Thanks for the info Mike, that clarifies things. I recently purchased a pair of your Force subs and love them.
I received a question on another board about the crossover settings and the ability to keep the sub from muddying the midrange. This is one of the most persuasive attributes of your subs, even when compared to the REL Strata sub. A comparison I found valuable was to chart their rolloffs at maximum/lowest hz settings, something you may want to add to your site. (I think I did this right ... frequency doubling with each octave).
FORCE: -24db @ 70hz, -48db @ 140hz
STRATA: -12 @ 44hz, -24db @ 88hz, -36db @ 176hz, -48db @ 252hz
Even though the REL has a lower crossover minimum xover freq. (22hz), it can't get out of the way of the midrange with only a 12db/oct. slope the way the Force can with its dual xovers!
Thanks for the great subs!
