after reading audio forums for the past month with some frequency, it seems as though smaller subs have a better performance at higher frequencies (~80hz).
A recent thread over at the Hsu site was comparing the LFM-1 (based on the STF-3) and the STF-2. The user noted the LFM-1 went deeper and louder, but didn't have the same kick at the higher frequencies as the STF-2. Now, this could just mean HSU is better, but the consensus seemed to be that the 10" woofer was superior to the 12" woofer for those frequencies ranges.

So, I was wondering if anyone had tried using a smaller sub, such as the LFM-2 or the STF-1 wired up to their mains, setting the speakers to small with a crossover of 40hz or 60hz, and then having a larger sub connected to the LFE. In essence, this would have the main sub doing the <60hz work. The small sub doing the 60hz to 80hz work, and the main speakers doing the 80hz+ work. Comments?
