It would be interesting to perform a square wave analysis of the HT3s and the Largers. I'd bet the woofers in the HT3s are simply faster. If that's the case, digital room correction cannot change that. I also wonder about Qs of these speakers and what the effect of Q is on integration. For instance, is it easier to integrate a sub having a Q that's about the same as the speaker? While Largers are designed to be adjustable in Q, that adjustability is limited and likely over a small range. Anyone know what the Q of the HT3s is?
I think that DRC, while beneficial, has its limits -- it can't change the physics under which speakers operate. Perhaps that's the case here. Another limit to DRC is its total reliance on linear systems -- any non-linear parameter (such as the transient response of a woofer) cannot be modified by DRC. In fact, it can't even be modeled by DRC.
