Deang Posted May 11, 2021 Share Posted May 11, 2021 The following information came from www.klipschcorner.com, which I think is gone now. The information on that site came from Jim Hunter and the historical archives which he maintains. In January 1968, the K-33-P (CTS Paducah KY) was adopted. In 1975, Klipsch transitioned to the K-33-B (CTS Brownsville TX) From 1975-1979, the K-33-E (Eminence), and the K-33-B (Brownsville) were used interchangeably. Here's a good way to compare (Crites woofer included). CW1526c (Crites Woofer, Cast) K-33-E/B (Klipsch Square Magnet) K-33-E (Klipsch Round Magnet) Fs = 26.3Hz Fs = 27.0Hz Fs = 34.46Hz Re = 3.36 ohms Re = 3.5 ohms Re = 3.39 ohms Vas = 506.3 Liters Vas = 343 liters Vas = 301.7 liters BL = 12.49 BL = 9.8 T*m BL = 11.93 Tm Qms = 9.93 Qms = 8.5 Qms = 7.39 Qes = 0.27 Qes = 0.68 Qes = 0.41 Qts = 0.26 Qts = 0.633 Qts = 0.388 Mms = 75.5 g Mms = 106 g Mms = 79.47 g Xmax = 7.15 mm Xmax = 6.67 mm Xmax = 8.2 mm Cms = 0.486 mm/N Cms = 0.305 mm/N Cms = 0.268 mm/N ? Sd = 890 cm² (13.5" diameter) Sd = 889.6 sq.cm I was told Klipsch stayed with the K-33-E with the higher Fs because they made a change in the back chamber to accommodate it. By the time Eminence got the round magnet version to work right with the original, lower Fs -- Klipsch no longer needed it since they had dealt with the problem on their end, and weren't interested in reverting back. 1 Quote Link to comment Share on other sites More sharing options...

bsac335 Posted May 11, 2021 Author Share Posted May 11, 2021 Deang- Just curious, do they list the parameter for the K-43? If so, could you please post it here. THe guy I bought my cornwalls from replaced the K-33's with K-43's and I'm trying to figure out the difference between the two. THanks, bob Quote Link to comment Share on other sites More sharing options...
