T/S parameters for K-33

[bsac335]

Does anyone have the T/S parameters for K-33 woofer used on the Klipsch Cornwall II?

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.

Double post.

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
