Back to Speakers... Again! (Dirt Cheap Open Baffle Speaker Project)
Marvey:
Donald North (for those who do not know, he's made some awesome DNA speakers) advised me that I needed to make some open baffle speakers; and that once I did, I would never go back to box speakers. He was right.
More later...
* BTW, I'm hauling this project up to the Bay Area Meet. There will be a dedicated speaker room set away from the headphone rooms.
* Yes, those are the 8" Moth Cicada drivers up top. Those drivers, based on their TS parameters, were practically designed for OB.
* Based on the sound quality, my wife approves of the mess - most of which scattered around the house and not seen in the photo.
Maxvla:
Those look fun. Also they look easier to make. I might think about trying a pair if we can get specs/plans.
Marvey:
That's the idea. To eventually come up an easy plan(s).
They are supremely easy to make. I probably made things much more difficult by first building a frame and then detachable pieces so I could experiment. Just cutting a 4x8 sheet in half would get you almost right there.
I'm integrating the woofers right now. They are the Eminence Betas. The extremely high Qts of the Alphas scared me away. A suitable replacement for the 8" wide band driver could be found with Fostex. An alternative would be a separate 8" mid + tweeter.
So far I've only heard the Cicada drivers augmented by the subs. Surprisingly / scary good. OB speakers are like the equivalent of open headphones. All box speakers sound like closed headphones. That's a pretty big difference. I was also surprised at the speed and resolution of the Moth driver. My wife said this was the best sounding speaker I've ever made, and I hadn't integrated the woofers yet. There's a slight recess in the mid-bass with only the Moth drivers.
This is probably the easiest speaker I've ever made too. The OB woofers will be run through the cheapy Behringer DCX2496 for X-over and EQ below ~200Hz. The Moth driver will use only one capacitor in the signal path for high pass x-over.

Couldn't help it.
MuppetFace:
LOL @ Kirosia
Don't take any of the nice looking food from Purrin's table, or his speakers will wake up and eat you.
But yeah... speakers are awesome. I'm getting into speakers this year, myself.
