Is this in-wall speaker Ultra Certified as an LCR or only as a Surround speaker? Thank you.
A shopper
on Jan 7, 2022
BEST ANSWER: The speaker is Ultra Certified regardless it's used. However, the speaker wasn't designed for use as a surround speaker. The reason is it includes substantial bass capability and abillity to project bass at reference sound levels whereas surround sound speakers typically do not require this capabilitiy. Additionally, this speaker is large in size which most users would consider undesirable in a speaker used to project only surround sound. Nonetheless, this speaker would perform well as a surround speaker although the majority of listeners would consider use for this purpose as superflous.

I have to “stud out” a horizontal opening with 2x4’s. What would be the ideal size for this speaker?
STEPHEN L
on Aug 7, 2022
BEST ANSWER: This speaker is designed for an infinite baffle wall. If you turn it horizontal and create a space for it Your open space will be Y axis vertical along the long side of the horizontal speaker. You can make this a comfortable size, I suggest about 8“ above and below to a supporting cross brace to give the drywall support near the speaker.

See Background below for some context.
Questions: Q1 - Is it ok to have THX-465IW speaker 1" above a horizontal stud and 1" below horizontal studs and almost flush with L/R framing studs (a) for the installation tabs and (b) for sound? Q2 - is there a need to have anything behind the speaker or is it OK for it to empty out onto the fireplace cavit (see below). Q3 - what are the recommended Front LR, and Rear LR and surround and atmos speakers to complement this center channel?
Background: I am in the middle of a family / dining room remodel. Room is 28x16 with the center channel location approx 12' from the RHS of the long wall. Besides the kitchen, this is the only shared space in our house so this is where we are putting the "home theater". WAF is paramount and important for me too, so we're gong mostly in-walls with a couple of Heresy 1's on the floor for retro vibe, vinyl playing, and potentially as Front Wide LR (TBD). There is fireplace installed with cool vent (FirePlaceX CoolSmart) heat displacement system to push the heat in a vent up and round the back of the TV in the wall space. This leaves limited space for a center channel speaker but it is doable. We will put a smallish (43") Art TV for casual viewing / ART display and I will make an acoustically transparent screen for movie night, sports games and such, size TBD but likely 80-100" wide for a short throw projector and a seating positions 4' to 10' back from the screen. Fireplace cavity is 5' wide by 8' high by 18" deep cavity. which includes the fireplace, with cut steel plate, and both flex and sheet steel vents.

Yes, this is ok.
Q2 - is there a need to have anything behind the speaker or is it OK for it to empty out onto the fireplace cavit (see below).
Is there a radiated heat issue in there? What about the fireplace heat recovery unit itself is it steel that can vibrate under high level listening like a movie with explosions etc? You can fire into an infinite baffle as it is designed for such but be careful what is nearby.
Q3 - what are the recommended Front LR, and Rear LR and surround and atmos speakers to complement this center channel?
Rear 34368
Center – 34366, 34367, 42830
LR – 34366, 34367, 42830
Yes, this is ok.

is there a mounting kit for any of the Monolith In-wall speakers? I'm having sheetrock installed, and would rather have the sheetrock guys make the cuts than do that after the fact.

I'm trying to plan a HT system. I'm thinking I'll use 3 THX-465IWs (LCR channel), 2 M12-VT (subs), 2 THX-275IWs (in-wall surrounds), and 2 or 4 in-ceiling atmos speakers. Does this setup make sense? And what atmos speakers should use?

Happy
Happy so far! I went with 3x 465 for the LCR, 4x 365 for side and rear surrounds and 4 of the monoprice calibers for height, and 2x 10? subs of a different mfg. Monolith 7x powering the main speakers and Anthem MRX740 8k powering the heights. Very clear. I used 5/8? SoundBreak XP drywall and Rockwool safe n? sound in wall insulation. Very happy with end product.
