Bought this sub to to go along with my cms 65s and tighten up the bottom in my home studio, and it performs amazingly well! I feel like I have to re-mix everything I've recorded. I do a lot of keyboard playing with my Yamaha motif and thees8027e sound quality of instruments like the accordion cello bass and even piano have been mouthwatering! Shout out to my man Marcos Sanchez ext. (1331) who never steers me wrong!
