Wow. I'm impressed with the response times on this forum.
The original system is a Klipsch Quintet (v3 I think, Purchased in Feb 2010). Unfortunately my living room layout will not accommodate Khorns as the FRONT L/R. On a side note I noticed in surround mode that the bulk of the audio come from the center channel.
I found the crossover setting per youthman's suggestion. Default was 200Hz. I set it to the lowest setting (40Hz). I was unable to locate a "large speaker" option but will keep looking.
To test I put on some dubstep via Apple TV and set the receiver to 7ch Stereo and 7ch Enhanced. Both produced a noticeable amount of bass from the Khorns. Unfortunately not a lot of the netflix content we watch is available HD surround audio. So we use the 7ch modes quite frequently.
