I have started building two 3way speakers using B&C 15NDL76, 8PE21, DE250 and Eminence H290B.

The enclosures are made from 15mm birch plywood, have a volume of 85L and are tuned to 50 hz.

Did some measurements of the drivers, the crossover points will be somwere in the 600hz and 1600hz area.

Nearfield measurements show tunning at 45hz although impedance measurement shows it at 50 hz.

I also did some tests outside but the Tamp does not sound nice at all fullrange.

Yes the mid has it's own enclosure made from a 20 cm diameter water pipe. The net volume is at 4.8 liters, enough to get it down to the frequency that i need.
