P 16 speaker project nicknamed "Endorphin"

A one-day project based on ALNICO. Budget below 1000 USD a pair.

This is a fabulouis sounding all alnico project: TRIO bass drivers - 30 cm paper alnico, Telefunken alnico 24 cm ovals, and 10 cm Saba paper tweeters.
Very minimalistic XO is sufficient.
The bass cavity has open back - no filling, no stuffing, nothing - just a frame. Therefore there is no pressure inside hence no need for strong walls etc.

The sound of this set is AWSOME.  I mean it must be heard to be believed.

This is the yellow TRIO (Kenwood/Accuphase?) alnico bass drived used in P16s
