    • All I did on my CF-3 v3's was extend the port length to what the v1's were, removed/re-attached the rattling back panels, did some basic interior bracing and altered the crossovers to what the v2's are, I believe, as there is no real information on the v1 crossovers.  Unless someone has a pair of CF-3 v1's and cares to reverse engineer them.   Mine sound great.  They have bested a pair of KLF-30's and '78 Cornwall's in my living room, anyway.  Results most likely would be different in a  different in a different room, but, maybe not.  The Epic series, especially CF-3 and CF-4, just sound damn good.
    • There is a good reason for that, and a reason John Eargle was able to co-create our theater sound system.  For some of us, Roy's stuff doesn't sound "like" PWK's, it sounds like PWK.  Dave
    • Mine are 1982's, consecutive serial numbers and also have the soldered dual plug version. I would keep them original. They sound great!
    • It's 20wpc.   I bought this from someone who had it stored and barely used it. Everything works with no static or any issues. I had plans to do a purely vintage second setup, but now I'm pairing down everything. It sounds fantastic and was great on my fortes (which I've also sold).
    • Justin, your attitude is totally refreshing!  You are not threatened by a competitor's limited edition product and have actually encouraged him to come out with more!  And, you don't find it necessary to bash a competitor's product as a means of trying to elevate your own status.  You are a true gentleman, and I'm sure your customers greatly appreciate dealing with someone like yourself.   Maynard
    • Steve is a handsome young man in his own right.  Anne and Nancy are extra bling.
    • Finished a couple of the filter boards.  When I was testing them I took a few pics.  The first set of tests are to drive the board off the lower rail taps and measure the heat dissipation in the power supply transistors.  I pulled the amplifier board out to avoid damaging it with an unexpected pop or blowout.  Good news was nothing happened.  The current regulating transistors on the board are MJE350/340.  No over temps, no oscillations.  The FFT plot shows the filter response of the two channels driven by the XLi power supply after about two hours of operation.  The small signals were applied directly to the input pins of the board.  This would be the response for a Klipschorn bass unit. The big caps on the board are Panasonic polyesters which is over-kill but easy enough to install.    
    • Which one and why, 19s are bringing crazy prices but I've always wanted a pair after hearing them as a teen. Putting together another system with a tube amp and TT.  Would most likely have cabs built and get drivers from GPA if I go Altec. I know this is a klipsch site so be kind:).
    • Steve only gets to post pictures of himself if Anne and Nancy are in it as well.  It's worked in the past.
    • Thanks ,my midrange speakers had the solder terminals.I was thinking of upgrading them to the K-55g ,I think I will keep what I have.
