Are you kidding ? I’ve uploaded measurements of what you ask just 15 post behind yours. Its even on the same page...The room is 25m2
It all depends on your needs and strategy. For me it is suitable. I get response to 20Hz (not 100% linear because of the challenging room), the sub is small, beautiful and fits my available space, it adds the needed weight in bass and I’m not even stressing it.
I would not trust that SVS wizard that chooses subs. I could get more output around and below 20Hz if I went with PB-1000 Pro, but it is much bigger and won’t fit where my SB-1000 Pro is right now, and it doesn’t sell in White gloss to match my white R series. Plus I could run into rumble issues with neighbors because of higher output below 20Hz.
As an advice, don’t go dual Sub if you don’t know how to integrate them with a Umik microphone and MSO, or if you don’t have Dirac Bass Control in your system. Oterwise its more harm than good.
Do it if you know, or hire someone who knows.
