So I attended AXPONA 2019 on Friday morning. I visited with Walter in his exhibition room at the show.
CORE POWER TECHNOLOGIES A/V, EMERALD PHYSICS AND LIVING SYSTEMS AUDIO
(Room 478): So this was another treat, largely for the A’gon Forum
members. A production version of the CPT Deep Core product was
showcased, along with the CPT 1800 conditioner. The small LSA monitors
presented an impressive 35 Hz frequency response (shaking the walls)
owing to a patented, double magnet driver design that enables twice the
excursion of a typical driver.
