I'm aware of damping factors and slew rates affecting tonality when it comes to Amp topology.
You have completely under looked enclosures here, You can not deny science!
2 15" IB drivers in your case Vs a single 12" driver in around 7-8 cubes. You simply can not outlook Hoffman's iron law. Two VERY different setups sir

The lower Q driver has excellent impact up top and sounds much more controlled (tighter) but lacks a little on the bottom end. However compared to a sealed enclosure it is still night and day.

BINGO!
High Qts generally will have smoother tonal characteristics, lower Qts more impact. Qts is also a good indicator of motor strength and how its delivered. Be it a peaky type driver with a short wound coil means it won't have much in the way of massive throw for those big dynamics.
