How to:
Remove the grills from early EPI speakers

the "How to" index

Most of the early EPI models were made with essentially non-removeable grills.

In order to access the drivers for service or upgrades, however, the grills must be removed (and subsequently reinstalled).

They were usually made from Masonite boards, and attached with random patches of hot-melt adhesive and a number of small nails.

Luckily, the hot melt of that time wasn't that great, and will break free readily easily. The nails will also pull out reasonably easily.

The hard part is actually applying force in a way that pulls out the nails and breaks the glue free.

First, locate the irregular cutout in the grill that is over the drivers. You will note that some uncurt areas of the grill are larger than others. You want to work with one of the larger corners to minimize the risk of breaking the thinner parts.

Now drive a coarse-threaded screw about 1/4" into the grill itself, about an inch or so in from a corner, and pull very firmly on the screw with a pliers. Pull in such a way that you are planning on stopping as soon as things "give", rather than as if you were trying to throw the grill across the room.

This will get things started enough that you should be able to get behind the grill and pull the rest of the nails and glue loose.

Once the grill is off, drive any nails that stayed in the cabinet flush. Remove any nails that stayed in the grill. Carefully scrape off any chunks of hot melt, slicing carefully through any grill cloth that may be enmeshed in them.

You may need to press the Masonite where the screw was flat after taking the screw out. Gently rubbing the fabric a bit should remove any sign that a screw went through its weave.

Reattach the grills with Velcro squares near the corners, and halfway along any long edges (the Velcro is included in HUMAN upgrade kits).
