Looking to upgrade my sub, and wondered what others have (up to £500) which they would recommend. BK xxls400 is tempting, but demoing could be an issue. Was thinking also of the AE Neo V2 sub, from theWHF review it sounds like what I am after. I would much rather a good quality bass and lose a bit of low end. So before I go demoing and arranging the trips, thought I would see what others have and are happy with to help me draw up my list of potential candidates.
