John Warren Posted February 14, 2002 Share Posted February 14, 2002 djk- questions about CLS M200. what is approx. price new. what are the recommended horns for Klipschorn. thanks, jw Quote Link to comment Share on other sites More sharing options...
djk Posted February 15, 2002 Share Posted February 15, 2002 The price sheet I have is about three years out of date, it has them at MSRP $275 each.I modified a K400 to use a JBL 2328 throat adaptor, that way they fit in the stock furniture.The CLS SH494 is nice, but the mouth is tall(24 X 17).They sound good on the old CLS BRH90 (think Altec 311-90) or the JBL 2350.A friend even tried them on a pair of JBL 2397.

John Warren Posted February 15, 2002 Author Share Posted February 15, 2002 a direct swap-out for the K55x-type?? no other tweak? Quote Link to comment Share on other sites More sharing options...
djk Posted February 16, 2002 Share Posted February 16, 2002 Actually, it is a fair amount of fooling around. Cut off the K400 with a die grinder where the height is 1-3/8", make a flange with a 1-3/8" X 4" opening and fiberglass onto the horn. Rough up the 2328 adaptor and add about 1/8" bondo to the 4-1/8" exit, contour to match the 4" entry on the K400. Paint up real nice. The CLS M200 is the same dB/Volt as the K55V, but it is lower impedance. I think the K55 is too loud anyway. If you add a 5R resistor in series with the M200 and a 2µF cap in parallel with the 13µF cap in the AA network, it all comes together pretty well. The tweeter crossover must be changed to a 3.9Khz Butterworth, 3.3µF + .25mH + 10µF and add a 33R 2W resistor in parallel with the tweeter. Across the M200 I wire a trap of 6.8µF + 88µH in series with half of an L-pad, terminals 2&3. I adjust the L-pad while listening to noise and then replace with a fixed resistor. This kills the 6.5Khz peak in the M200. Kind of a reverse P trap. The 5R resistor and the autoformer keep the impedance from going too low. This may seem like a lot of work, but several friends have thought it worth the effort. Quote Link to comment Share on other sites More sharing options...

djk Posted February 21, 2002 Share Posted February 21, 2002 There is no 'glare' or 'frying bacon' in the midrange anymore.Will play absolutely stupid volume levels without strain. Quote Link to comment Share on other sites More sharing options...
John Warren Posted February 22, 2002 Author Share Posted February 22, 2002 Took some effort to find a distributor. This will certainly be an interesting mod. Thanks again. Quote Link to comment Share on other sites More sharing options...
