Rat Shck Presidian 40-5053. Next Sonic Impact?

If that the goal might be worth a shot. If you guys want cheap and realy good sound a fostex fe126e in a 3x4ft, 3/4in T. baltic birch baffle, a 2 1/2ft -2ft baffle would also work just bass is reduced .Sounds wonderful can run on low power and is affordable and a very easy build a home center would cut the baffle, a jig saw can cut hole for driver, shelf brackets work great as baffle stands. I use 1 each on back of baffle and slightly lean back this helps with image also couples baffle to floor eliminates most standing waves because of slope and allows one to use just 1 -12in shelf bracket for stands the brakets are pre drilled and a madisound cone fits if one wants. This loudspeaker is time and phase correct has no crossover is also dipole. All for $70 and some plywood brackets etc.Bet you could build a pair in a few hours and this incs time to get ply materials etc. I use shalac for finish this drys fast mins and adds to sound quality.Build a pair you will thank me later. great for SI or tubes- small SS.

JohnK, Thanks for your thoughts. I am looking to make a small bookshlf with a 4" or 8" fullrange drivers for a room setup to mate with a SET. Do you have any plans for the project you mentioned above or any other plans? Thanks

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.
