Have client that just won't go for the big black box. Nowhere to hide it so my first instinct is to go up.
Problem is the ceiling is 20' high and I've never used an inwall or inceiling sub. I know it would have to be powered and in the ceiling would have to bring on a whole slew of potential rattles etc.
Curious what others have done.
Thanks,
CMack

Have used both and prefer to use in wall. The amp for the sub can be placed with the rest of the equipment. We've used the Niles PSW-8 with either a rotel or adcom running it...

Have you considered under floor?

Larry,
I'm pretty creative but the flooring is concrete so that's out. At least the cost of the retro would be huge in comparison. I don't think he wants a sub that bad. But I'll keep it in mind for the 2nd floor and up.
Even then wouldn't there be a problem with cracking sheetrock over a period of time? Or even just the bass bleeding below. What experiences have you had?
Jose,
I'll take a look at the niles.
How do you wire that? LFE out of the receiver into an input with a y adapter into L/R inputs on the 2 channel amp?
Thanks,
CMack

If you use an in-wall/celing, use the back box that was designed for it. it.[Link: sonance.com]

RBH (WS-100 or FS-12) and Snell (AMC SUB 12) are good too. These each need their own amp as well...

We've used a Jamo (cant think of model number off hand) in-wall sub. It's wired off 4-conductor from your amp and comes with a crossover that goes in the wall below your sub(just on the bottom plate). It produces decent bass, but not like a stand alone sub does.

I setup my Dad's home theater and we used all Inwall stuff from NHT, superone's in wall and round CS6.1 for surrounds, and in other rooms for ambient speakers. The in wall sub I was a little worried about because it is only and 8" woofer and it is a very large room with 10ft ceilings. But after installing everything the system sounds great, the sub has plenty of low end for movies and music. The amp is with the gear and can actually drive another 8" woofer if desired. They are under the architectural series on the NHT website.

We install more in ceiling subs than anything else. In high end custom homes without a cabinet to hide a powered sub (which is really the best) we often use the Speakercraft in-ceiling sub. The thing I wanted to add to this thread is that getting the ceiling sub in the corner of the room produces a much more dramatic bass response other that putting it more central to the room or between the rears (especially if the sub is just going to be wired passively).

We do a lot of in-floor subs and prefer that method to any other out there. The in-floor approach gives us the ability to scope a room and build the enclosure to work with the room acoustics and avoid the "generic black box". Under the floor allows for the most flexibility in design and tuning. A good bandpass enclosure can have a volume of over 6 cubic feet when tuned to a large room and a vent that is over 30" long. We have also found that the mounting of the subwoofer enclosure to the subflooring from underneath gives the highest level of low frequency transfer. the cosmetics of a matching floor register also means the sub is all but invisible unless you know it's there. The only drawbacks to this apporoach that we have found are the level of technical skill required to properly design and tune an enclosure (there is good software out there, but it still requires a higher than average understanding of room acoustics and some wookworking skill) and making sure that you can physically get a 14" x 14" x 42" box under the house and to the location specced during pre-wire. As for amplification, the amplifier is matched to the driver and the power requirements of the subwoofer, and the wired speaker level. This also helps to avoid noise that can be induced over in wall runs of low level signal(just because you avoided the electricians' wire, doesn't mean they stayed away from your signal wire after you left). We custom build roughly 75 percent of the subs that we install, even the ported, or sealed ones in cabinets. I understand you have a concrete floor issue so this approach is probably out of the question, but may be some food for thought for the next install.

CMACK - Have you considered the ramifications of a ceiling mounted subwoofer 20' up? We had an unpleasant situation where we had to rent scaffolding to service the subwoofer (and the client had to hire movers to clear quite a bit of furniture. Good luck!

Approach with caution and do your site homework carefully.
