Yeah my Belles have the 4 metal screws and the t-nuts.  I really appreciate everyone's input. I just finished the second speaker tonight, and there was one screw on the k33 that was almost completely screwed out. I never noticed a rattle or anything weird before, but I should've checked the original woofers and their securement when I purchased the speakers years back.   Initial impressions are exactly what everyone says. Mid bass is a little more present, and there's definitely more detail in the midrange with the eminence kappa woofers, which is great. The bass is tighter, but definitely doesn't sound as deep as the k33. I'm sure that some burn in will help out. I'm enjoying them so far. I'll keep them playing most of the day tomorrow. Eventually, I'll add my subwoofer to fill in the low end, but I want to see what they can do without it first.

Good stuff^^^   If your were just south of NY that day I recorded this, there were lots of folks on the stage! Lou, Joan, Sting at the top of my list for this tune.    

two Heresys wired in series...so that the center image was wider than pin point enter.  I experimented with clocking those two also. I thought the Heresy was awesome,but I felt ultimatelythat a single was the best solution.     Single Cornwall... sounded great for 5.1 music,but I felt the Heresy was a better center channel for Home Theater. There was something advantageous about the scale of the Heresy in relation to the two mains where the mains would get burried by a larger center speaker in HT usage.   For 5.1 music,a full size center was better.

I actually have a NIB miniDSP HD, microphone and plenty of high quality channels of amplification on hand but have decided I want all my speakers to be as plug and play friendly as possible. I've been tinkering with speakers for a long time now and have a few sets that sound pretty dam good already.    The Chief did in fact rework a set of networks for the McLaren 905's (kpt-904's) for home use but those things are pretty huge. Either way I'm happy, just think if Klipsch could throw together a 2-way, Chorus type speaker with these parts- even if it ended up being a complete break away from the Heritage line they'd be one kick-*** speaker. 

What's the blue stuff? Rice? Or a Sea Cucumber (had that once at a real Chinese restaurant with tempura soft shelled crab) Salmon looks good, never had it like that but I love it!

You are fine.

@ssh nice setup! Love the Indian, and that color reminds me of the Brandywine on the late 60s GM factory rods!

High current amp and good capacitors allow for power to get through dynamics and impedance dips. Changing the tap from 8 ohms to 4 ohms has it's trade-offs and in most cases, makes no real difference.  I have owned the RF 7, and 7II's.  I used them with SS, hybrid, pro and tube gear.  

I'd go with identical subs as well.  The lesser sub will always limit you to some extent.

Additionally, is anyone running a McIntosh or other amp off the 4 ohm taps to power rf7 s? Is that impedance dip at x over worth it sonically, and what did you notice as a difference? Does your amp need to work harder/generate more heat, and in your opinion is this worth it?
