[Magna Audio]

It all started out as a pair of conicals on top of GRF's used as bass bins.

12 compound angle petals





Glued



Used 2 pack filler to make smooth transition from 12 sides to round - the throat is the key or else they sound weird / possibly honk.

Loaded with a JBL 2435Be compression driver

As a 3 way - time aligned (crucial for really cohesive sound)
