question about head and speaker cabinets

Post by rutledj »

Can someone enlighten me on how you normally mount the chassis in the head cabinet? Seems like a read that Funk supplies some metal strips but I can't picture where they would be used.

Secondly, what is the most common method for attaching the grill cloth to the speaker cabinet. In the past I have just mounted it to the baffle but I'm thinking there should be a better way in case you wanted to remove the speaker.

Thanks

Chassis are usually screwed to the cabinet with big machine screws, usually backed with rings or washers. They screw into each corner of the chassis which should have a nut (T-nut, pem nut or similar) to receive it. I like to mount little rails (I usually use wood) that support the chassis just a few mm below it's 'final' location so I can slide it into position and let it rest while tightening (or loosening) the screws. Also, See picture for a Dumble enclosure for another example.

For grill cloth, here's what I do: If the speaker is rear mounted (most common for me) then I install T-nuts on the front of the baffle, paint everthing black, then staple the grill cloth to the baffle. If it's a front mount, you'll want to build a separate light weight frame (also painted black) to mount the grill cloth which can then be attached to the main baffle with velcro.

I think you drill holes up through the bottom that correspond to holes in the closed side of the chassis. It probably works pretty well if the bolts hold on rubber feet.

As for the grill cloth, a removeable option would be to build a frame out of 3/4 by 1/2 inch (or somewhere in there), wrap the grill cloth around to the back and staple it, then use some velcro or something to hold it in. That's how its done in my Bassman 20.

Just some suggestions, I'm sure there's more than one way to skin that cat.

Are there any benefits to a front mounted spkr vs a rear mounted one?

The aluminum strip is decorative and goes across the front of the cabinet under the chassis.

The original question

Post by bnwitt »

I think one of the original questions was how to mount the Funk chassis into a head cabinet. Attached is a picture of the piece of hardware used by Dumble and I assume replicated by Funk on his chasis. Funk, care to share the source for this nutsert?

Also, on the baffle of a speaker cabinet, if you use Tee Nuts inserted from the grill cloth side and matching bolts from the speaker side you can easily remove the speaker later.

It's called a slab base weld nut, I think there are many sources for them.

I have to buy them about 400 min at a time, I don't know where to buy them in smaller quantity.

they are $.25 ea if you need them.
