Hi, I have a chance to visit PSI audio, they are switzerland speaker manufacture. I listened to there system and also at some other listening of Illusonic and Weiss (all swiss), and realize that they are using an Active Bass Trap. In my opinion, It works very well, the installation is also very simple. What do you think about this? The price is about $2.3k/each and you will need at least 2 for a room. The best will be 8, I guess. Have a nice day. Son Vu |

Hi silversong,
Welcome to the forum and thanks for the cool product video.
Funny, a few days ago I was dining alfresco and the road noise was terrible. I was joking about something like an active noise cancellation system.
So OK, this is NOT a noise cancellation system but how COOL IS IT! Yeah, my old electrical engineer colleague Gus was apparently right as he often said "All it takes is MONEY!"
To be fair, this forum is hosted by Ethan of Real Traps for the benefit of DIY builders who can't afford commercial products. We often talk about competitors products so I don't want to say this is not allowed but just to put it in perspective. Who knows, maybe Ethan will come out with his own active absorber?
Cheers,
Rock

Hello....im just a musician so limited on any technical advice, but thanks for drawing my attention to this product it looks for a interesting read, ive just read the sound on sound review and apart from the price tag and the fact you would still need other treatments to go along with these it seams to say well about it. If your already considering this as an option and have the funds available, why not. I think its a big personal choice for the individual, if i had the choice and i had the money and Ethans shop was just up the road, i would probably just buy a room kit and have an expert do all my room tests to make it the best it possibly could be. But my circumstances prove otherwise, and i am enjoying the process of building my pannels as there is a big amount of satisfaction ....so dont know if that helps you with your purchase......you said in your opinion it works very well, So you have heard a result, I also dont have that as an option, so i must have faith!!....again on the personal choice, i dont think i would be happy with these sitting on the floor and would want to build them into the wall anyway as they would seam messy just sitting there, if things aren't tidy to my eyes I can't concentrate! Happy shopping!

Their documentation says it needs to be used in conjunction with other passive broadband absorption. Seems like it is a complement product, not a replacement or all-in-one product.

Hi,
It will have the same function as Real Trap Bass Trap put in the corner of the room. You will also need other acoustic treatment like absorber panels, diffusor...
According to manual document, the effective area of this one is 1-1.5m, it is like you have a hole in that corner.

Found this comparing 6 MondoTraps (Blue) to 3 of the active traps (Orange). The 6 MondoTraps cost less than 1 of the active traps and appear to be on par and/or out perform the 3 active traps.
Fig.2 Left speaker measured with Room EQ Wizard, no EQ applied, SPL at 1dB/division, frequency range of 10Hz–1kHz: no traps (black trace), six RealTraps MondoTraps (blue), three PSI Audio AVAA C20 traps (orange).

Thank you a lot for all replying. I think that I missed the part of the active bass trap in Ethan's book as well as the above review.
I see no reason to try this one. Or maybe, because it is very simple, so if you need an instant treatment like audio shows, then it may be suitable.

I never used that particular active bass trap, but I've heard it works well. But it's just a bass trap, and all rooms need absorption at the upper bass range, as well as at mid and high frequencies. That active trap is also a lot more expensive than a conventional bass trap. So even if you get that active trap, you'll still need standard absorbers. When the higher cost of diffusion isn't a problem, that's another component to consider.
