I dislike SPL setups, not in a hater kinda way but it's more of a different strokes for different folks kinda thing. I like to hear the full spectrum of music; even though I listen to a ton of electronic I just don't like that crazy overpowering bass.

I am a SQ freak, always have been.

Also, W7's would require a complete redesign that wouldn't look as good IMO. I don't believe there was enough room for W7's; the JL dealer tried their hardest to sell them to me.
