I asked him about the FR for in home

use, he said;

"The response shown is for a single 12Pi horn used outdoors. If used indoors or in groups, the response is made more flat. That's just the nature of basshorns.

 

See http://www.AudioRoundTable.com/ProSpeakers/messages/260.html

 

The response curve at the bottom of the page is what you would expect to see if used indoors or in a group.

...

"But it's a very large horn, so I don't think it is suitable for use in a home. I wouldn't want that thing in my house. It's for large concerts and stuff like that. "

I'd use it in home //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The 12pi basshorn subwoofer is 45" x 45" x 28", which fits nicely in semi trucks. Trucks are 90" wide, so truck packs are usually 45x45x22.5 or 45x45x30. The 12pi basshorn uses a pair of LAB12's in push-pull which reduces harmonic distortion. It also has a heat exchanger which increases power handling over 225%.

Dual 12" Eminence LAB12 woofers with heatsink. //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

I thought they were building a customer woofer for this project? Need to

check that.

That is a big box actually //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

You can stack 3 laying flat to make occupying 45" wide x 7 foot tall, then do

two columns to make it 90" x 7 foot tall. Six 12pi basshorns in the room against

the wall. 12 12" woofers, $145 each, $1740 for woofers.

[or stack 8 and cover the whole wall -- hehehe)

.. but if you were going to do this, you might as well make the whole room

a custom made bass horn that is part of room structure //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

He's going to sent me the plans. You can ask him too, his forum here;

http://audioroundtable.com/PiSpeakers/

Says, he's using the Eminence Lab12 woofer, two 12" per box.

But, I thought he was having a custom woofer made for this project,

a modded Lab12 with magnum features. I'm too lazy to find out..
