I also tried numerous sub set ups and was never quite satisfied with the synergy to the main speakers. I'm sure there are Agon members much smarter than I that figure out the correct components, set up....
I went a different route. I had a pair of 3-way speakers built with Usher drivers. Uses one 8 inch woofer. Overall very happy with the speakers but found the bass to be a bit lite for some of the rock music I listen to.
I worked closely with the speaker builder tossing some ideas around.
I had him build a second pair of speakers - passive subs using the same 8 inch Usher woofer. The crossover has a very tapered slope and three cross over points. On the back side of the speaker I have three positive taps, one for each cross over point. I drive these speakers from the second set of preamp outs then through an Emotiva control freak (attenuator)- then to a separate Emotiva XPA-200 amplifer.
I love this set up since it provides close to the flexibility of a subwoofer set up but without synergy concerns. Main speakers run full range through a separate amp.
The passive sub cross over's slope is so gentle it ends up filling out the entire bass region, not just the lowest octave. When dialed in correctly the blend is seamless. So much better than any subwoofer set up I've used. The whole set up was cheaper versus the pricey Velodyne I purchased previous to this set up. Gives me flexibility for different source material too.
