I consulted with Def Tech on whether to box them in the ceiling or not when I installed them, and if not, what should I put over them. They said don't box them, with the same description GE gave to you. So I asked them if laying Roxul SafeNSound over them would work. They said that would be fine. So I have them installed and while they sound way better than in the open, they do not sound as good as the PM1000s which are the same drivers. Overall I am happy with the sound though and Atmos is great even in the Dolby Surround mode. It's much more enveloping and you feel like you are in the movie.
We are very thrilled at Mark's review of this system and we are looking forward to setting it up at CEDIA. This system was not necessarily conceived of to replace a more elaborate Atmos System with large floor standing speakers, such as we demo'ed last year at CEDIA, but rather to show a very high-performance, nearly invisible, alternative that may appeal to many listeners. Reading this posting, I thought that perhaps there was not a complete understanding of what is going on, so I thought I would chime in.
Regarding listening to in-wall speakers open mounted, obviously this does not work. All of these are designed to go in-wall or in-ceiling, which provides an infinite baffle, which prevents cancellation of the front and rear backwave coming off the woofers. When open mounted, you would get a complete cancellation of all low frequencies below several hundred cycles. The infinite baffle that the wall provides is similar to what happens when the speaker is put into a cabinet, although the wall mounting, in effect, acts as a larger cabinet, which extends the bass response. In terms of comparing your Definitive in-walls with your ProMonitor 1000s, although the drivers may seem similar (I can't comment specifically on the bass/midrange driver) but the tweeter, although both 1", are certainly not the same (the one in the in-wall uses a different magnet structure and I would imagine there are other differences). Also, I believe the crossover is different. Additionally the ProMonitor has a passive radiator, and the topology of the tweeter mounting (coaxially in the center of the driver) is different. In the 7000s, there is a very specific performance reason why the 7000s have the tweeter mounted as it does, rather than coaxially, as this works better. And the coaxial mounting of the tweeter in the Definitive in-wall (which is typical, our 525s and 650s are also)) is certainly not the same as the baffle mounting in the ProMonitor, both in terms of the topology around it, as well as its effect on the driver behind it. I hope that this clarifies some of this. All the Best, Sandy
