Might as well be a company that provides great support. They have free documentation available (SIM guides) that are more detailed and better illustrated than some plans you pay for.
The one thing I would caution is your budget. If it's tight, let them know. Diminishing returns apply. If you go in wanting the best, they're going to give you the best. If you're on a budget, there are a lot of things they can do to drop the price without loosing much performance.
One other thing to keep in mind is that a number of their solutions are work arounds for less than ideal decisions made while building the room. You can save yourself the expense of having to use many of their solutions by avoiding the problem in the first place.
For example, if your room is big enough, you can put 99% of everything you need inside of the shell. Lights can go in a soffit inside the room, on columns built within the room, or into the "beam" sections of a coffered ceiling. That avoids having to use backer boxes for lights. Similarly speakers can go on the walls covered by fabric or in columns. That avoids backer boxes for speakers. Wiring can terminate into surface mounted receptacles to avoid having to wrap conventional outlets with putty pads. In general, minimize the number and size of the penetrations into the room, so you don't have to buy putty pads & backer boxes. Similar for air circulation... plan on having forced air HVAC drops & a return in the theater so you don't have to build a dead vent. Treat footfall noise on the source side, so you don't have to resort to laborious methods to fix after the fact.
Thanks for the info! My budget is tight, so I'll make sure to let them know.
1) "or into the "beam" sections of a coffered ceiling"
How much height does recessed lighting need? I am working with 8' ceiling, (minus clips/channel, DD, a riser) so headroom is at a premium.
2) "Wiring can terminate into surface mounted receptacles to avoid having to wrap conventional outlets with putty pads"
So this would be running the electrical wires through the soundproof shell and then mounting an outlet on top of the drywall so to speak? Or another option would be use conventional outlets, but mount them inside columns?
3) "forced air HVAC drops & a return in the theater so you don't have to build a dead vent"
Not sure what you mean by this? Isnt the dead vent to isolate the noise from the forced air drops/return?
