I've got a Velodyne VA1012X sub with a 10 inch front firing woofer and a 12 inch down firing radiator. Amp is rated at 100 watts with a peak load of 250 watts possible. It is a very musical sub, very tight, controlled bass. With a little moving around of of my front speakers (Pinnacle Classic Gold Reference), and playing with the crossovers on the 1050, I think I now have a pretty seamless integration. It's amazing what the 1050 can do when hooked up properly.
