The AL-3 crossover is known to be a good one.

I believe that engineer was Trey. He is active over on the FB page Klipsch Owners, run by @Paducah Home Theater, Cory. He said about 15-20 minutes is what they do in the lab. I'm paraphrasing here and if I'm wrong, please correct me. But I'm going to settle this once and for all (sarcasm!) . According to Klipsch, Inc. break-in is about 100 hours. +++ I agree with @Chris A further upstream who said "it depends." I am in this camp. I once bought some 15" pro woofers for a DIY project. I plugged them in free air to listen to them and they were just awful. Being pro woofers they were also extremely stiff. Once I got them into some boxes and played them for about a month they greatly loosened up. OTOH I've had sub drivers which sounded great right out of the box. No break-in needed. My opinion would be to play your brand new speakers normally and in about a month they will sound better. As Chris said, break-in depends on the drivers. Glad I could clear all this up! 👍 🤣

Also put electrical tape around those splices. They are not off-set by a few inches and it looks like they would easily touch the +/- resulting in the AVR going into thermal shutdown.

@Taap bassi see if this video helps.

You can do this. I've not jumped in because you've already got expert guidance from the other guys here. The secret is to go slow and not think about how complicated this is. Just do one wire pair at a time, ie Right OUT on the Yamaha to the right-side speaker, The one thing I might clarify is it looks like your speaker wire is twisted inside the sheath. That is a bit unusual, but perfectly OK. What @billybob wants you to do is to cut the plastic sheath back 2-3 inches AND THEN twist the Red wire so you can wrap it around the binding posts, and then do the same to the other wire. +++ I looked very carefully at the picture of the speaker wires. One wire is going to have a marking on it, probably a light blue stripe. Call this the RED wire. So connect RED on the AVR to the RED on the speaker. The AVR will tell you LEFT and RIGHT speakers.

For reference:

I HEAR YOU TOO!!! 🤣 I was studying your setup. Really nice! With pro speakers nearfield in a 7.1 you don't just hear the music, you are the music. Sound just comes from everywhere, and nowhere. It's like taking a sonic bath. 👍

They are in the Man Cave. They currently out of the rotation so I can test the RP-600M's with a mini-amp and 10" sub. They aren't the CF-4's but they are sounding real sweet for a near field 2.1 setup. The picture with the DIY speakers is new to me. I moved the TV and RC-64 III from the upstairs living room into the basement because my wife hates big speakers where there should be furniture. Then I kept throwing speakers at the downstairs setup until I got happy. I don't know if I'm totally happy but I'm getting there.

I used to own Khorns. I found a mod that was drop-in and upgraded the sound by a magnitude. I never liked the K-77, all those squeaks and squawks. There is no real audio content (like a trumpet) that came out of the tweeter section. I found a combination of B&C CD $106 and SEOS waveguide $28 that sounds tremendous in the Khorn. I placed the SEOS on top to time align it to the mid-range throat. I also used a Crites A/4500 XO and the B&C 250 which can easily handle the lower XO point, 4500 Hz vs the Type AA 6000.

Bundles are hard to value, at least for me.

I have the 600M and they have never popped. I agree the fridge is the likely problem. It will create a heck of a surge when the compressor cycles on.

Had: 1978 La Scala, 1979 Khorns, RC-64, and my first ever Klipsch, the RW-12d sub Have: RF-83, RC-64 III, RS-62. Want: Any deals that come along Significant Other: Currently have DIYsoundgroup: Umax 15 sub pair w/Inuke 3000dsp, Dayton Audio Reference 15 sub. Overnight Sensations, Cheap Thrill, Fusion 10 Pure. Usher MTM 7" woof dome tweeter center. MBM Mid-bass module pair, Titans 615 XL pair. Magnapan MG-1 (sold). You guys haven't seen this 5.2 Home Theater. I set it up earlier this week. That's a 65" Vizio sitting over top the RC-64 III. It looks like a toy next to all those large speakers. Lto R top to bottom: MBM 15, then the top hat for the Titan 615 LX. Bottom Umax 15 then the 15" woofer module for the Titans. Center is Marantz 6011 beside an Emotiva XPA-5. Not pictured is RS-62.

Great to score some speakers you really wanted! Enjoy.

From my 1994 CF-4 crossover. Texas Instruments, Tecate Industries made in MeXIco. Edit: Thanks for the correction, Randy

Oh, we know you didn't push her. The story you just told? No one could make that stuff up! 😄 +++ Glad the wife is mostly OK and will recover. It's now your job to carry both the dog and your wife up and down the stairs!

I track CF-4 prices. The Average is $1100 so your estimate of $1350 for a v1 is well within the range for fair market value.

If it has the grey horn that would convince me the speaker has all the trappings of a version 1. The port length and minor XO changes can be retrofit to v1 specs but not that horn. I value the v1 the highest and then deduct $100 for each subsequent version. v1=$1000, v2=900, v3=800 (round number estimates on dollar valuations)

Serial number is not correct for v1. The port length is 5.5 inches v1. Otherwise v2 Monster cable was on v1 and v2 The horn lens should be gray v1. Otherwise v2 Check the XO which is attached to the binding posts. Here's the CF-4 v3 schematic. EDIT: I just re-checked the PDF and this is the VERSION 3 schematic, no matter what the label says. The schematic specifies the RED/GREEN wires. V3 only. Klipsch CF-4 Schematic(1)(1).pdf

Glad to hear it! Those things can drive you crazy trying to find the exact problem so it can be fixed. If you are getting a buzz only at certain frequencies I would bet dollars to dough nets its the dust cap. My CF-4 had that exact problem and the dust cap appeared solid, but it was only glued properly on 3/4 of the rim. That little 1/4 looseness caused the buzzing at a specific mid-range frequency. It's hard to find, but easy to fix. The secret is after the dust cap has been glued was to get something to press down on ONLY the outside of the dust cap. I used one of my wife's round vases which had a 3" (I think) mouth. Worked great.

Don Mclean is now 70 years old and American Pie is 50 years old. Don's voice here is incredible! I love the acapella group Home Free. There are no instruments on this version, the human voice takes care of drums and other instruments.

I have album and CD. I prefer album all the way. +++ Have you ever listened to that cut on headphones? The stereo separation is so good you can shut your eyes and still SEE those two guys sitting on stools trading off guitar riffs. It's an incredible illusion.

Very pleasant guitar work, not gritty or ear piercing at all. There is also a very heavy Al Di Meola influence in there as well. 😎

For something inexpensive those floor mats which interlock can be found at Harbor Freight for about ten bucks for four. I trim them with heavy scissors. I also like shopping at Lowes because they have floor mats which are not on the web site and they're always on sale. I really like the anti-fatigue mats with the bevels like the ones for kitchen. Industrial ones are much more expensive. https://www.amazon.com/Standing-Fatigue-Kitchen-Cushioned-Stand-up/dp/B08HCKJ3GR/ref=sr_1_14?crid=2W06VELNM90E1&dchild=1&keywords=anti+fatigue+mat+kitchen&qid=1612244349&sprefix=anti+fat%2Caps%2C172&sr=8-14

Hey hey hey!!! You have insulted the resonance of my center channel and I now demand satisfaction! 🤜🤓🤛 LOL obviously, I wouldn't take offense. It's a good question/comment. You can't tell from the picture but the 8" bed risers were a short term solution to getting my TV up over top the RC-64 III. Underneath the 64 III is a 3/4" thick closed cell soft rubber mat that covers the entire width and length of the speaker. You can see it a little better from this angle of my previous RC-64 Mk1. I put everything on rubber pads. 👍 😎

Simply Speakers sells OEM Klipsch woofers and diaphragms. I didn't see the RC-64 II listed and I don't know what the part number is. Is a woofer available from Klipsch Tech support? In any case In Steven We Trust to source an OEM woofer if you want to go that route. with the II.
