I understand and agree with what you're saying and have done a fair bit of experimenting and building myself. What about using low density fiberglass batts and leaving them in the plastic bags? Create a depth of about 12" to 17" in corners or floor to ceiling whole wall. You need to measure!

really one of the best home theater channel, keep up the good work and hope you get more views like you deserve soon

Thank you, thats really a nice comment. As I mentioned to another, I've been professionally designing theaters for a short while now and consulting for far longer. I am told on a regular basis by leading professionals that I know more than most of the professionals who do this for a living and so I decided that it was only fair to share that how I can. Most of my projects are with folks that require utmost discretion, so I can't share those projects much, but I can share what I am doing for myself. I can share what I know and what we do on real projects in ways that work for the average person.

Up there with home theatre gurus as the best on KZread. Amazing content!

I appreciate that. Please keep in mind that I am a professional home theater designer/engineer. I am a senior engineer for PMI (Anthony Grimani). I am lucky to be working on many projects whose total project cost most home theater designers/installers would only dream to work on. I use this channel as a way to share my knowledge and experience that helps the masses and not just the ultra wealthy. I don't think there are many if any other channels with that kind of background. I am not just an enthusiast.

The Real Acoustix panels are just sealed absorbers. Completely different to VPR panels like the Modex which aren't sealed. The Modex use the insulation as a spring. Sealed absorbers use the air as the spring. Many ways to do both which can affect performance drastically

I appreciate you putting up information about this company's products... however you really need to watch Eric Valentine's experience with metal panel absorbers. quite elucidating. you really can't tell what's happening unless you're taking measurements. LOTS of them.

Interesting video! At 50Hz, wouldn't you use multisub to handle that range? Like at a certain point isn't it easier to just use four subwoofers and do modal manipulation to get things squared away down there? When does it make sense to add such low frequency absorption?

looks lite its covered with black velvet but I'm assuming that its AT cloth to allow full reflection of high frequencies?

It's AT suede. The front is steel with an AT fabric so it is going to mostly reflect HF's yes.

I hope you are able to walk through measurements of the before and after.

I absolutely will. I have some measurements I took, but I didn't take them with that intention and I am not totally convinced they are correct. This is a big bass trap but it is only in the one corner and really would only be working on one set of modes. I want to get the other subwoofer into the room and then do a measurement with it in the room vs out of the room.

@@PoesAcoustics Great! I hope to learn how you recognize problem areas and how you addressed them.

Do you have the BassMod traps on just the rear 2 corners, or do you have them on all 4 corners of the room?

@PoesAcoustics

There are doors in two of the corners so it was not possible to put them in four corners. Interestingly, Geddes found that it is not necessary to place bass traps in all corners, that what you do in one corner or on one wall is replicated by half on the other. So yes, if you put corner traps in every corner, you get the benefit of a very large area of absorption. But if you do just half, you get the same benefit, but half the area. In part this is why I did an 8' bass trap.

Everyone says don't sit in a pressure max area. If you arer using multi sub and equalization does that still ring true? Why? What's the science behind it.

@PoesAcoustics

Жыл бұрын

Well the pressure maximum is usually the site of a big null. So that is why its said. No with multisub that isn't true as long as multisub has done a good job addressing the modal issue. In theory a good 4 sub setup optimized correctly will give a large listening area that has a smooth response with no peaks or nulls. In practice it doesn't always work out and sometimes optimizing seat locations can help with that.

Real Acoustix is right here in Utah (where I live) up the way a bit in Ogden. But as for your own home theater, since it's such a small location for 'Bass Trapping', I only have to say about it.... MEASUREMENTS, or it DIDN'T HAPPEN!!! hahaha! Can you show its effectiveness in REW or something similar? Can't remember if you said you measured your room before any treatment.

@PoesAcoustics

Жыл бұрын

I did but in hind sight it wasn't very comparable other than for looking at RT60. I measured the room with nothing mounted and then a year went by and I measured again with stuff mounted, but...With different speakers in different locations. I do have a before and after measurement. I didn't take them with the intent of it being before and after, so it's not the most scientific, but they were taken less than a week apart. I plan to remove the bass trap and do a "before" measurement, and then add it back and do an after. The before and after I have shows a big difference, but I worry that more changed between those two than I realized.

@@PoesAcoustics ok cool looking forward to see that video then. My room measures .15 which is way on lower side but I don't have much absorption on side/back walls and makes me wonder if simply taking RT60 in REW at MLP is all it takes to see the real RT60 for a room.

I have a few videos to catch up on. I’m looking forward to this. Just here to leave a comment for the algorithm. Ill let you know what I think once I binge watch.
