DQ-10's

I picked up some DQ-10's in hopes of building a better system. I had read a lot of good things about them on the web and they fit into my price range (400) plus it would give me something to screw with. I really liked the sound except for mid and low bass. I found a Dalquist crossover and hooked it up to a cheap Velodyne Sub. Low base good enough for me, but mid bass still seems weak and distant. Would a 200 watt amp make a big difference? I am currently running a Robertson Audio 4010 which I think only has 75 a side. I like the amp, but was wondering if a 200 watt Rotel get the midbase back. Currently the sound is great on a song like Treetop Flyer, but can start to fall apart on harder faster music. Snare drums seem a bit distant and muffled. Music is from a PC via optical to a Rotel 1098 that does all the DA conversion. Music is in .wav format uncompressed. Not much disposible audio income.
