Although this was an owner-installed modification (as Peter P notes above), the mod was suggested by the Klipsch company in a page that came with Klipschorn and other "Heritage" speakers in the 70's. The impetus for this suggestion was that Klipsch had a policy of replacing blown tweeters for their customers, should one fail in service. It was usually an isolated incident back in the day. Then inexpensive high-powered solid-state power amps became widely available in the 1970's (e.g. Phase Linear 700, etc) and more home hobbyists started using their audio systems to make eardrums bleed. As a result, the EV tweeters started popping regularly and Klipsch had to change their policy. They also added the single page flyer that explained how to fuse your speakers--primarily to protect the tweeter from noise blasts (dropped tonearm, tuner noise, disconnecting sound sources without turning off the system, etc) that would potentially overwhelm the protection offered by the crossover and blow the tweeter. Many of us on the forum have copies of the document I'm describing, but my house is disorganized right now, so I'll need someone else to post it. Although they are beautiful, most members of this forum will hopefully recognize that the asking price for this pair of speakers is unlikely to be realized.

Hi SonicAngel, It doesn't really matter that the original velcro is gone, because new velcro is readily available and you can get stuff that is more robust than the original velcro. Some velcro is available that is strong enough to attach a bumper to a car, although you obviously won't want it to be that strong! Alternately, you can also use other grill attachment strategies like magnets. Please ignore the post that suggests attaching the grill with screws--perhaps the poster who wrote that was joking--because that would deface and devalue the speakers. Hopefully, you'll get some good advice from your email to Klipsch. If not, please circle back here and we'll try to help you further. Best in horns, triceratops

This is a common problem with late 70's era Klipsch Heritage speakers. The generic term for "velcro" is "hook-and-loop fasteners", and the issue is that these fasteners are sometimes more grippy than the adhesive that is holding the hook-and loop fasteners to the grille board and baffle board. If this is the problem, you'll need to separate the hook-and-loop pieces and re-attach them to their respective places with a more substantial adhesive. Is the grille board itself warped? This can happen to the thin grille board material from years of displacement, and the reattached hook-and-loop strips may not be strong enough to hold the warped board in place. In that case, you might need to work on straightening the grille board first and/or using stronger hook-and-loop fasteners. *Triceratops trivia time: "Velcro" is a registered trademark so if you write that word in a print publication without including a little "R" in a circle, you'll get spanked--but this is the internet, so no one actually cares. Owners of trademarks do this because the owner is paid royalties by products using the trademark, even though the patent for the invention has long expired. If you find all of this confusing, you're not alone. 🤡

Look closely at the photos. Nearly every cone of every driver in each of the 3 cabinets is severely dented. I know the ceramo-metallic cones are easily damaged and they are possibly still 100% functional--but even if they sound fine, they sure don't look as pretty as those cabinets! I suspect replacement drivers for this generation of the Reference Series would be very difficult to find.

The one in Portland that Hanksjim1 reposted in Alerts! has now been reduced to $2500. Maybe the seller is responding to the comments here?

The reference cited is confusing, but it says the H-700 was introduced in 1967 with a K-22 woofer, not that the K-22 woofer was introduced in 1967. The K-22 designation for 12" woofers was used long before 1967, and there were multiple suppliers over the years. As jjptkd points out, these are not H-700's because they have the smaller 1000 horn. The Klipsch engraved plexiglas badges predate pie slice badges, and the venerable vintage grill cloth matches the grills on some 1960 Klipschorns I once owned.

Shout out to jjptkd, avguytx, and woofers and tweeters! Thanks to the three of you for your thoughtful suggestions and encouragement! Since I posted my request for CF-4 grills I have been in close contact with the prior owner of these Epic CF-4 speakers. As luck would have it, yesterday the owner's wife was finally able to locate the original grills for the speakers stashed behind the door of their at-home office! I am really stoked that the grills surfaced after everyone involved thought they were gone for good. They are a bit scruffy from being stuffed between the door and the wall for a few years, but nothing that can't be put right with some new grill cloth--which will definitely be easier than fabricating new grills from scratch. Thanks to all of you for your help! What's coming next is a group listening session comparing a pair of Generation 1 Epic CF-4's with a pair of Generation 3 Epic CF-4's. That will be fun!

Found! Grills for Epic CF-4. Details on post in Garage Sale. Thanks everyone! Most owners of Klipsch Epic CF-4 speakers are probably running them without grills, and I'm hoping someone out there will agree to sell me their grills! Why? There's no way I can convince my wife that my Epic CF-4 speakers are living-room-ready without grills to cover the exposed cones, and this particular pair lost their grills long ago. I realize this may be futile. Others have tried and failed, but I've gotta try anyway! Please help a Klipsch brother out and sell me your grills! Even if the price would be impractical, I'm willing to talk about it. Thanks all, triceratops

Good point--thanks, W&T!

Thanks, wuzzzer--will do.
