I'm very happy with these so far, we have used them twice this weekend at two 150 capacity dance music events. Running two subs on a channel each off a inuke NU6000DSP, with the sub filtered from 35hz - 110hz feeding around 800 watts into each box and they sound very good. Very nice, deep, warm bass & plenty loud enough too.
The wheel hole spacing is 75mm x 45mm and cannot accept the standard thomann wheel which I ordered.
To move around they are manageable, don't feel that heavy on short runs, with two person lifts these are a breeze.
Workmanship is good, will order covers on next purchase as paint is not that thick to protect against transit damage.
All in all an amazing sub for the money, very good performance, will be buying two more shortly. Hopefully I can give another positive update in 12 months time.
