It's not that the subs have any new and sudden issues; not at all, they are still doing a wonderful job. What I meant to say is that with all of this new found power, the three woofers in each T have a huge increase in output and as such, they are really quite 'present' vs. when they were being fed by an amp with significantly less output. As such, the front two mains are really rounding out the lower range and making the two subs blend more evenly. I guess its like adding in two more subs to the room which would increase total low end output and make it far more even.
The 240 volt input to the M1's just elevated this to a whole new game. It's not even close to the 120 volt set up. It was well worth the effort to make the installation.
