Con trampa:
Here are waterfall plots taken in my room at mix position with two
AVAA C20 units placed in opposite corners (front right, left rear).
The AVAAs are turned off and on, obviously.
And here's the frequency response (off/on overlaid on the same plot):
I don't know how many unicorns PSI Audio had to milk to fill up these little 29 lb boxes full of magic, but within 5 minutes of putting two of these loaners from Warren into the corners of my room, I was begging Warren to take my money so I wouldn't have to send them back!
Riffing off of what Warren already stated above, these suckers
take the ...OOOOMMMMmmmmmmnnnnnnn out of your room, so that you can clearly hear the BOOM. But they also reduce "bass-suck," the loss of bass energy due to room-mode cancellations. (Room resonances can TAKE AWAY desired bass energy as much as they can add unwanted bass energy, as is evident in the waterfall plots above.)
Unless you already have a significant portion of your room's physical volume filled with
Bass trapping, I doubt you'll find a more efficient solution for reducing low-end resonances than the
AVAA C20. With that said, the C20 isn't going to magically fix a crap-sounding room, so step one should be to install passive treatment first, before investing in the
AVAA C20.
