620B Custom

A speaker system that greatly improves on the established 620B monitor system.

The unit is a custom version of 38 cm coaxial type unit 604-8H.
In the 604 / 8 Hcustom, the manta ray Lehorn is deadened to increase the clarity of the sound in the high range.

The idea of a phase-coherent system has been introduced into the network to make the connection between low and high frequencies smoother.

Improvements have also been made to the enclosure and careful tuning of the side of the bass reflex port has been attempted.
