Baenwort Posted July 14, 2023 Share Posted July 14, 2023 (edited) So I finally took my RF-7 speakers out of storage as I thought the kids had become responsible enough and my oldest (8) has become my listening buddy. However, his younger sibling was not and engaged his curiousity and maybe a little jealous too.. I'm too furious to power them up again. So I turn to your evaluation, will they work, can I fix them, or is it cosmetic and I should try to ignore it? (I need to figure out a repair for two of the grill posts that broke when the youngest pulled them off but that is a seperate project) Originals at: https://ibb.co/nrr1RY1 https://ibb.co/n6bkZrN Edited July 14, 2023 by Baenwort Fix images 1 Quote Link to comment Share on other sites More sharing options...
OO1 Posted July 14, 2023 Share Posted July 14, 2023 cosmetic damage , no worries , dust caps can be replaced Quote Link to comment Share on other sites More sharing options...
billybob Posted July 15, 2023 Share Posted July 15, 2023 Yes, welcome back! Would power them up and see. The center voice coil could be fine just dimpled like woofer, which should be good enough unless you hear a difference. If so would superglue the grille pegs. If you decide you need replacing for whatever reason, join the hunt for them. Let us know please... thanks! 1 Quote Link to comment Share on other sites More sharing options...
Baenwort Posted July 15, 2023 Author Share Posted July 15, 2023 (edited) Waiting to power it up until I'm feeling a bit less likely to fly off the handle if they have a problem. Hearing the center bit is cosmetic is calming but I wanted to add some better pictures of the three cones that have some indentations on them I'm worried about.

First look makes me think the grills are made of ABS which is easy to weld with Acetone. I'll have to test one of the broken pegs to be sure of the plastic material used. Unless someone already has and can tell me the material used? 2 Quote Link to comment Share on other sites More sharing options...

It doesn't look like there are any penetrations or holes. Would powering up cause damage if I'm wrong about any of the creases being more than that? What is a reasonable price on the used market if I have to go that way? I plan on powering them up after the kids are out of the house tomorrow on a grocery trip with their mother. 1 Quote Link to comment Share on other sites More sharing options...
OO1 Posted July 15, 2023 Share Posted July 15, 2023 powering up the speakers cant do any more damage to the woofers . new woofers cost 150$ , so used would be around 75-100$ Quote Link to comment Share on other sites More sharing options...

That explains why you were upset, you are a 3d and weld type of guy, not a “super glue and duct tape will do.” On a side note, you’re a good dad in my book. 1 Quote Link to comment Share on other sites More sharing options...

However, once the weld dries it can be wiped clean. The power up test did not find any issues with the RF-7s. Other than cosmetics. Now that the kids are back in school I plan to take a half day and fix up the speaker covers by rebuilding the pegs. Hopefully getting the issue out of sight will keep me from making things worse while trying to pop things back out. 1 Quote Link to comment Share on other sites More sharing options...
Peter P. Posted September 12, 2023 Share Posted September 12, 2023 Why not just purchase replacement pegs? Simply Speakers and Parts Express are just two places that sell them. Keep the grills on and you'll never have to look at the cones again! 1 Quote Link to comment Share on other sites More sharing options...
