Hi folks. I don't post here much. But, I do read a lot.
Going to ask for some quick opinions on a silly plan of mine for an open-baffle project for my desk at work (I own a small CNC machine-shop).
I spend a considerable amount of time at said desk programming. Right now I have a pair of Celestion 5's on my desk, and I power them with an ADCOM car-audio amplifier (you will notice a theme here, LOL).
Nothing wrong with the Celestions. They sound pretty good actually. But, I want something different.
I have a bunch of stuff laying around. And could actually whip up something really cool and industrial looking, that would fit the machine-shop vibe much better than the Celestions.
And potentially be a novel conversation piece.
And, I have always wanted to play around with an open-baffle speaker anyways.
So, what I have is a complete Pioneer PRS 3-way set consisting of the TS-C720 6.75" component set, and the add-on TS-S101 4" mid-range speakers.
Being car-audio drivers, they are obviously designed to be used in "free-air". Pioneer spects the Qts @ 7.1 for the 6.75" and 7.0 for the 4".
I have a couple pieces of cast and ground 1/2" thick aluminum tooling-plate I could machine the baffles from. The plates measure 10" wide, and 27" long (tall).
I have done a little reading on the subject. But, honestly, a lot of it goes right over my head.
What I am wondering: is this even remotely worth trying? Or is it so fundamentally wrong, the results will be atrocious?
I am not looking for the greatest speakers ever made.
I just want something that sounds pretty good at low to moderate listening levels.
And is not very fatiguing to listen to for extended periods of time.
The initial plan would be to use the passive crossovers that come with the 6.75" set between the 4" and tweeter. And cross the 6.75"s to the 4"s actively.
Amplifier will be an ADCOM GFA-4304 (30watts x 4 channels). Active crossover would be an ADCOM GFI-4600 line-driver/crossover.
I like different, and this rig would definitely be different!
Does anybody see any obvious reason NOT to fire up the mill, and waste $100 worth of tooling-plate on this project?

An externally hosted image should be here but it was not working when we last tested it.

Oh, man, just go for it! I like your idea a lot and I suspect that the 1/2" thick aluminum should make a pretty decent baffle.
In 2005 I built some Orion-style dipoles with SEAS Excel tweeters and mids and TC Sounds 12" car audio woofers. The SEAS drivers are mounted in solid Corian baffles 3/4" thick that sit atop birch-ply H-frames that the woofers are mounted push/pull in (wired out of phase).
These speakers sound so good to me that I stopped building speakers after that!
I am now revisiting DIY Audio since I decided to build some subwoofers to "complete" my system.
Was about to post a question in this section about acoustic foam when I ran across your question.
FWIW, I really love the sound of dipole/open baffle speakers and I encourage you to give some a try. With the right bits of equalization you might be pleasantly surprised.
Regards, Jeff
