B&W AS4500 which they don't sell. 450 watt class D built in amp, lok like a piece of furniture. I use it for my home theature nosubs in my two channel system. Has a 15" woofer pported down to the floor. My kids call it feel avision because it shakes the house with distorting. If you can go a couple of grand check out B&W the sub that replaced mine has the same 15" speaker smaller cabinet and a 1000 watt class D amp. No disrespect but velodyne which is popular isn't even close. B&W will also helpp you with the wife factor as they look sharp.
