Open Baffle Epiphany!

Pure Audio Projects

I really like this modular approach to open baffles which provides incredible flexibility to try various combinations and for future upgrades. The company will mix and match baffle flat packs for an array of drivers such as the Tang Band W8-1808s and Eminence Alphas. To enhance WAF one could easily cover the rear with speaker cloth.

Very cool
That can easily be replicated.
 
I love those but they are really expensive. I have to say I was surprised by the price. They do look like they could be replicated. It would be nice to have a set of plans.

You could take that picture and with little effort a decent cabinet maker could build a copy.
 
All I see are some steel brackets, veneered plywood and shiny hardware.

Hmmm...raiding the candy powder stock down at the shop could yield some interesting results.....

Yeah powder coating would be the way to go on that frame work. Cheaper than an automotive finish too I would think. The expensive part would be the framework. The design looks simple but when you see it broken down it pretty complicated with a lot of parts.

Yes, less expensive and more durable with an incredible selection of finishes (ok, better stop or I'll have to buy an ad banner).

Actually, that's exactly what I've been planning to do with my mockups...a modular design that uses vertical struts secured to a base to which different baffle panels can be swapped in out and in a variety of configurations. I'll just use wood (2x4's) for my vertical struts in the mockup with some gussets at the bottom.

What they have going on there in the pic would not be difficult to replicate...even if using all metal. Some rectangular/square stock aluminum for the vertical struts and flat stock for the horizontal brackets with 45 degree breaks on the ends. Drill some holes and weld some nuts to the rectangular stock on the side opposite the mounting side for your bolts to thread into and it's a done deal. I'd be tempted to use the center rear strut for driver magnet support, though. Wood could easily be substituted for the vertical supports if resonance wasn't an issue...but I think a 2x4 would be pretty inert in that regard, especially if in a rigid structure.

LOL...Actually not that much, I like simplistic and modern, but when you have a wife that consults every house decor detail with an interior designer, including my DIY projects, you learn to navigate those waters.

I have a powder coating and electroplating shop 4-5 minutes from my house...Great Idea!!!
 
Question: By using a coaxial tweeter with a cutoff around 3kHz, am I missing out on some of the "epiphany" of the Open Baffle? Should I think about a rear mounted tweeter to complement the high end? An OB/DP/BP?
 
One of my good friends has his own powder coating booth, sandblaster, etc. I could get him to do a reasonable facsimile for very little, I'm sure. He does some great work.

Not from my perspective.
 
yes, "from my perspective" ;-)

...my perspective on OBs is seemingly somewhat different than the prevailing sentiment lately... but no one else responded to you so I figured I'd at least chip in my two cents.

I don't think you'll be missing out....since all of your mid range content is still being propagated to the rear. Paul has done some designs with and without a rear firing tweeter and IIRC he preferred no rear firing tweeter with some designs. The Hawthorne designs that use the coaxial Iris or waveguide don't propagate any HF information to the rear. I think the meat of the OB experience is hearing all the mid-bass and mid range information propagated to the rear and whether or not having HF information propagated to the rear is beneficial is determined on a case by case basis.
