In Reply to: RE: Seeking suggestions on 100 Hz 10+ dB attenuation (long) posted by lochrider on March 21, 2021 at 08:35:09
It's relatively old technology, but I've experienced its use to great effect..... Far better than any active EQ can achieve......

Wow, $1100 a pair! I have a roll of left over carpet from finishing our basement. Maybe I'll try that ;-) Just kidding, but isn't there a cheaper DIY corner bass trap?
Thanks for the suggestion, but the room has fully treated ASC tube traps from 12-inchers to 20-inchers, floor to ceiling, in corners and center front wall. They work great and have made music clear to hear.
Doesn't sound like they are currently trapping your offending frequency!

Some people like a drier acoustic environment and some people like a wetter one. But aside from that basic preference, the number one reason why some heavily treated rooms sound bad is an imbalance in the amount of absorption in different frequency ranges, almost always an excess of high frequency absorption. For example, a good recording studio control room will have a flat RT60 vs. frequency. It will sound drier than most audiophiles prefer, but it will sound balanced. Whereas a lot of home theater demo rooms I've been in use only high frequency wall treatments that make the room sound dead but muddy/boomy at the same time.
My biggest pet peeve is walking into a room where an expensive system resides but there has been no attempt to control obvious slap echoes. It happens more than it should. There ought to be a law... :)
Doesn't surprise........
Too much is never enough
The other fun part of the story was the guy whose room had way too much treatment was a professional musician.
I've tried to talk people out of turning a VERY heavily treated space into a listeining area.
some liveness is good but must be done by ear. \
Pro musician MAY have been 'calibrated' to a dull listening space?
Too much is never enough
He was first oboist in Washington National Symphony. Maybe he was deaf from all the high volume sound. Who nose?
I have several 2ft x 4ft panel traps that I built into the room design so they don't visually stand out. Two of them on the ceiling tuned to 70 Hz effectively killed the main floor to ceiling mode. They are relatively easy to build, with instructions and calculators available around the web.
You may want to try re-arranging them, or somewhat different products.... Just to see how much impact this has on the room sound.
