SVS SB-2000 Pro

“I'm using a SVS SB-2000 (+SVS SB-1000) in a very well sealed small room and due to it I can play down to \~4Hz flat, F10 at \~2.2Hz (depending on open windows/doors in the house). During the compression tests got the mic knocked over, so I consider it enough output, even if it's not reference level in the Infrasonics haha Frequency Response at MLP (no smoothing): [https://i.imgur.com/Tw83Nl3.png](https://i.imgur.com/Tw83Nl3.png) You can feel the vibrations and the pressure buildup, but you don't really hear anything. The best way I can describe Infrasonics is the feeling you get when something bad happens and breathing gets a bit hard and you start breathing manually and your body goes into fight or flight mode. I had a friend over and we've been talking while we started watching Kaiju No.8, which goes down in the single digits in the beginning and he instantly got locked in haha. I wanted to know how deep/loud it was, so I measured at the same output level afterwards with the same scene - Playback had peaks of up to 107dB and played down to 3Hz during listening in my room: * SPL Log: [https://www.audiosciencereview.com/forum/index.php?attachments/1742727217072-png.438460/](https://www.audiosciencereview.com/forum/index.php?attachments/1742727217072-png.438460/) * RTA (doesn't show peaks well): [https://www.audiosciencereview.com/forum/index.php?attachments/1742727320929-png.438461/](https://www.audiosciencereview.com/forum/index.php?attachments/1742727320929-png.438461/) Hope this answers what you've been looking for :)”
