Price is a bit high but they look in good condition, I would definitely haggle. https://www.ebay.com/itm/KLIPSCH-QUARTET-Speakers-pair-/264512174447?_trksid=p2385738.m4383.l4275.c10

I third that.

I actually like how the big horn extends wider than the front panel of the K. Like a big beautiful sound mushroom! And with that wood trim around the big horn... I think I am finally looking at the 'trophy" speakers I will ultimately put together and reward myself with.

That happens to me almost every time I try to upload. You have to close your browser then re-open and start over, to get your 2mb back. You'll have to clear the auto-save on the website also, so make sure you copy your comment elsewhere.

Is there a de-coder for legend speaker serial numbers?

I think that's the prettiest K-jube I've ever seen.

At those high capacitance ratings, a couple of uf's one way or another won't be audible.

Looks like the schematic is wrong.

Changes to the values of Crossover components will make significant changes in sound. Stick to stock values.

Subwoofer placement and phase can have HUGE impact on high frequency "cleanness" and imaging. Get the rf7's in more or less their best position, then move the sub around while listening, make sure to toggle the phase switch as you move.

There are several low priced tube amps from China avaliable on eBay. Is shipping from China to Europe reasonable?

I've been toying with the idea of putting false corners directly behind the bass reflex ports of my speakers. I have KLF-10's. It just occurs to me that any bass reflex speaker with rear ports might benefit from a bit of re-routing, especially if the speakers are not placed in a corner. My speakers are about 2 feet from the back wall and away from the corner. Preliminary experiments with some cardboard seem promising. Has anyone else tried this?

"Most people talk of high-frequency rolloff in rooms when it really is a bass buildup. They sound similar." -Dr. Floyd Toole https://www.audioholics.com/room-acoustics/room-reflections-human-adaptation

This is exactly the effect I was dealing with. I was getting the upper frequency registry of the sound and a boomy low registry. Now I am getting a tight slap and thump. I was missing information and getting muddy bass. Imaging is improved, better midrange crunch, and more brassy sounding highs, more "klack" less "hiss".

The truth is: It's both. I don't know why it's so hard for everyone to understand this. There is no 2 sides to this issue, there is only one. New capacitors break in. AND, your ears adjust. If it was just your ears adjusting, then your ears would get used to a poorly sounding system, and it would eventually sound great to you, and you would have no need to upgrade. We all know that's not the case. Your ears DO adjust, but just a little. Your amazing ears can discern incredibly small changes. If not, you would eventually get used to your subwoofer being a bad spot and you'd even stop noticing that tweeter that stopped working. Capacitors will give you 80+% of their improvement upon installation. The last few percent's worth of improvement will happen when enough current has flowed through and established its best path. You guys know that capacitors charge and discharge numerous times, creating significant electric and magnetic fields strong enough to microscopically displace layers inside the capacitor and re-settle them in slightly different positions? Many have liquids in them that re-distribute themselves as charge builds and ebbs. Just read a little on how manufacturer's make them. They also break them in. Or they're supposed to. But they only break in a small percentage of the manufactured batch. If they test in spec, they assume the rest are good and they let the customer finish breaking them in. Other dynamics also exist in caps and play a part in their breaking in. The improvements will be subtle, but we've all gotten our ears used to subtle changes.

Post a photo of them, we'll tell you.

Practically neighbors, I'm in Covina. I wish I had the space for a pair of those...

I was moving my subwoofer around in my listening area trying to improve the synergy between it and the main speakers. I put it in a spot where I thought the bass sounded better, but when I sat down to listen, I felt like I had lost some coherence and imaging, and within a few minutes I started getting a headache. It occurred to me to try the phase switch on the sub... And BAM!!! Everything gelled! My sub must have been out of phase (even in its original position) and when I moved it, it started playing nicer with the room but finished going out of phase with the speakers (at least it sounds like that's what happened). The thing is, the high frequency imaging seems to have improved more than even before I started moving the sub around. It must have been already partially out of phase...? I guess it makes sense that low, out of phase waves could affect all frequencies, but the difference is significant. Am I just hearing things or can an out of phase sub notably dampen your high frequency output?

Could a pair of stand-alone tweeters compliment a 2-way pair of speakers?

Speaker cables with knobs... Why didn't I think of that?

I don't know how I missed this comment! I am becoming more and more convinced of exactly what you are saying here. I have been making upgrades to my system and the most significant ones have come from improved circuits, not "better" tubes.
