Rat Shck Presidian 40-5053. Next Sonic Impact?

Johnk,

You're talking about a simple open baffle speaker, right? For those who didn't follow John's previous post, it is simply a piece of plywood with a hole cut in it and a driver mounted in the hole. A shelf bracket is mounted along the bottom of the piece of plywood sticking out to make a simple prop to keep the plywood from falling over.

It can be a great sounding speaker, but it will not pass the WAF test. This is a "man cave speaker" only IMHO.

John, what kind of bass response are you getting with the Fostex? There are some "OB specific" drivers coming out soon, including one from Hemp Acoustics. If it is as good as the current FR8.0DIY (installed in a simple bass reflex box) it will be outstanding.

Enjoy,

TIC

i'm also interested in the specifics of this inexpensive OB project (e.g., exactly where in the baffle is the driver mounted etc.). one wonders how to make such a thing more aesthetically acceptable--maybe triangular MDF braces along the sides for support/stability and the proper angle, sanded and painted an unobtrusive chick-friendly pastel, along with some type of removable (? magnetic) grill? certainly a challenge.

Musicdoc,

I see that litekeys has posted his upgrade kit to the Presidians on ebay for $27.50. He says he may not make many of them because of the expense and labor involved so if you're interested you might want to jump on them, do a search on his user name, 'litekeys' or on 'Presidian.'

Thanks for the heads up - just bought them. I'd assume he'll post another set soon.

Now wondering if I should have waited for a litekeys upgrade2.0 - which would undoubtedly convert these into a line-array 3-way design with the addition of two more pairs of Presidians! :)
