Many ways to go about it. Always fun to experiment. The trim I had for an HIP was beat to heck so I buffed it out with a wheel and finished off with scotchbrite. Didn't go crazy, just clean up 80-85%ish. If you do polish, wear a mask as it is not good to breath in the anodized dust. My LSi splits only get used in my warehouse or outdoors, so I never touched them. Not beat up but not exactly pretty either.

Well said Neil (and others). It used to be a "community". Like minded people helping each other with our little hobby (loving our Klipsch speakers) Now its google info answers instead of real world experiences. Met many good guys here, had several to my shop. Time marches on. Just disappointed to loose what was a good place to visit. Even more disappointed that Neil didn't mention me in the OP, but hey.....

Just for giggles, I was going to try a little elbow grease on a couple K700s I have laying around (that may end up being a lamp someday). But after inspecting them, I do not think they are the same type of alloy as the K400. Much smoother, less porous (to the eye). Not sure it would be apples to apples. Maybe try a small area on the outside of the horn??!!

You are right, cast aluminum will polish up. I have seen some nice looking auto parts. My point was the horns (in my experience) will not. Not sure if it is the type of aluminum used or the process. I had a member here bring a couple k400s to my shop to run through my paint booth. They had casting ridges in the throat of the horn possibly from the mold being made in sections. We worked like the devil grinding them down and sanding etc. The metal never looked "polished" and the tight access was a pain. I also refurbished a pair of HIPs and the extruded aluminum angle polished up nicely and the cast corners did not. There are many alloys with varying degrees of Magnesium etc. That may play a role. I predominately use 6062 or 6063 which is good for extrusions which is what we buy. Normally tempered to T6 and it will polish up. By all means give it a try. I hope it works out for you.

Point was the cast alum used in the horns will not polish up to look good. You can polish your little guts out. I process hundreds of tons of aluminum every year.

Yup, I think I see a Q... Pretty sure these are Quartets. Not worth as much as Chorus or Forte. Some people like them, I have never heard them. Thanks @MicroMara I was looking at that on my phone and couldn't make anything out. I think I see it now.

I wish I could read the label, but.... Looks more like Quartets to me based on the size differential between the horn and the woofer. They had rear passives as well. Big price difference there.

Great find @DizRotus. I had not heard of them. Very nice. Break out your "old" friends and go on a road trip to Denver. Saw they were playing Red Rocks next year. My kids took me there earlier this year as a "bucket list" gift. Well worth it. The acoustics would be great for this party band. Wear your hiking shoes.

It's been a minute since I've seen that file, but will give a look when I get to work tomorrow. Yes, it would be in in CAD

Surprised those are still around. I have have a pair almost identical and they are simply wonderful. The right person will find them and wonder why they waited so long. Road trips are fun but used to be cheaper. Good luck.

Thanks Dean

The silver ones came out of a pair of Belles that I know the history on and they have the original diaphragms. The gold ones marked with the LSi in red came out of a set of splits that I have no idea of their history. Not sure if ever used professionally or for private use the entire time. That would be a guess. There appears to be some resolder so maybe it has been replaced.

hI have two pair of K77M tweeters for sale. Both pair were working when removed. One from a pair of LSi and the other from a set of Belles. (LSI pair are marked as such) $125 per pair plus shipping from 63122. The silver pair measured 6.7 ohms each The gold pair measured 6.2 and 5.8 ohms Offers by PM only. Any other discussions are welcome. Just want them to be put to use.

Depends on who is in the other chair.

Saw Barenaked Ladies @ Redrock a couple months ago. They put on a very good show.
