yamahaSHO Posted March 13, 2022 Share Posted March 13, 2022 Anything in the wrong hands is an invitation for disaster, even an iron. I've done this several times with a heat gun with this material, without issue. Quote Link to comment Share on other sites More sharing options...

I lay the grill down (on my tile floor), and keep the heat gun 6-8" away from the material, moving over the area quickly and equally. The distance and speed depend on the heat, starting further from the material and moving in, especially as the heat really gets to temp.

ODS123 Posted March 13, 2022 Share Posted March 13, 2022 What has Klipsch said about this issue?? I've not seen this happen on ANY other speaker. While it's good some have found a DIY fix, I'd be annoyed if I had to do this on any speaker that is less than 10-15yrs old. Quote Link to comment Share on other sites More sharing options...

You want the heat even across the whole media. You start to get a feel for it. Once you get it somewhat shrunk on the first go, stop, let it cool, and see if it's enough. If not repeat... This helps you from overdoing it. On the open areas (driver openings), take a little extra care. With my test pieces, that's where I found it could start to melt the little plastic between the gold/silver. When in doubt, move fast and keep plenty of distance. You'll eventually see what works well. Quote Link to comment Share on other sites More sharing options...
Schu Posted March 13, 2022 Share Posted March 13, 2022 that's understandable ODS123... the old Cane used to shrink, no sag... But they were lovely lovely grill covers. Quote Link to comment Share on other sites More sharing options...

I´m in the process of re-wrapping the grilles of my Heresys, just in case I have to do corrections afterwards... I have, works great, don't get too close with the heat gun and keep it moving. You can see the fabric begin to shrink and keep it moving. Get the hang of the motion along the edges, it may tighten up the center as well. 1 Quote Link to comment Share on other sites More sharing options...
yamahaSHO Posted March 14, 2022 Share Posted March 14, 2022 Man, this seems worse than I thought. This popped up on my IG. Both of those speakers look awful. Quote Link to comment Share on other sites More sharing options...
captainbeefheart Posted March 14, 2022 Share Posted March 14, 2022 I have re-clothed many vintage and modern speaker cabinets and you can use a hairdryer, an adjustable heat gun is better but so long as you keep the distance and speed even you can get the material tight as a drum. The make grille cloth to be fit this way with heat after it's stapled in place. If the cloth is not fastened tightly with either staples or adhesive then using heat will not help you. Start at a far distance and in good lighting, maybe 8" with a hairdryer. Hit a corner with heat, and watch very closely to see what happens after 2 seconds. If you don't see any difference move in slowly until you see a very slight shrink with about a 1 second time span of heat applied. I mean a very small amount of shrink, it adds up as you go across the entire grille, and you may need a few passes to get the desired tightness. Just make sure once you get the distance down keep a nice even pattern heating the cloth in passes. I have seen some companies barely even heat the material and the cloth looks loose and sloppy after time, a nice tight square pattern will emerge from the correct amount of tightening that ends up looking great and should be nice and rigid when finished. The heat also helps harden the cloth to a stronger material. 3 Quote Link to comment Share on other sites More sharing options...

I removed the grills and placed them face up on a counter. I figured out how to support the frame in more that the 6 posts on the backside, placed a thin towel over the grill and proceeded to steam iron the grill fabric into submission. It worked and has stayed flat and non-sagging for a month (longer than after I initially removed them from the box). For what its worth the iron was set to 300 degrees with steam and used some force. When you say that you supported 6 points, what exactly did you mean? I definitely want to try your method on my Heresy IV's grills, as it looks to have worked perfectly.

The 6 posts (4 for a heresy) are all that are touching the surface of the counter and if you press anywhere else on the grill, it will bend or flex. I used a legal pad with enough pages removed to match the height of the posts, thus supporting the grill. I could then iron with some downforce without the grill bending. I moved the pad around as I ironed. I also had a thin towel between the iron & the grill cloth. One of the reasons I ironed, rather than using a heat gun, was I had hunch the glue would react to both the heat and steam (plus I could regulate the heat setting on the iron). So far, so good. And yes, I have been known to iron my shirts so I know how to get wrinkles out. Quote Link to comment Share on other sites More sharing options...

SouthTexas5850 Posted October 28, 2022 Share Posted October 28, 2022 (edited) If anyone owns a spare pair of grilles for Fortes IVs they are willing to part ways with. I am in need. I am willing to put in the elbow grease if they needed repair. Thanks in advance! Edited October 28, 2022 by SouthTexas5850 Quote Link to comment Share on other sites More sharing options...
