Can I use Klipsch KG-5.5 woofers to replace the woofers of the Klipsch Epic CF-3 woofers? My Epic 3 woofers are damaged and want to get it working as I can't find a place to fix them. Please let me know.  Thanks in advance.

Guess Simply Speakers may have a reconed kit or repair them themselves.


C-3  K-1030-KN 10" (25.4cm) Poly carbon graphite cones 


5.5  K-1023-K  10 inch 


Look about the same but, wish could say.

@billybob    @RichardChiefRitz   There was nothing on their site that I saw.  These woofers are pretty much unobtanium for the CF-3 and 4 unless a person just happens to luck out on e b a y or something.  I'm glad I have a spare woofer and 2 spare K-64's (or K-63?) just in case.


The CF-3 woofers are neo magnet woofers and the others are regular magnets.  Not sure how well they would work but worth a try.  That's the worst part about the CF-3 and CF-4 is there are no parts available and why I sometimes debate on buying some new speakers of some sort.  lol

Finally got REW running enough to get some info on the CF2s. 

First, the good: Spectrogram looks awesome, totally straight line above the room's Schroeder frequency (and then the bass reflex runs an 80ms delay, but 'twas ever thus.

The not-so-great: My CF2's have always seemed a bit 'midrangey' and lacking in treble.  Well, there it is on the sweep; 6dB/octave roll-off above  above  ~3.5KHz.  It really seems like that should have been taken care of in the crossover, the first high-pass breakpoint is above 10KHz.  That should trade horn efficiency for CD compensation, right?  Not sure how to fix that without going active (not really an option).  3dB boost autoformers like the CF3 & CF4?   My Marantz receiver isn't new enough to be able to log into it's Audacity instance and start messing around in there.

I don't really trust the gray Excess Phase line with my set-up, but at least the trend is straight...


Anyways, I had fun.
