I though I read that Mac took care of it as you would expect them to.

Yes, THANK YOU

I would wait for some more knowledgeable people to chime, I just have a very basic understanding of this stuff.

The 215 goes down to about 70hz your 904s go down to about 40hz IIRC, they won't do anything I'm afraid except muddy, create nulls, to a great engineered speaker system. If you want more low end for your 904s you need to look at 684s or an 1802. Otherwise you are going in reverse. You have a professional cinema speaker with the 904s, the 215 and 115s are for PA systems or permanent instalation,

KI-215 White (# 94315051924) The KI-215 trapezoidal array-capable (twelve built-in 3/8" 16-thread fly points) subwoofer perfectly complements Klipsch’s high power full-range loudspeaker systems. The KI-215’s enclosure dimensions and rigging configuration are identical to the KI-362 full-range professional loudspeaker system, making it an ideal match when using an external, active two-way crossover. Its highest-quality heavy-duty drive components use 104-ounce magnets and 3" voice coils as well as proprietary speaker motor assemblies to deliver high sensitivity and advanced power handling capabilities. Ideal for clubs, theaters, auditoriums, churches, and performance halls the plywood construction tuned port enclosure applies CNC fabrication techniques for uniform tolerances and build reliability.

What do you have for garage or patio. These might match up with a great sounding system out there.

That's some awesome stuff you posted there.
