Price is currently $749 everywhere.
I also considered this subwoofer with the KEF Kube 8b as a musical subwoofer for 2.1 duties, due to both having basic DSP corrections built-in & reported performance with music.
The B&W ASW608 actually out-does the Kube 8b with DSP options, as it has one more extra adjustment switch.
The ASW608 has 2x DSP-switches, “Bass-extension” & “EQ”.
From Manual:
The BASS EXTENSION switch offers three options of subwoofer bass extension. Position A gives the greatest extension and position C gives the least extension. Position B provides a compromise setting. If the system is to be used at very high volume levels or in a large listening room, restricting the bass extension by selecting either B or C may help ensure that the subwoofer is not asked to exceed its performance limits. In most situations the BASS EXTENSION switch should be left in position A.
The EQ switch alters the subwoofer bass roll-off alignment. The bass you hear is a combination of the subwoofer plus the effects of the room and you should choose the position that best complements your room and the location of the subwoofer.
Position A gives a “drier” alignment, more suited to placing the subwoofer in a corner or compensating for a resonant room. Position B is suited to a less resonant room acoustic and use away from a corner.

Notes: The manual is very detailed in setup information and will help to best integrate the subwoofer to main speakers.

Good only for music, would avoid for movies because SVS would have something better at a similar price.
