Pondoro Posted November 28, 2020 Share Posted November 28, 2020 I bought two Heresy speakers, from 1983. They sound great, they have no grills. Not "damaged" grills. NO grills. I bought replacement grill cloth from Crites. I need to make the "boards" that back the grill cloth. I am a decent wood worker. I have many saws. I can buy: 1/4" plywood, in 3 or 5 layers, 1/8": plywood, 1/4" fiberboard, or 1/8" fiberboard. I have never seen original Heresy grills. 1/8" fiberboard seems to be the closest to what I have seen in other speakers. Question 1) What do you all recommend? Question 1a) What is original? Question 1b) What is considered "best"? I am sure someone will tell me to use wonder material X, to reduce some bad effect...😀 Question 2) Any chance of getting replacement logos?

Don’t know the thickness but appropriately 1/8”. You cold make a tracing out of paper of the driver openings. They are held in place with Velcro.

Sent from my iPhone using Tapatalk I can get 1/8" hardboard (Generic Masonite) nearly free ($7.98 per 4x8 sheet) at Lowes. So if I mess one or two up learning how to cut it right I'll have plenbty of backup. Edited November 28, 2020 by Pondoro Quote Link to comment Share on other sites More sharing options...

I am not sure what is "time period correct", but the grill cloth is probably not exactly right. The tops of these speakers are beat up (sides are good, the tops look like they had a lot of stuff piled on them. I am not going for "restore to original." I liked the rectangles. $15 for two.

Pondoro Posted November 28, 2020 Author Share Posted November 28, 2020 I still cannot believe no one has told me to replace the Masonite boards with beryllium or cryogenically-treated particle board. 2 Quote Link to comment Share on other sites More sharing options...

Peter P. Posted November 29, 2020 Share Posted November 29, 2020 I measured the thickness of my Heresy grills at 1/8" or just barely over. Interesting to note; the grill fabric is not just spot-glued to the frame but the entire contact surface of the cloth to the frame is glued, yet there's no visible glue. How do they do that?!

Pondoro Posted November 29, 2020 Author Share Posted November 29, 2020 29 minutes ago, RandyH000 said: it is glued on a JIG So what if I laid the board down on a piece of sacrificial plywood, outside up. Speaker holes already cut out. Paint the board with glue that will dry clear, a very thin coat. Carefully lay the cloth on the board and pin it down around the perimeter (pins go into the plywood, not the speaker board.) Let it dry. Pull the pins. Turn it over so now the outside is down. The cloth is larger than the speaker board. Fold the cloth over and staple on the back. I am leaning towards just stapling the cloth to the back, no glue. That is the conventional way shown by the YouTube gurus, and would be fairly easy to correct if you got a wrinkle or a sag. Looking for input from someone who has been there and done it.

I looked at my grills again. Stapling is not how the factory does it. Factory back edges are glued as well, with no visible glue. Damn, them factory people are talented! I would pin the fabric down to a surface nice and flat but don't stretch it, spray the glue on your grill board, masking off surfaces you don't want the glue to stick to. Lay the grill board on the fabric and go over it with a rolling pin Remove the masking tape while the glue is still wet. After the front has dried, glue the back side material.

MookieStl Posted November 29, 2020 Share Posted November 29, 2020 3M makes a great spray adhesive sold in most any hardware store. That is what I use. I do tack with a few staples but as few as possible. You may get away with just tacking and then removing the tacks. Good luck If at all possible, use some scrap to test with.

OO1 Posted November 29, 2020 Share Posted November 29, 2020 if you dont stretch it , it will sag , this Duracrest material is thick nylon -heavy -expensive, and it's cut in such a way the strands can unwind very easily -looks easy , but it aint - Quote Link to comment Share on other sites More sharing options...
MookieStl Posted November 29, 2020 Share Posted November 29, 2020 You definitely need to stretch the material. The trick is to do it evenly so the grain of the fabric is consistent. I usually tack the four corners first then work my way around. That's why I suggested a trial piece on scrap. It is not difficult, just need a little practice.
