Room Treatment


I have been going back and forth regarding room treatment. Two weeks ago I tried ASC 16" round tube traps in the front corner...the results were minimum. Considering I don't have any room treatment I expected more! Now I'm trying to figure out if my room needs room treatment...20' x 24', carpeted, 8' ceilings. I played several songs and walked around my room and noticed excess bass in the front left corner. Looking for some advice regarding room treatment.

That's a good sized room; have you tried clapping your hands in the center of the room to hear how "live" it sounds? Does the bass sound tight or is it boomy? You may find that you need some absorption or diffusion panels.

It's good that you've got the speakers away from the walls, but 2 vertical absorption panels behind the spkrs and 2 on side walls would benefit, just as Ghosthouse has suggested.
Yup, Ric...One 244 panel behind each speaker. You can always do just a couple things at a time. I thought those 2 bass trap panels alone gave a big chunk of the improvement I got.

By they way, that's a beautiful finish on your speakers.
Did you rotate the ASC 16" bass traps? ASC designs them so half is reflective and the other half absorbent. A friend of mine uses them and spins them according to the music he is listening to because they have a huge effect on the sound stage.
Hevac1,

No,I didn't rotate them. Based on the dimensions of my room I was told to place them with the seem facing the corner. My room is L-shaped and I'm trying to figure out if I will benefit from bass traps. What are bass traps designed to accomplish?
As with most people who go down the room treatment road, they neglect the ceiling. Often because there may be lighting that cannot be blocked. However if that is not the case, some treatment can be very effective and not very expensive. I have seen simple 'wave' canopies used to great effect. For some ideas, check out the Armstrong acoustical product site, they give a view of what might be possible. Another treatment approach is the use of grid ceilings with drop in panels of all kinds, wood scatter and slot patterns working the best. Some of the companies that market these are still in business. Last thought, in most new concert halls they have adopted a deflector ceiling approach which really improves the overall acoustics of the hall. So, take a clue from that. 'Tuning' the room will provide endless rewards, more so then changing equipment.
