Awesome sub
Bought this to go with my other KW181 and I love it! Seriously powerful sub and sounds even better when you couple them together to squeeze out a few extra db!

Bought one of these to go with 2 x K12 speakers. What an incredible speaker, i have had so many people comment on the bass the system is putting out and i actually had plates falling off my shelf at home when trying it out the first time. You can really feel the bass and with deep set it is just incredible. Setting the K12 tops to external sub gives extra headroom on those giving a good all round sound system. Having them on castors also gives you the benefit of using the KW181 as a trolley to put your K12's on and wheel them in the venue. If you are in a small room (50 people size or a pub) i would leave the bass bin at home otherwise you might be shaking the bottles and glasses off the bar ( honestly)

A quality bit of kit!!
Well, what can I say apart from WOW. I paired up one of these with two K12's and the sound quality is amazing. One quick flick to put the sub into deep mode and it just comes alive even more. Its a heavy unit but has castors on it which don't rattle with the vibrations when used. A screw thread for the pole to attached your tops to makes it nice and secure. Also make sure you but the bag for this sub to keep it clean and damage free - which has a velcro panel to keep the panel protected. For a sub with this much power, the size is great. small enough to be discreet but powerful enough to make enough rumble.
