The idea of deliberately mis-matching subs sounds insane, but wait! I have an Onkyo TX-NR717 AV receiver, which promises 7 point TWO. Can I run the LFE output for one sub, and stereo outputs for music to the other?
What do you guys think?
Just an understanding, there is no 80% music and 20% movie based sound track as there's only the accurate reproduction of frequencies.
Mixing subs is much like running through muddy water where one can't see what's below the top of the water. It's a crap shoot. Is the puddle shallow, deep, mixed, large, small; what's under that water? When one starts mixing subs, they better know what they're doing or they'll open up a can of bad sonic mojo and make themselves sonically sick.
Based on your above, it reads as if you're wanting to use the smaller sub to enhance speaker output and the RW-12d for LFE output. If I understand you correctly, you'll need three subs; two to complement the stereo output of the mains and a more qualified sub for the LFE channel. Yes, that would work but at the same time, quite likely, mess you up due to sound wave cancellation as the mixed sound waves will interact in an orgy of interacting sound waves, bouncing around the room.
Due to this, my recommendation would be to start by purchasing and integrating "ONE" RW-12d into your music reproduction system. Learn more about the interaction of reflected sound waves (cancellation and reinforcement), the subwoofer's parametric settings, the parametric settings found in your AVR's main menu (crossover, levels, distances, bass management) and then after mastering these settings, consider buying a second or third subwoofer. Go slow. Stating the obvious, this subwoofer based hobby is a long journey, not a quick trip and hopefully you'll approach this hobby from this perspective.
As encouragement, it reads as if you're ready so buy that RW-12d tonight, get it delivered and installed in your system and go from there.....you know you want to.
