What is the product? Are we supposed to guess?
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.
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.
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.

Give the Room Tunes Echo Tunes a try sometime. You’ll be singing a different tune. As it were. No one ever said Bass Traps did anything room echo.
I use the Bybee Room Neutralizers (non-powered) in my room- a set of 8 does the job nicely. The DO make the room boundaries disappear sonically, but are not going to fix nulls, peaks, and other issues. These need to be addressed first and then when the sound quality in the room is relatively even, the Room Neutralizers will take it the rest of the way. Good Luck!
There’s a bunch of active and passive room "neutralizers" including but not limited to SteinMusic Harmonizer, tiny little bowl resonators of various manufacture, Lessloss Blackbody, 1 GHz Ultra Tweeters, Sugar Cubes from the tiny little bowl guy, Marigo VTS Dots for walls and windows, tiny crystals for room walls from Acoustic Revive, Schumann Frequency Generators of various manufacture primarily Acoustic Revive and Mpingo disc.
...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...
@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?
