My impression of my WATT/Puppy 6s was that they were a little hot in the tweeter and didn't go down to the lowest octave. My room is somewhat on the dead side so I was OK with the tweeters, especially after experimenting with toe-in.
I have two subwoofers to supplement the low end. I'm using Sunfire True Sub Signatures. I like the idea of subs because I have flexibility to locate the subs optimally for room modes, etc, while I can place the tweeters for best imaging. The Sunfires go low enough and can punch out the volume when called upon. They also seem fast enough to keep up with the Puppy's -- I haven't observed integration problems.
So far as tinkering with the 6s themselves, I haven't been unhappy enough nor brave enough to disassemble and experimant with a $20,000 pair of speakers.
