Yes interesting article. Note he uses heavy grill cloth to deal with the problem of over excursion. I would use a pair of Rubicons actively biased with 9 volt battery's. If I built another of these baffle types I would definitely go sand filled. I never could stop my solid timber baffles from sounding colored. And also note how important having 2 drivers is to evening up the bass response. Another seemly forgotten part of the Briggs baffle. All so note this and other baffles are not SE amp friendly or most 2a3 0 feedback amp friendly anyway. They need a higher damping factor to succeed. Some of the best sound I got out of mine was was from a seiman's 2000 projector amp which was designed for single speaker open baffle. It employed an el84 SE plate to grid feedback low frequency eq with sub frequency cut via reduced transformer inductance. That little el84 amp or amps gripped my km30's and rock and rolled. With open baffle my purist approach was to my ultimate torment for too long. As briggs said he used a amp with a damping factor of 15 and still eqed the bass. I will be interesting if I can get the km30's ballanced in open back boxes. If I can get them working well I will sell the suckers and buy a pair of radian 950pbs and aria wood mid horns :)

I didn't read the article, but it seem like a built-in voltage divider - Dan_ed 04:22:47 03/14/12 (8)
