Basement home theater acoustic treatment advice

[rolltide]

Hello friends - I’d like to buy some acoustic panels for my basement home theatre and need some advice. I attached a floor plan and photos. Here are those and a video walkthrough:

My home theatre is 16x11.75 feet with eight foot ceilings, roughly in the left side of my basement next to stairs leading to the main floor. Behind my recliners is my standing desk and office. The ceiling has an HVAC soffit/tunnel running across the room. Here’s my setup:

7.1.4 system

• KEF R6 Meta (Center)
• KEF R3 Meta pair (Front left and right)
• Two KEF Q3 Meta pairs (Surround left and right and rear left and right)
• Two Kicker KB6 pairs (on-ceiling Atmos front left and right and rear left and right)
• Power Sound Audio EV1813M
• Denon AVR-X3800H with Dirac
• Buckeye Amps Hypex NC502MP 4-Channel amp (powering the R6 and R3 pair)

I live in Atlanta within driving distance of GIK Acoustics, so I’m planning on buying some panels from them, for example:

TriTrap Corner Bass Traps

I’m thinking of installing:

• Two TriTraps stacked in the front left corner
• Two TriTraps stacked in the front right corner
• One 2’x4’ 244 behind the front left speaker
• One 2’x4’ 244 behind the front right speaker
• Two 2’x4’ 244s on the ceiling between the front speakers and seating
• Two 2’x4’ 244s on the right side wall

This is all new to me so if there’s any recommendations on what to buy and where to put it I’d greatly appreciate it. Thank you.

I like these guys. Not only art panels; they have solid color, raw fiberglass panels, etc.
But if GIK is that close you might save on shipping.

What are you trying to fix? It's hard to tell from the photos. Speaker placement looks, intense. Do you have only one MLP?

You might get away with 2’x 2’ panels behind your stand mounts. I use them behind towers because I didn’t want to deal with the outlets. If you see where your cancellation from the rear wall is happening you can use their range limiters to keep from sucking too much treble out of the room. I had good luck with the GIK 7.5” 2’ x 2’. I have the 5.5” 2’x4’ 244 panels on my back wall but you don’t have one. Corners worked good for Tri traps for me, I played bass heavy music and walked around the room before any treatment, I used to have a corner where things piled up but it’s much better now. Music City Acoustics in Nashville also makes nice stuff. I just added 2 of their 5” panels in my bedroom, a little cheaper than GIK after shipping (you can skip the shipping so GIK should come in a touch less). I don’t have any rooms where I can pull the speakers way out from the walls and I find close placement with a panel behind works pretty good for me.

The Music City panels I just got

I did my basement one or two pieces at a time so multiple dealings with GIK. Music City showed better attention to detail and overall feeling of better quality, in my opinion,

Thats a nice space you have there!

Yes, it's just me 99% of the time.

You should read a few articles on ASR member @Bjorn 's website: Lyd & Akustik. Click on "Learning" and there are a few nice articles in there.

First thing I would do is get the L/R off the entertainment center and put them on stands or wall mount them.

Wow - your room is amazing!

How do you like the Amplitude Corner Bass Traps? I was looking at the TriTrap Corner Bass Traps, but am also considering the Amplitudes.

I’ll check out Music City Acoustics. Just curious, what specifically demonstrated their better attention to detail and quality?

 

[Pareto Pragmatic]

Nice! I bet that is very immersive.

Measurements will help get you more specific suggestions, as you might expect.

I would consider the following:

Speakers on stands. For one thing to get them higher up.

Treatment on the screen wall, likely dark/black for movie playback.

Treat the right wall, given the stairs likely create an imbalance in reflections. Maybe left too? I'm not sure how those stairs will affect things from that side.

Add ceiling treatment in front of the HVAC tunnel. Maybe further out as well, middle between screen and seat.

I'd leave the back part alone, you have enough stuff in there to diffract things pretty well.

Enjoy!

Thanks! I like the design on the Amplitude corner traps but I didn’t choose them my wife did. Engaging her in the decision making process was good for me. How much the diffusion helps is an unknown to me but things sound really good in that room.

Music City attention to detail and quality perceived differences that I noticed right away were very taught fabric with nice folds and attention to detail. GIK while the same GOM fabric lays flat and looks fine mounted to the wall the fabric moves around much more and the folds at the edges are sloppy in comparison. I’ve had a GIK order come with GIK badge on one panel and no badge on the other, those Tri corner traps were ordered a different color (GIK gave me a discount after the fact), and I had one panel with a loose internal range limiter just to lay out everything. GIK has been good on the back end but almost every order has had some error. The Music City packaging of all the parts, the stickers, the very detailed instructions, the type of standard (free) mounting hardware, and the thank you note while minor concerning the function were all nice touches. Music City are heavier but that doesn't mean they work better, they also use different measuring standards for absorption ratings with GIK seeming to get a little more out of the same size package. The GIK frames are thinner so that’s some of it, stuffing is probably not the same either. I went with Music City just to try and because after shipping it was a little less expensive, glad I did though they thanked me and I like that and zero errors which is nice.

If you don’t go with stands for your L/R (they look nice where they are but stands look nice too) I would get the front edge of all 3 maybe an inch proud of your furniture piece. You could probably do a 2’x 4’ panel sideways behind the TV and get the back wall SBIR for your front 3 with one panel (I can’t tell how the TV is mounted so that might not work).
