For any "homestudioguy" on a budget, they are GREAT!
Just go easy on the spray adhesive.
(ie save some for the panels )

As Frank, Glenn and Ethan have been "preaching" for years, a well treated room will provide for a reduction in room anomolies that may negatively affect your recording down the road that may NOT be able to be "fixed in the mixed".

You can have the "greatest" equipment and plug-ins in the world but a "bad room" can render it all worthless.
On the Flipside, you can have "OK" equipment in a well-treated room and have a great sounding song.

[QUOTE=bamm;1387335]Are we tired of these threads yet? The truth is, that bass traps make a tremendous difference in a room. I had 10-15db nodes at 80 and 125 and huge decay times. 100% better now.



Hello everyone! I am new to this and this is my first post, so bear with me. I, too, have the same room modes in the bass. I am dealing with a dedicated listening room, not a recording studio, with excellent electronics (McCormick preamp & amp, modded Music Hall SACD, Vandersteen 3ASigs and Subs).

As I have been reading much lately to try to learn more about room acoustics (this includes the oft-referenced books, GIK and Ethan's websites which are full of great info), I have come up with a few questions and would appreciate any help you can throw my way.

1. While I would expect bass traps straddling the corner to reduce modes, won't it also reduce the other bass frequencies as well?

2. I have Vandersteen 2wQ's in the front corners. Attempts to use bass traps over them took the life out of the bass. Corner positions reduced the 40 HZ mode by a couple of dB over positions 1/4 length out from the corner.

The room is 8.5 and 7.5 ft high (you guessed it - a soffit in the rear 6' of the room), 14'7" wide, 20'11" long. Carpetted floor, drywall on 2x6's for walls, drywall on ceiling joists. Two adjacent 3' windows centered on the fron walls.

I bought two backless 4" bass traps and two 2" acoustic panels from ATS early in my research, each 2' x 4'. Recently bought 10 T'Fusors @40 each.

Music listened to is mostly classical with some 60's.

Well, thanks for enduring the long message. The two questions above are what I would like to start with. Just wanted to give you some context.

No, bass traps make the response flatter, by reducing the level of peaks and also nulls. Bass traps also reduce modal ringing. So as more and more bass traps are added to a room, the LF becomes progressively flatter and tighter.

That bass cabinet in the room could be seriously screwing with your low end too, especially if it's not connected to an amp. They'll sympathetically vibrate at the system's (speakers+cabinet) resonant frequency & without an amp connected to damp them, they'll ring & re-radiate that energy back into the room.

Thanks so much for clearing that up. Funny, in all that I have read so far, I have either missed that fact or it is assumed that people that are new to acoustics just somehow know it. NOW, I understand the reason for the emphasis on bass traps!

I am sure to have more questions about all of this as I learn more. For room acoustic treatment, is this the best thread or forum for further questions? I see you and Glenn posting answers and comments A LOT of places.

Again, thanks!

The best place to ask about bass traps is in the Bass Traps area.

BTW, the reason that bass traps both reduce peaks and increase nulls is because they reduce the reflections that cause both.

Not because rockwool can't do a good job for acoustic treatment.
It is because rockwool can harm your healthy badly.
rockwool is banish for causing Lung Cancer.
This is why people are using fiber-glass instead of rockwool now days.
(fiberglass can also caused breathing issue; however, not as horrified as rockwool).
Even though Rockwool works the best.

I sersiously suggesting you guys treated rockwool carefully. Make sure you seal the rockwool with extra glue and multiple layers of materials. It is because rockwool's dust is very small and most likely will leak and spread out badly. They can even go through your skin and bites.

The Regular Curtains and cutton will not able to lock the rockwool's dust beacuse their pores are too big to lock rockwool.

Rock wool doesn't mean asbestos, dude. And even if it freaks you out, there's not one of us who hasn't been exposed to asbestos in one way or another. It's just too prevalent. It's everywhere.

Chill brother. Life goes on...then it ends, rock wool or no rock wool.
