Hi there. My first post on this forum. :b I just ordered four DPL-12 from Adire. They will go into a 280L (10 cubic feet) sealed enclosure. Drivers will be wired in series and connected in paralell, giving a 4 ohm load. Sub is going to be used for both music and HT. Now I am looking for a decent plateamp. Wanted to know what users of the Keiga KGND-52100 subwoofer amplifier think of it. Any reliablity problems or anything I should be worried about? The Hypex HS-500 is also an option. Any other plateamps I should consider? I live in Europe so it must be switchable to 230V. I would like to keep things simple so an external pro-amp is not an option. Thanks!
