  • Type R amps has always been a target of mine to have for a long time and now that I got one, it really exceeded all my expectations. Top level amp. Power is unbelievable. Perfect sub to pair would be an R-Series too. Will buy one hopefully next month.

  • After hours of use, its amazing that it's still really cool even with it's location a little bit isolated. You can really hear the difference the sub when you pair it with a cheap amp and much more expensive amp like this one. It's clean, louder, and really much better than before. Really powerful too
