works quite well (I use AMT-1s on top of Belle bass bins currently as my surrounds in my 5.2 array, and they are outstanding).  Using K-402-MEHs and/or Jubilees, doesn't really constrain where the listener is located, however--anywhere from sidewall-to-sidewall in multichannel music mode (LCR).

Chris,

Sorry for the delay. Thanks so much for your comments and encouragement. 
 

In reviewing other posts, I see that K402’s are “only” 39-40” wide. For some reason, I was thinking they are 46” or more. That error in thinking adds up for an LCR set. (Well at least 18” or so less than I thought). 
 

I will keep reading all the various threads. A wood K402 set would be very interesting. My AE 15” subwoofer would only need to cover the very lowest organ pedal tones and concert bass drum notes.

Chris,

I agree that an MEH with a low end cut off only extending to 300 or 400hz makes little sense.

Your K402 based MEH look to be astounding, but the 402 is really wide for a lot of rooms, especially if used LCR.  And,  it exactly cheap either.😊

 

The sweet spot for me would be an MEH using a 2” driver crossed around 400 to dual 12” (or 8”?) woofers mounted on the sides firing through the horn.  Low end cut off of around 80-100hz.  Preferably 24-30” wide.  
 

 Perhaps this is pie in the sky. 
 

Maybe the better solution is the Peavey FH-1 + 2 Large Heils from your other thread.
