If you need to put it in another enclosure then I'd try and make that sucker fairly dense to keep resonances to a minimum. Won't be optimal, but better than no sub at all.




Here here... Surely we all want the best sounding HT we can build/buy. For some of us there are zero restrictions holding us back, others have certain trade-offs to contend with. If it were true that it wouldn't be worth putting together a HT if you couldn't do it optimally then I wouldn't have a HT right now because our HT doubles as our sales/presentation room, and therefore has many compromises built into it.

But it's still amazing to watch movies, listen to music on! It could be better, but I'm not complaining.

Ok heres what I am coming up with. The sub will be on the floor recessed into an in wall column with the front of the sub either flush with an opening in the column or even sticking out a few inches. I can play with that to see if it does help the sound. I figure i will use chipboard above and begind the the sub, green glue, drywall for finishing. I will insulate the entire inside of the column. Do you think I should use any sort of acoustical panel inside of the cabinet over the drywall?

I don't think any of that will matter so long as you hook it all up with Monster cables!

Hey check this out. Axiom displays pictures of the W22's in use in several HT's. In one of the pictures a theater has what looks like 2 EP350's recessed into the walls. This is pretty much what I am looking to do. I would love to know who's room that is to get their thoughts on enclosing the subs.....

That was a room mock up they did for a home show a few years back. The people they were doing it with made them do that. I don't remember if Amie said the sound was affected or not, but the implication was that Axiom would rather that they hadn't had to do that.

That said, I think it's a pretty cool look, myself.

This is known as constrained layer damping and is extremely effective in reducing panel resonance. I would also suggest putting horizontal dividers inside the column to break the large panels into a series of smaller panels with a higher resonant frequency: pushing the resonant frequency above the range of the sub. MDF or ply will do just fine. Anything you can screw and glue to the chipboard.

Thanks Fred, This gives me some confidence that although not optimal I should get decent enough sound from it if i build it right. Hey if it doesnt work the worst that could happen is I slide the sub out, close the hole and let it run free!

The other option you have is to use the cave as the sub's hibernating spot if you don't like the way it sounds in there. What I mean is that maybe to keep the wife happy or whatever it stays in the cave most of the day. Then when it's movie time you can slide the sub out and place it where ever it sounds best & enjoy the show. Show's over and sub goes back to sleep in its cave.

I'm not sure if I heard correctly but this is for an EP350 right? And someone else pointed out that the 500 is the same size, is that right? If so this is a good thing because if you're building a spot for it I'd hate to see you outgrow the 350 within a year or so & want a bigger sub but be stuck with the 350 because nothing else would fit into it's spot.

But if you can safely upgrade to an EP500 and still fit it in the same hole, then that's a plus.
