Purchased two of these to go with a pair of SRM450V2s.
One failed second time out [but replaced and delivered by Andertons within an hour and a half - great customer service!!!]. The 1000W power amp rating stated is misleading - 500W is a truer figure - and, whilst they kick out adequate bottom end for most music, I'd not risk them on loud bass heavy stuff as they seem to overload fairly quickly.
Integrate well with SRM450 V2s.
Needs two people to lift them comfortably, but have good handles, and are not excessively heavy by the standards of many sub woofers.
Wiring them up as shown in manual does work, but running them from the outputs of the SRM450s does the business.
I'd give them 4 stars if the reliability issue proves to be bad luck rather than a design problem.
