I've wanted to put this up here for a while. Anyway, I see a bevy of dipole and OB projects around here, so it seems like a good place. I think Andy might have mentioned it here and there, but here's an "official" thread.
quick breakdown:
vented bass cab using Dayton DVC 8"
Open-back mids: Tang Band W5-704D
Tweeter: Seas 27TDFC
The XO is parallel. The woofer is 2nd order electrical, but everything else is first order electrical.
Originally, they were meant to be clones of Andy G's Blackwoods, using a linked series XO. Unfortunately, there just aren't any reasonably-priced bass drivers to pull it off in the USA. So I went for one of Dayton's great bang-for-the-buck bass drivers. This forced me to change the XO topology, and the design took on a life of its own.
Not to brag, but they did win the Budget competition at Iowa 2007, using Vifa P13 mids. As those mids became unobtanium, people asked for other possible mid drivers. Andy pointed out that the TB W5-704D would probably work well. Then, as luck would have it, a few weeks ago, Parts Express had a super $15 deal of the day on them. Now, they're back to their regular price of $23 or so... a good deal.
