The Rythmik D15SE is new, purchased 1 month ago and is perfect in high gloss piano black and digs deep, flat to below 14 hertz! I paid $1049 plus $90 shipping but sub is just too big for my den- 18” wide, 18” deep, 24” high. After sale, I will purchase the smaller Rythmik F12.
If you know Rythmik, rythmikaudio.com, you know these are regarded among the best!
I am in Vero Beach, FL 32963 but will drive 2 hours to meet you or deliver to your home including a REW set-up.
