Let's have a specific thread about subs.... Suppose one were shopping for a subwoofer round the £2500-£3000 mark (for someone as poor as me that's high-end, okay?), what would be a good choice, and just how much of a difference is there between something in that price bracket and something at ~£1600? Obvious possibilities: Velodyne HGS-15 and HGS-18 (Uncle Eric's favourite, I believe), REL Stentor, M&K MX5000. Cheaper possibilities: REL Stadium, M&K MX350, B&W ASW4000. Any more?
