Mounting speakers on Modelling Clay

I read on another forum that mounting your speakers on modelling clay improves mid bass. Have any one here tried this? And besides sound deadening, is there anything else I should do to improve sound quality?

You mean like putting the clay between the speaker mount and the metal of the car? All that's doing is sealing in case there's an air gap or to maybe stop a little rattle. I wouldn't do that with clay though, I'd use a foam gasket or silicone. Put your dynamat or equivalent and that'll do it for most applications. Unless you're making a custom enclosure or kick panel that is sealed, your stock locations are so full of holes anyways that it won't make any difference.

The point of using clay isn't entirely to provide an air seal, but to also 'decouple' the speaker from the door panel in an attempt to prevent sound vibrations from reaching the panel. It isolates the speaker to itself. It could be used as a sandwich between the baffle and the metal inner panel and then perhaps even from the baffle to the plastic outer panel but that could be rather unsightly.

Certainly doesn't hurt to try!

^ Indeed. A common problem with modelling clay is that there are different kinds and no specifications on them. Some harden, most dry out, some are oily and will shift, stain, or run over time and with heat.

I'm about to play with a product that doesn't do any of that. I'll let you all know how it goes

Harbutts plasticine, never dries out! It says so on the pack... But also, I just used some a few weeks ago from a pack that was opened a few years ago, still good as new!

I Highly recommend it. Plus, it's made in Canada.
