Default My First Open Baffle (and hopefully last)

My take on the Lampizator P17 Endorphin project.

Main driver is a 10" Coral vintage alnico coax. It is crossed over at 120Hz with a first order using Solen and Blackgate F caps.

Bass augmentation is from a 18" Peavey Blackwidow. First order crossover using Solen inductor.

Unlike Fikus Electric, I gave each driver their own front baffle. This allows for a 21" wide on the bass box vs a 12" baffle on the full range. It also allows placement of the drivers to time align the drivers to the listener.

Front baffle is 1.5" walnut butcher block finished with 5 applications of Tung oil.

Bass box is 1" thick made from Russian birch ply bonded to MDF. Finished speakers very heavy. They are fitted with 3" castor wheels to lift them off the ground and allow easy placement.

I am sure these are not the 'ultimate' OB, but they sound great to me. They are very open and capture a lot of micro detail. Lots of authority with easy clean mid bass and bass. They are flat from 45. There is music playing from about 35 but pretty attenuated. So they are not shaking the room with 20Hz organ notes, but they work very well on my favorite jazz, classical, folk and opera.

Thanks to all who have posted here and got me interested in OB.
