My Slim Rig: 2x10 eminence Kappa Lite 3010 LF for bottom and 2X10 Eminence Kappa Lite 3010 HF for Treble. I had these cabinets made for me over 15 yrs ago but I didn't like the sound until I put the Kappas in and added 2 portal per cabinet which really opened up the cabinets sound!! The Cabinets are extremely light in weight but they rival my Bag End 2x10's!!!!  

I've got the same tuner.  I LOVE it.  I got the extender as to have the stereo signal pass through as well.  Nice rig.

About 4 weeks ago I got my Stroborack fixed and the extender added too..I'm still trying to figure out all of the ways to hook it up though, but for now I just use the 2 outputs from the rear and go into my 2 F-1 X'S.By the way I love the Stroborack too!
