Yes, very very good for the money imo you'd have to pay 3x the price to get an equal speaker at 'retail'. Of course they have a full setup in the shop so dont need to take my word for it. In any case if you know how to operate wood glue and a spray can, diy is slightly very simple :P

In any case here is an independent review (same site has reviewed some of the cheaper models also)
