OK, so I'm NOT crazy, but putting K-33's in some old FH-1 cabinets gives me smoother bass in MY ROOM than corner horns. I just needed to cut out that nasty 150 Hz. peak that the FH1 (LaScala bass bins have it too), via my active Xover rolloff control on the little sub amps I'm using from parts express. Very touchy tweaking of the bass, but I finally have it, along with my coffee table sub. Also, it dropped my "stack" about 14" so now it's only 5'10" tall instead of 7 plus feet!! New Avatar to follow.
For now, no MWM or Khorn bass for me, these FH1's go to 50 Hz. and my coffee table subs go from 60 Hz. down to about 15 Hz. (-6db). See the plot I made with 1/3 octave smoothing AT MY SWEET SPOT!! This is after Audyssey EQ, of course, with about 3 db more gain on the coffee table sub than recommended by Audyssey. This is still 3.5 db LESS than what I had with corner horns. This defies previous logic, but the measurments don't lie. It sounds the best ever. I'm hoping to get my LAB horns done this winter, which should give me an additional octave lower than the FH-1 bins AND an even lower profile. Synergy horns will be next after the LAB 3.0 horns....gotta keep saving space without spending too much money. Check out the plot below, as measured 12.5 feet from the stack, both channels driven. System response right to my ears is 15 Hz to 12 Khz (includes tweeter power response room rolloff, which all systems should have in rooms)+/- 4 db in a real room with only a drop ceiling and cheap paneling.......WOW.
