My goal was to assemble a very simplistic PC based system that had some serious bang for the buck. The Hegel while hard to find used and not particularly cheap is three components and two sets of IC's in one. The Maggies and Rel subs make for a truly full range setup for a really reasonable price. I posted before and after graphs for reference the largest step forward was had through optimizing the multi-sub set up. The LF response below about 100Hz could be made a flatter but I prefer the subs turned up just a bit.
