Did you used to use any channel EQ on the CM's?

That might be coloring what you are hearing out of the G70's outputs. You were probably boosting the lows massively to compensate for the lack on the CM's, and probably doing it with the G70's EQ too, weren't you?

I would switch off ALL the EQ in the G70, and just see what the Compact sounds like OOTB. No point doing anything until you HAVE to

Every time I play through my friends L1 system, I have to LOWER the bass EQ on my G70! Those subs always seem a bit hyped in the 200Hz range and downwards. To be honest, after setting my G70's EQ so that it sounds good through a decent pair of nearfields (Mackie HR824), I always feel that the Bose's sound like someone engaged a massive 'smile' EQ, basses get pushed forward, the sound gets brittle, and much of the midrange 'warmth' disappears. It always strikes me as redundant that you have to apply quite a bit of EQ to simply negate the natural EQ of the system and get back to 'flat'...

I hope that it works out for you... the form factor looks amazing. Look forward to your next report.
