Never but never use subwoofers with magnepan only the dwm panels from magnepan . You must use a power amp like krell the ksa 250, cello duet,viola thats kind of stuff. Never tubes!!
I use the fast KEF KC62 sub with my LRS+. I think I cut over at 50 Hz. My friend who is a musician, recording engineer, and a golden ears heard my office system and said 2 things.
- Why would you use anything but the LRS+ in a small room like mine. Other speakers who be a waste due to the room size.
- The sub integration with the LRS+ and KC62 was seamless.
