Hey MJ,
Interesting charts....though I have to laugh a bit. At first I thought there was a bunch of good info on each speaker....... until I realized it was the same 5 specs listed in 5 different languages!......lol Clearly the Chorus IIs beat out the Fortes and Quartets in sensitivity. But, from what I see, they all seem to travel in about the same Frequency range........so doesn't appear that one has any great advantage over the other. With 100 watt capability, I'm probably OK using just about any amp I own.....as all are 'tube' units, most with only about 15 to 35 WPC. The amp I build most frequently is the revised Magnavox 8600 unit done by Dave Gillespie and with a LOT of info here on AK. I affectionately dubbed it the DG-SE1....which has kind of stuck! I've built the circuit about 2 dozen times now in various iterations. But, in any form, they're all about 4 watts / channel....so needless to say, the higher the efficiency of the speakers, the better these little amps sound. On Cornwalls you'd think you were listening to far more substantial. On Forte IIs.....still excellent. I've yet to try my Quartets on anything other than my little home-made revised Dynaco ST-35 using Shannon Park's revision circuitry.....or parts there of. I rather did my own version using Dynaco's 'stock' output section and Shannon's driver stage. Worked out well....and no 7247s to have to go buy!
I'll get a hold of Mr. Crites! He's an old friend....though I've not spoken with him in the past few years. He may not even remember me at this point. But, I'd guess after some conversation he will. And, you're right about him being the resource to go to on this kind of thing. I know of no other 'Klipsch' expert on the vintage stuff with any better knowledge the Bob.....except perhaps someone still at the factory. And, I don't know a soul there!!
By the way, I should mention that your package arrived yesterday. I've not yet opened it...... and upon doing so I may just go ahead and do all the dampening you referenced and then just put them both in my cabinets. I did 'repair' my original woofer....... used it for about 2 days without any real detrimental affect from either the damage or repair. I then found 1 'original' for sale on ebay and bought it....installed it......and in reality nothing sounded any different. In short, I think they sound great!! And, like I said, I'm only using about 15 WPC to drive them. I have a project slated for this winter, a complete re-build of a Citation 5 power amp with all the bells and whistles available. I forget the name now of the chap I purchased it all from, but it's complete power supply revisions, coupling cap replacement, meter repl, a some other odd-ball stuff. I think it even adds a choke where there was none before. When done, we'll see how that amp drives the Quartets.....as that will become my new 'living room' amp where the Quartets now reside.
Anyway........ thanks again for all your help with this. I'll let you know once I get in touch with Bob....which may not be until after the first of the year. Until then, stay warm up there in the cold country. BTW, just exactly what part of Canada are you in? I had attempted to take a motorcycle trip into Canada this past summer. I was going to enter Canada up at the Niagara Falls bridge, make a run up to Toronto, then up through Sudbury and on back into the US at Michigan's Upper Peninsula at Sault Ste Marie. Having grown up in Michigan, we used to run up to Canada all the time, particularly in my youth. I even had a girlfriend in London Ontario for a while. I don't remember them even looking at my driver's license back in those days. Anyway, now I guess it takes an actual Passport.....of which I did not have. So I ended up leaving Niagara Falls on the US side, headed through Erie, PA, up through Detroit, on up to the Mackinaw area where my younger son now own's 10 acres of property. He's built himself a tree-house up there that rivals some luxury apartments!! A frickin' tree house!!! Anyway, I finished my ride by heading down Michigan's western shore, then on back to Baltimore. About 3000 miles in 10 days. A good ride! Hopefully next summer I can do this as I'd originally planned....only the next time I'll have my passport. I was just wonder how far off my path you are? I always like to stop and meet people I've gotten to know on this and other web sites. Nice to put a face to a name......not to mention mooch a cup of coffee....(or even a beer.......lol).
OK......I'm out!! Thanks again, Tom D.
)...enjoy!
