New HT build v4.0
This will be my 4th home theater I've built in as many homes. This will be my first starting from an unfinished basement space and with a more advanced knowledge of what I want to do. Previous builds I either had a finished basement to work with already or started unfinished, but didn't know how to build the space best. All my last gear, which I loved and thought would be the last I'd buy, got sold with my last house to close the deal.
This time the unfinished space is the biggest yet, 34 ft long 14 ft wide and 9ft high. It is a fantastic spot in my basement, where I don't have to walk through the room to get to another room and as big as it is, is still less than half the square footage of the whole basement we are finishing. Construction will be done by a local contraction who specializes in basements.
My question is: am I doing this the best way?
I have a solid idea of what I want to do, but would love to hear from the accomplished and armchair home theater design buffs here.
Bonus points if your are familiar with DIYSG speakers.
I already have a 150" acoustically transparent screen and I plan now to have that on a false wall set 2 1/2 feet off the room wall. The false wall will be cover in the screen and acoustical transparent black fabric.
For speakers I have settled on DIYSG Aggressive 1299, ported, for the LCR and Volt 10's for surrounds. I would like 2 of some Ultimax 18-22 based subwoofer design, possibly sealed. Atmos speakers, 4 of them, will be wired in the ceiling and installed down the line.
I'd like to find a cheaper option in terms of speakers, but I like boom and this is a big space.
Projector and receiver/amps will be purchased after the room is built in late February/early March.
Just to the right of the screen is a small alcove where the rack will be to hold all AV and the home's IT set up. I plan on running 3-4 20 amp dedicated circuits to the rack. I will get some Crown or Behringer amp to supply at least 1000w+ to each sub, and am looking for a good amp set up for the LCR's too. I'll have 3 20amp dedicated circuits run to the rack.
The ceiling will be double drywalled and insulated with Safe and Sound insulation as my master bedroom is just above.
The questions I have: are 1299's the best as they are the most per speaker I'd like to spend, what Ulitmax based sub enclosure would be best (I'd like to stay smaller, mini marty, VBSS, Devastator and more simple sealed box), and any other idea for ceiling sound transmission dampening (other than a room in a room or resilient channels) and if I have enough power to the rack?
This won't be as dedicated a space either, it will also server as my home video studio where I will record clients. All acoustic wall treatments I'lll have on the walls for listening to sound are perfect for recording sound too and make the space a tax right off.
