active room nuetralizer???

...and just to add to the mix of things one can do, I ran into this tidbit.  Since I like to 'run the room' eq'd for flat response as much as practical, this seemed a tempting approach...

Enlist the room in fixing itself.  A simplification, sure, but interesting.  Might minimize the amount of 'stuff' needed to tame the space.

Just a suggestion...

...appealed to me as it would seem to be an easyish thing to DIY....I have a lot of other things I'd drop 3K$ on these days...

erik ,
I mispoke earlier,my post about my slap echo and using traps on the ceiling .I meant absorbing panels on the rafters ,I do not have a problem with panels and my wife is very cool .I was asking about people who are not able to run panels. Interesting info....

@erik_squires - sorry to hijack the OP, but I have a question on the Bag End. Have you actually used the Bag End E-Traps? I have a pretty good room and do not have any major bass ringing. However, I do have a huge hole around 80hz where bass just falls out (this is a room node where I’m sitting). The Double-Bass Array (DBA) configuration that is popular in Germany would probably solve my problem, but it is just not practical for me to do in my room. I have looked at general broadband absorption, Helmholtz resonators, membrane panels from GIK, etc. I tried a pair of GIK full Soffit bass traps, but I didn’t like them -- they seemed to suck all the life/excitement out of the room. I am curious about the flex-range limiter panel on their monster bass traps and the tuned membrane. I haven’t yet looked into spending money on this problem (maybe next year). My initial thoughts were to try the flex-range-limiter option. However, this Bag End E-Trap looks really effective. There is one review where the user was able to restore a big dip in the bass area. Other feedback indicates the Bag End cannot restore big dips - it can only reduce bass peaks/ringing. Do you have any experience with this?

@auxinput I'm taking this to another thread so we don't stomp on the OP's questions. :)
