Re: Bass traps for asymmetrical set-up in L-shaped apartment?

So I got some R40 pink insulation 11"x24"x48" and have been experimenting a bit with it in the right corner. It's going to require some cutting and/or squishing to fit it into my triangle, but I...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

I don't mind you giving me a hard time, especially since you're providing so much useful information :T and I obviously don't know what I'm talking about. :dontknow:

I didn't really understand...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

I was at Home Depot last night pricing things out and I don't think it's going to be any cheaper to use pink insulation. In fact I think it might be more expensive and more complicated.

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

I get it now. I was going back to my original thoughts about a Superchunk trap with a 24" face and 16" depth. The other drawing I did was based on a Studiotips Corner Absorber, which has more depth....

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

I just noticed you added a picture to your post. I guess we are on the same page.

I'm up for cheaper and more effective, but I'm not sure I'm following you. Are you suggesting something like this?

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

So there's seems to be some consensus that a Superchunk in the right corner is a good start, but the effectiveness of any further treatment of the wall beside the right speaker is still questionable....

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

I did some more testing last night, and I'm starting to understand how to use the Impulse measurements to identify the various reflection points. By taking some measurements and experimenting with a...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

Doing a full range sweep seems to have made a big difference and I think I'm getting a proper looking ETC's now. I think had also read that it was easier to limit the sweeps to 300Hz, so I guess...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

Here's a couple new graphs with the distance from the mic to speaker baffle marked on them. I've also attached the mdat. I tried to measure as accurately as I could with the Bosch DLR130 laser...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

Sorry, but I just noticed the date on the mdat I posted was Aug 23rd. I meant to upload the file from the 25th, but was rushing before I went to work. I'll redo the ETC's tonight and post the graphs...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

Thanks again for all detailed info. A lot of it is going over my head, but some it is starting to sink in. I will take a more accurate measurement when I get home from work. My speakers look like...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

Here's the mdat file from last night. I hope that helps, and I can also try to alter the graphs tonight when I'm home from work. The distance from the tweeters to the mic is 8' 8" as measured with...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

I ran some more tests tonight and here are some waterfalls and ETCs for each speaker. I'm trying to figure out how to interpret the results, and I'm not sure if I did them correctly, so right now...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

Thanks for the clarification. You're probably right about it being an exercise in frustration, but I have the gear to do the testing and I am keen to understand what the sound "looks" like in my room.

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

Okay, I've been trying to figure out how to send the test signal from REW to each speaker separately and I'm stumped. I've been reading the help files and searching the forums, and can't find any...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

Thanks, I'll give it a try tonight. I have done some measurements with REW and still have tape all over my floor marking the various measuring positions. Instead of hanging a plumb bob from the...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

Thanks again for all the info. I had to do some searching to find out what an ETC was, but figured it out and understand now that it's part of the Impulse Response. So what you're saying is I should...

I am very appreciative of Brian's assistance, and I certainly hope I didn't say anything that would suggest otherwise. Unfortunately, this is not a dedicated listening room or home studio, so I do...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

That would be much easier, and not too obtrusive. I really don't want to fill the corner with a superchunk, but would be willing to put a tri-corner in the upper right, and a 2'x4' panel on the right...

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

Re: Bass traps for asymmetrical set-up in L-shaped apartment?

Thanks for your response. Actually, my first thought was to fill that right corner with a SuperChunk or Studiotips Corner Absorber trap, but I thought it might be better to distribute the absorption...

Bass traps for asymmetrical set-up in L-shaped apartment?

Hi,

This is my first post here and I'm hoping to get some advice regarding bass traps or acoustic treatments for my apartment. It's a rented space, and it's not very big, so I want them to be as...
