How To Repair An Rejuvenate Worn-out Subwoofer Surrounds

Introduction

I realized — a little too belatedly — that a couple of retaining clips were rubbing confronting the top of the subwoofer/enclosure in my machine. Ane clip was (thankfully) scratching the subwoofer enclosure carpet, simply the other ane had poked a pigsty on the subwoofer's rubber surroundings.

I removed the retaining clips so there would be no problems in the hereafter, just the damage had already been washed. So I figured what the heck — might as well make a guide!

Assess the damage. Depending on the severity of the cut, you may need some other scaffolding material (aside from RTV silicone) to enclose the hole.

This is especially true if a clamper of the prophylactic material is completely missing from the rubber surroundings.
In this case, all nosotros demand to do is encompass upwards the tear with RTV silicone in club to make the subwoofer almost as good every bit new — functionally, at to the lowest degree.

Unscrew the eight #2 Phillips screws using either a screwdriver or cordless driver.

Be conscientious if you lot use a cordless commuter for either screwing or unscrewing — you don't desire to strip the screws or the enclosure's holes. You also don't desire to accidentally create another hole in the rubber environs with either tool.

Employ a flat pry tool (such as a flat-blade screwdriver) to prop up an border of the subwoofer.
In my case, I merely used the Phillips #2 screwdriver I had on-hand.
Slide your fingers underneath the sub so that you go a good grip on its edge.
Carefully lift the subwoofer out of the enclosure, minding whatsoever wires that may be tethering the sub to the enclosure.

Apply a clean, lint-free cloth to wipe away whatsoever clay/grease/grime that would otherwise tarnish the bail betwixt the rubber and RTV silicone.
Inspect the underside of the tear and also gently clean information technology with a cloth, if needed.

Time to become dirty. Put on your favorite make of nitrile or latex gloves.
Put a dab of RTV silicone on a dispensable plate, or some other clean, non-essential surface.

Cut the end off a cotton fiber swab in order to transform it into an RTV applicator.
Alternatively y'all can endeavor removing all of the cotton from the swab, but you lot certainly practise not desire any cotton fibers to remain on the swab.
Dip the swab into the RTV silicone, and utilise it to apply the RTV silicone to the underside of the subwoofer tear.
You lot do not demand a huge corporeality of RTV silicone on either side of the safe surround — just enough to form a very thin layer.

With the underside coated, put a dab of RTV silicone onto your gloved finger.
Gently spread the RTV silicone across the front of the torn subwoofer surroundings.
Once again, you lot don't demand gobs of RTV silicone in order to make a potent bond — just enough to form a thin layer.

Perform this action at your own risk -- you may inadvertently open upward the hole again, depending on its size.
Push down a couple of times on the eye of the subwoofer to ensure that the RTV silicone doesn't accidentally impede the movement of the sub.

After you're done applying the RTV silicone and testing the subwoofer's excursion, smoothen a strong flashlight through the at present-covered hole, and ensure that no light bleeds through.
Ensure the sub wires are withal continued properly, and reinstall the subwoofer back into the enclosure.
