Velodyne DD-18 vs Martin Logan BF 12”


Looking to get a sub.  Large room - 2 story family room.  I have Sonus Faber Venere 1.5’s

looking at the Velodyne DD-18 and the Martin Logan Balanced Force 12” and Decent i

which would be best for the room and to complement my speakers?   

Music over home theater.  

Thanks.

Get the DD-18.

I have a VERY large room and the DD-18 loads the entire room and makes the home theater sound incredible.
Bigger is better and lower distortion. Integration with the room and speakers is always a bit of a pitb.

Built in calibration systems matter a great deal, more so than motors and amps in many cases.

Best,

A friend has a DD 18 and I think it's one of the best subs I have ever heard.
