Can anyone tell me what type of thread is needed for the feet of CF4's? Mine came with no feet, just the inserts to thread feet or spikes into.

 

Thanks in advance.

The spikes on my CF-3's are 1/4-20, verified with a thread checker

 

I've also used these on some CF-2's since I bought the speakers without any spikes: https://www.parts-express.com/Dayton-Audio-DSS3-SN-Satin-Nickel-Spike-Set-4-Pcs.-240-678

I've read through all 48+ pages of this thread over the last few years but wondering if it's been asked or done.  Has anyone bypassed the passive crossovers and gone completely bi-amped using a separate electronic crossover/EQ?  I know there has to be equalization built into the passive network for the HF based on djk's comments in this thread.  (RIP)

 

I wonder if that information could/would be divulged by @Chief bonehead or maybe it could be reverse engineered.  Using an electronic crossover would prevent the amps from wasting their time/power playing ranges that aren't needed by each amp, of course.  Maybe if the LP and HP sections could be bypassed, or just rebuilt separately, it would be possible.

 

Or maybe it's not even worth it?

Yes; currently trying something like this. In my case CF-3 V2's with added JBL 2446H compression drivers on an 11x18 JBL horn (low cutoff 500hz). Haha; just love 2" outlet horns :) 

 

The CF-3's (supposedly) have a 1500hz crossover, so setting my LF at 1100hz (just a guess but it certainly should "eliminate" the CF-3's horn - and too lazy to disconnect it). HF filter is set at 550. Both have a 24dB slope.

 

So; guess you could use a 1500hz LF and HF crossover and it should work without a problem. (FYI, I am using a Xilica which is probably overkill - miniDSP 2x4 HD should be enough.)

 

Cheers, Emile

I get all of that but if I were to feel the need to change drivers out for others, I would just build a new pair of speakers and go DIY.  I'm not wanting to re-invent the wheel with the CF-3's where all that's left are cabinets, I just want to effectively bi-amp in the best, most efficient, way and keep the original drivers.   Those EQ circuits are in there for a reason and would have to be compensated for going electronic crossover/eq which may be more work than I care to get into.  

 

Mainly, I want to spend more time listening to music versus chasing rainbows and unicorns.  ;)

In case anyone is interested.  The guy who first started touting the differences in the Epic series, stating that version one is best, has recently posted on this forum.  He started the thread "Levinson and Klipsch."   Also, with a somewhat provocative posting.
