K-8-K vs K-8-E

Recommended Posts

Generally this would seem cut and dry but one was in the 1985-92 KG4 and is in the current KI-102...

The previous heritage suffix changes seemed minor but these two woofers don't seem to share much in common? Could you really use the K-8-E as a replacement for the K-8-K? If not why did Klipsch choose to re-use the K-8 item tag?

I doubt it would be much of a match. The KI-102 has a freq. response of 75Hz-17kHz (+/-4dB) and uses one woofer per cabinet, while the KG 4 has a freq. response of 38Hz-20kHz (+/-3dB) and uses two woofers per cabinet.

T-S specs for the K-8-K woofer used in the KG 4:


Nomz=  4.00 Ohms   Qms= 5.900  Fs= 27.99 Hz   Cms= 1268.0000uM/N

Revc=  7.00 Ohms   Qes= 0.405  Fi=27.01 Hz    Mms= 25.5000Grams

Levc=  1.00mH      Qts= 0.379  BL=8.80 TM     Pmx= 100.0000Watts

Splo=  88.62 db    no=  0.40 %  Sb=  0.0220sqM = 34.1000sqIn

SPLi=  88.00db    ni=  0.74 %  Vas= 0.0870cuM  =3.0724cuFT

SPLi=88.58db  @  Vg= 2.00V Xmax= 4.0000mm....= 0.1575 In

These should help you locate a suitable woofer to use as a replacement.

I'm not looking for a replacement... I was just curious...?

Comparing the frequency responses of both entire systems isn't entirely fair either... the woofers could be similar but respond differently in different cabs/orientations...
