The FV15HP operated in 1 port mode exhibited very low extension down effectively to the 14-15Hz range anechoic. Due to the servo design and amplifier the top end above 90hz is gradually rolled out on this unit so it can't effectively be used much past 100Hz. The subwoofer shows a good amount of headroom and very good compression performance from 25Hz on up. Exceptionally good. Unfortunately the single 3" port can't cope with the output of the 15" driver and compresses a lot while also contributing a lot of wind noise at the highest output levels. Still overall headroom and low bass extension are very good. The distortion performance is decent but could be better. This sub also exhibits a good damping with no appreciable ringing to be concerned with.
