I am soon to build a sonosub with the DVC 12” driver. I will use it 80% for home theater and 20% music. Like most here, I like a theater and music with some bass in it. I would not classify myself as discriminating listener. I currently have the Sony SA-WM40 12” 120 watt sub. I plan to use the mono “Sub-Out” output of my Onkyo 595 receiver to feed the amp. I am contemplating purchasing the PE 250 watt plate amp (8 ohm - 180w mono … 4 ohm – 272w mono) or the Crown XLS 402 (8 ohm – 260w stereo/800w bridge mono … 4 ohm – 400w stereo/1,140w bridge mono). It seems to me the power difference and available headroom of the Crown would be a better combination. I realize the DVC 12” is only rated at 600 watts, but it seems the Crown would be idling at this wattage. The power increase is intriguing for my current design plans plus any future upgrades. Additionally, the fact that it is a full range amp gives me some flexibility to use the amp as a stand-alone stereo amp for parties. The PE 250 has some features I do not think I would use, like line level input/outputs; or that my receiver already has, like phase adjustment and crossover. I am leaning towards the Crown. Am I missing something that the PE 250 offers that should change my mind?
