I didn't knpw that the original KG2 was changed about a year after the initial introduction. The tweeter crossover freq. was lowered from 3000 hz to 1800 hz, and the impedance dropped, sensitivity went up slightly. See series two specs below.

And the KP2002c....They DO exist! Enjoy!

Here are the KP 2000c specs

1991 vintage price list
-
I think its around 1991 or 92.
-
Called the KP 650 then
-
Found the first prototype tear sheet for the KP 600
Also found some old price lists and an ad from about 1992
-
some versions had springs hanging the tweeter, i'll dig in my lit later this week
-
I think I have a brochure on this speaker, I'll try to find it if you like
Spectrum was based in Toledo.

Spectrum 208a. Look back in Stereophile, I remember them being reviewed quite favorably

Haven't heard the RF3's, but I relate to the type of sound you referred to. It took me almost 20 years to get it out of my La Scalas.
Klipsch's tend toward dry, crisp, clean 3rd-5th row sound.
For a more mid to rear hall sound it take quite a bit of modding, but I'm pleased to report it is possible.
-
The max sound pressure quote for example 121 db for the Klipschorn and La Scala is at 1 meter on axis.
Dont confuse this spec with ones averaged into a reverberant space for a pair.
It would be hard to compare the two...complex variables with room averaging...how reflective, what distances, etc.
Islander:
- It looks like the failure threshold for the Belle is 114 dB at the distance they used, with their test enviornment, with their (unspecified) two tones. I assume the tones were continuous. The 120 dB (Belle) and 121 dB (Khorn) figures we often see must be 1) Peaks? 2) Much closer up? I wish there were many more specifics stated in the report. PWK used to claim that with a Belle or La Scala as a center channel, with 2 Klipschorns as front right and left, 20 watts RMS power into each would produce a combined level of 115 dB peaks "at your ears." I have produced this with 60 wts into each (from listening position) with more probably available, but I didn't dare, because I don't have much faith in my meters.
- Sorry about the big type (12). I will reform. I often slide into my computer chair without the location of my glasses known, and the 12 type helps me read what I'm writing, then I often forget to reduce the size before pasting.

Here's the left side of the graph. It's the center spread of the catalog, not able to be scanned at once.

OOPS, I lied. Actually its 114 db w/ 4 % distortion
-
109 db at failure threshold.
KG2 series two

Here are the specs dated June 1983. Are replacement woofers available for either series?
Also noticed the power handling wemt from 65 to 100 watts, and the freq response went from 55 hz down to 35 hz.
I also see a passive radiator that wasn't on the original.
