active room nuetralizer???

Bag End has a unit that has been reviewed and works as expected, plus Bag End has a very good rep:

Other cool alternatives are to get some Klipsch corner horn speaker cabinets and fill them with fiberglass, stick them in a corner. They work wonders, and can hold plants and lights on top. :D ;D :D

The Bag End units DO work but they are kind of limited in only taking on a couple of room modes. The most comprehensive solution is corner bass traps plus careful EQ.

Hey Erik
Hope your well,
I saw this and was curious.
I am exploring options on my ht room .GIK has done very well for me in my 2:2 room,but my ht room is pretty big with high ceilings bringing alot of slap echo. I will more then likey run some of the big 7" thick traps high (17’ ) along my timberframe main beam,along with traps and other panels on the walls . I guess I was as usual curious about a product like this in an audio applicaton limited to little or no panels.I am aware of the many room treating options,but my knowledge is limited on this type

Hi OleSchool!  I'm doing OK. :)

The thing about items like this is they are kind of limited in application, and require their own care/feeding and power. Given that you live off-grid I wouldn't want to be adding to your power draw any more than you already have. :) OTOH If you were in a small recording studio this type of device would work really well as you probably have 2 primary modes that you absolutely must kill.

What I mean by "limited" is they are tuned to a couple of room modes. They don't just eat all resonances equally. A "neater" (as in less messy) fix is bass traps plus EQ, multiple subs, or bass traps that are built into the walls themselves.

Best,

I hear ya Erik,
I wasn't really leaning towards an app for me.we hear so many times about people not having the ability to use room treatment.And was just curious about there real world effects. as for my ht room slap echo is my foe...
cheers

after the holdiays i will come visit ...

Well, for slap-echo, the Bag End and other similar devices effectiveness is zero. :-)

Slap echoes are too coherent. Bass traps, etc. rely on the energy in the bass collecting in the corners. By sucking the energy out of the corners you eliminate the ringing. But this works because the rooms ring like a bell. If you put your finger anywhere on the rim of the bell it kills the ringing.

The slap echo energy is all in the middle of the wall surfaces and the wavelengths are too short to attempt to do this. Diffusion and absorbers work fabulously though. :) In fact, with the right lighting they may even make your HT seem less cavernous.

Best,


Erik
