Woofer dust cap repair advice, HELP

Nate,

You need two things, one is a quick fix, the other is more long term, I have both.
1 - Scotch packaging tape is more adhesive than masking tape and works great. Cut a small piece and make sure your fingers do not come into contact with the adhesive. Apply the small piece of tape and just rub it gently with your finger nail. Then leave it for a couple minutes. Pull it out slowly, not directly forward, at an angle so it stays adhered for longer.....voila!
2 - Barbed wire. I have a roll in the garage, it doesn't look good but it sounds ok and works a treat with kids.

Always glad to help

The dust cap shouldn't affect the sound. Use blue tack or masking tape to do what you can.

Otherwise, there are speaker repair companies that can cut off the old caps and glue on new ones: Tri-state loudspeaker in Aliquippa Pa is the best I've seen.

Hello Nate. Yes, the smartest thing to do is call Kharma for their professional advice.

However, since you asked, I have a little story for you. Awhile back, I was in a professional music store where they sell band and recording studio equipment. I had a passing interest in a beat up pair of Yamaha NS40 studio monitors. The salesman wanted 50% off retail price and I was only willing to pay 75% off retail considering the cabinets were terribly abused and (3) of the woofer dust caps (made of white paper) were pooched in.

The salesman said the (3) pooched in dust caps were not a problem...and I said yeah, right. Sure enough, the salesman had a technician repair all (3) of them in less than (10) minutes right before my eyes.

The tech carefully hand twisted a 1/16" drill bit into each dust cap. He then straightened out a paper clip, curled the tip of the paper clip slightly with needle nosed pliers, carefully inserted the curled tip of the paper clip into each of the 1/16" predrilled holes, and in just a few short minutes the tech had the dust caps looking like new. The tech finished the job nearly to perfection with (3) small dots of Elmer's white glue.

I then had to eat my words about the pooched in dust caps. Still yet, I had to pass on the 50% off retail before the guy started refinishing the beat up cabinets.

Nate, I hope this helps. I like Elevick's idea above of gluing on new caps if my idea does not work out for you.

Regards,
Dan

Nate...I have one other possibility for your consideration. Last Christmas, I received a complete 1/2" diameter set of "Mini Attachments For All Vacuums." I have not used it yet, but it says it is adjustable for both full sized and hand held vacuums. It is made specifically for the cleaning of computers, office machines, and stereo & video equipment. It looks to me that you can get adjustable suction in very tight spaces with this clever gadget. I don't know at the moment where my sister bought it, but I'm sure you could quickly find a little set somewhere here on the internet.

Use a pin! Unless you are performing the work in full view of a customer, in which case the 1/16 drill and carefully bent paper clip will make it look like rocket science.
