Hi, can any of you experts help out a newbie please. Does anyone know much about the B&W ASW!000 sub. I have been offered a used one for £200 and wondered what you guys thought?? Is it good value or too old and too big and too much £ for my set up??? Marantz SR5200, Pioneer DV535, Arcam CD72, B&W 602S3's,B&W CDMCSE, Mission 77ds rears.
