I ordered a pair of Wild Burro Audio Labs 'Betsy' drivers recently. My plan was to build a pair of open baffles mentioned on the website and give them to my dad.
So the drivers came in Wednesday, I went to Lowes Thursday afternoon and got a few 3/4" edge glued pine panels. Cut them to size, cut some driver holes, sanded them nicely and finished em out.
By that evening I was enjoying some tasty Pinot Noir from Oregon and some tunes through the new speakers.
They sound great, the bass response really surprised me, admittedly I wasn't expecting much there, but there is much more bass response than I thought would be there.
I am enjoying these so much. Damn fine product.

Great and nice work. You have made the design that appear in the page of Wild Burro Audio, a 'folding screen' style. Also recommended the 'QUAD ESL-57' style open baffle:
JE Labs Arkiv: Open Baffle
I also are interested in the Betsy, but I like more the 'Magneplanar' style of open baffle. Anybody have try the Betsy in this model of open baffle, please, can say your impressions?:

Open baffles can have great bass. Problem is many people make them too small, in an attempt to meet modern expectations I suppose. Fortunately you are in Texas (apparently), and big is not a problem.
Nice build, congrats.

Funny, I've been thinking about a bass solution for my main system. It's a 4-way, horn loaded system. I'm using some cloned JBL 'W' bins for bass currently, covering ~40-150hz. They sound better than the bass reflex bass bins they replaced, but ideally I'd like something better.
I've considered a SLOB perhaps, with some eq down low. Who knows, I could end up building some large bass horns, thankfully I have a large living room, and more importantly a _very_ understanding gf.
I like the Chill baffle design.
Nicely done pcgab. Here's my take on the Betsy. https://speakerprojects.wordpress.com/2015/08/22/236/

Thanks!
I had thought about pairing the Betsy with an Alpha 15 as well. I may try it still at some point.
Well, horns are folded up baffles, so the pioneers chose one or more 18" woofers on OBs to support their mid bass - lower treble horns [note the gap]:

I'm currently looking for drivers for my upcoming OB project.
Right now I have a pair of 8" GRS drivers augmented with some 1" dome tweaters in a bass reflex cab.
OB has always made me curious and I've decided to try building one. My plan is to cut a 35.5"x31.5" baffle out of 3/4" ply or hardwood.
For the drivers I'm considering some Visaton BG20, the wild burro Betsy, and possibly a Fostex.

Nice looking project.
You can get 4 GRS 15" woofers delivered to your door for $100. Put two on each baffle with a fairly big coil in series. Top that with a Wild Burro and you're good to go. Optionally add a cap in series with the Betsy to limit her excursion.
I've done this and was very happy with the results. All the bass you carve, and a sweet midrange and top end. Not Fullrange single driver of course, but still a lot of fun for not much money.

Hi tdo
You can check Monacor SP-205/8. Similar to Saba greencone, old design for open baffle.
I´ve tested it in a CheapTrick 269 and sounds really good. No deep bass (70hz -5db or so) but fast and detailed, very nice with chamber music. And cheap, 15€/each in Spain.

Might I suggest a push-pull, slot load bass section to match your horn system?
This design (ppsl) goes together really well with horns, because they also have that dynamic "slam" factor.
Sorry, I know this is OT from the post, but I just wanted to suggest this, to answer the question from pcgab.
