geoff.

200 ohm, 25 watt I think it says in the schematic on the second page of this thread. You should take a screen shot of that schematic, or otherwise save it, as things seem to randomly disappear on here, lol.

Does anybody know where you can get them now? I believe I read in another post this week that the supplier, has stopped supplying.

...why do I think you can get these for $200? Anyway, yes they look like KG 5.5 speakers. And they would pound the grilles off your Quartets, but they would lack the midrange detail. I always wanted to try a pair, wound up giving CF-3s a run for a while. Similar, 2-way with dual 10” woofers. If the price is right and you have room, what’s to lose? You only regret the ones you don’t try, lol.

Ummm..., does your crystal ball have tonight’s lottery numbers in it?

...I sense a bidding war, lol

I can’t find the thread, as usual, but I BELIEVE (here-say) it said the polyswitches measure .5 ohms “untripped” and immediately go to 1.5 ohms after their first “save”. They continue to work and save your tweeters, but the resistance slowly climbs each time. So your tweeter sensitivity is slightly decreased over time, maybe not even enough to notice? When they outright fail (burn out, or blow), the parallel resistor saves your tweeter, same as when they “trip”. But now you would need to open up your speakers and replace the polyswitch in order to have functional tweeters again.

Once again, this brings up the subject of a “suitable” replacement for the K-48. I know, accept no substitutes, lol. I have loved the Kappa 15C in everything it’s been tried in from Cornwall’s to La Scalas. Tight and articulate bass. From what I have on a spec sheet, the voice coil of the K-48 is 1.25mH, would it be prudent to change the inductor in the woofer circuit to 2.5mH (from 4mH) if using a Kappa 15C with an “Le” of .88mH, or a Crites woofer with an Le of 1mH?

...this is one of my KP-3.0B crossovers with the fried Klip polyswitch, if I didn’t shrink the resolution too much you may be able to see the scorch marks on it.

Yes, but I can’t see the “little yellow flat capacitor looking thing”, the polyswitch and the second ceramic resistor it is paralled with. It sits beside the red coiled inductor on the right side of the picture of the KP 3.0B. Only reason I seem to be so knowledgeable about this is that I asked a question on here about my very same crossovers a few months back, lol. My polyswitches were visibly smoked, in need of replacing. Some said for home use it would be ok to just remove the circuit, others said to just buy the 70 cent part and replace it. I bought 10, just to keep my feathers numbered in case of emergency. But in the past week or so I have read that they are really a “one time deal” as their inline impedance pretty much triples after the FIRST time they save your tweeters. They will continue to save your tweeters until you fry them, as mine were. I have replaced ANY tweeter of consequence in my preferred Klipsch with either DE-120s or DE-10s on a Dave A. horn (LMAHL or SMAHL) and have one Crites CT-120 in rotation. So I MAY go back into my crossovers and clip my Klip circuits as these drivers take more power.

...keep the Quartets until you can land some Klipsch with a 15” woofer, especially the Pro stuff. And at some point in your life, you owe it to yourself, and everyone you love, to audition a pair of La Scalas in your own space. If the price is right, they are rent free when you sell them.

It looks like someone clipped your Klip circuits!

...I was so poor I had to do the Hafler circuit with only one speaker, a Minimus 7. To the OP, if the price is right try them all and sell off what you don’t like. As another member here put it, they are free rent at the right price. Forte 2 is a game changer if you have never heard them. Quartets are impressive for their size. But Heresys are unique too. You need to hear them all in your own space. And then buy something bigger when the opportunity presents itself, lol.

...I don’t know about the titanium midrange, or the K-792 tweeter in the 301s with the 3.0B crossover All four of my KP-301s had the K-57-K midrange and K-79 tweeters(blown, lol) and 3.0B crossover. One of the 301s was a mismatch with the 4 clips holding the woofer, which was the K-48-E, WITHOUT the PWK dustcap, vented motor, and 5-way binding posts(I can only think of 3 ways...). The other three KP-301s had the wicked woofer version, the K-48-K. The matching pair has no handles, the mismatched pair does? Klipsch is always a mixed bag over the years of production. What I would like to get straight though, is a confirmation of the crossover points for the 3.0B. Does the 3.0B in fact cross at 800 and 6000hz?

You may want to “carefully” remove the passive on the back first and see if they left a wire contacting the woofer when they were “playing around” with the components. I have done this... and I say carefully because I have also created more grief by being in a hurry, sigh. If the simple fix doesn’t do it we can go form there. Cheers!

@Dave A...I owe you a soda

...help me out here, wouldn’t the crossover from a 4 ohm woofer be significantly higher to the squawker using the E network designed for an 8 ohm woofer?

What mid horn is he using here? Doesn't look to be a Trachorn.

bump for posterity

@gsgleason, a pair was just listed on Ebay, again.

...K-601 resin midrange horns I had a pair of these Cornwalls and a pair of Cornwall 2s in the same room at the same time. The fellow I bought them from suggested we do a head to head when he delivered them. Despite the different crossovers and flush vs. behind the motorboard mounted drivers we were both extremely hard pressed to hear a difference, at all volumes. The engineers at Klipsch voiced the two incredibly well, it’s almost as if they knew what they were doing, lol.

@Surtock, short answer, yes that price is high. UNLESS, that is exactly what you were looking for. Prices are high everywhere though, but your best bet is never CAM. Kijiji is your friend, but you have to be quick because all the re-sellers on CAM snap up the deals on Kijiji.

...I have seen this ad, are you in Alberta?

I can’t find a google image of a CS3? Do you have a picture of it, or the label?

Nice
