PSI Audio AVAA C214 Active Bass Trap

Your speaker/room interaction is half your sound. You can invest in exceptional electronics and speakers, optimize every component in the signal chain, and still find that bass in your listening room sounds thick, uneven, and hard to resolve — because the room is doing things to the bass frequencies that no upstream component can fix. The PSI Audio AVAA C214 is what you do about that.

The Problem with Passive Bass Treatment

Passive bass traps work by absorbing bass energy in porous materials. To be effective at frequencies below 100Hz, a passive trap needs to be physically large — typically a quarter-wavelength of the target frequency, which at 50Hz means over a meter of depth. Most listening rooms cannot accommodate enough passive treatment to control room modes meaningfully. The result is treatment that helps at higher frequencies and does relatively little at the frequencies that cause the most obvious problems.

The AVAA Approach

The AVAA C214 is an Active Velocity Acoustic Absorber. Instead of physically absorbing bass pressure, it uses a microphone to sense the particle velocity at the room boundary and drives a small loudspeaker to create a counter-pressure that effectively simulates an infinitely absorptive surface. This active approach is three to four times more effective than a passive trap of equivalent size, and it works from 15Hz to 150Hz — the full range of bass problems that affect listening rooms.

Plug it in, place it in a room corner, and let it work. No room modification, no structural treatment. The C214 is self-powered and requires only an AC outlet.

Press Recognition

Love them
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I wear a size 11.5 in ladies shoe and these just barely fit. Butttt after I put lotion on my feet and slipped these on and left them on for about 30 mins. It left my feet really soft! They work great as intended. Would buy again

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned. These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.
