Got my 600 working they way I want it.

Wow, that is astonishing (bass - Reactor vs Nautilus 802).
Did you miss anything (soundwise) compared to the Nautilus (apart from stereo)?

To be fair though I reckon the Nautilus would have sounded amazing if I had listened to them much louder. I had 2x 200w monoblocs running each one but I just didn’t listed loud enough to get the woofers moving to get the bass out. They used these in Abbey Road recording studio. With the Reactor i can get the nice low bass at low volume. I’ve got Katie Melua - 9 Million Bicycles in Beijing on just now at 35/100 volume and the side drivers on the Reactor are going nuts even at such low volume. Sounds fantastic. I love this thing. 

Here’s them at Abbey Road.
