DIY multicell horn

[thevott]

Thanks Mirrophonic,
I have made drawings similar to that. That is, incorperation the horn into the stage cavity. It makes perfect sense.

My wife can read me like a book, I'd never get away with it!

I think I'll just have to build my dream venue and call it a business

Lots of municipal parks have summer concert series. Can you imagine the draw you would get with an in ground, poured concrete, LF horn system! Maybe even combined with a water feature that distributed a fine mist to cool the audience when the music starts smokin'. Well, maybe I'm getting a little off topic.

"That is, incorporation of the horn into the stage cavity"

...OR in a split-level sunken living room....

It seems a lot people like LF horn in here but i noticed that LF horn is used less and less.(I mean the modern speaker) Why???

[thevott]

Larry,
It has everything to do with size. It is easier to transport smaller direct radiating LF enclosures in tour-sound applications. There are some sacrifices though---and directivity is the main one (IMHO). I must say, however, there seems to be a number of folded sub-bass horn systems in current use which definitely speaks for itself.

Long live horn systems!!!

Larry,
I'm sorry, you probably meant home systems not tour-sound. I'm still thinking 'venue', which might as well have a permanent house horn system anyway!
Nevertheless, again size seems to be the issue along with big amplifiers (which can drive little inefficient speakers) and strong glue (so the speakers components don't fall apart). The public has been so passified over the last half century or so on direct radiating systems that most people have no idea how much better horn systems can sound (again in my humble opinion).
Even my hodge-podge 815/511B horn system (which only horn loads to abit below 100Hz) is jaw dropping to most people,...and with guitar speakers no less!! Ah!!! There's gotta be somethin' to this horn thing!

VOTT,
When you say that you "opened up" the 815's for improved
sound, I have an alternate idea: You could close this
front port and open the rear speaker access (if they
have a rear panel like the 210's) creating a "Shearer/Mirrophonic" effect.

To eliminate/attenuate the rear waves, add wings - or
a wing if corner mounted - or cut a hole in the wall to
make adjacent room/garage the 'infinite rear chamber' (do it while your wife is out shopping )

I like your infinite baffle idea. My garage/workshop/doghouse/home-away-from-home/"my space" is located adjacent to my basement den where all the audio is. If I turn the common wall into an infinite baffle mounting for the LF, I could mount the 1005's to supply the den and mount the 511-90's in the opposite direction to supply the the garage. I like that idea.

Charles:
Yes, with the right drivers and a little EQ, you can have
superior bass - in two rooms !
