Prismatic Sound from Joseph Audio
Jason Serinus has already reported on the excellent sound being produced by Joseph Audio’s Pearl Mk.3 speakers ($31,500/pair), which were being shown in their new, white finish and were being driven by the new Bel Canto "Black" electronics. But of more interest to this reporter were two new models from Jeff Joseph, who is shown in my photo with a pair of the Prism standmounts ($3699/pair) and a single Profile floorstander ($6999/pair).
The enclosures of both speakers are subtly profiled to give non-parallel walls (hence the Prism nomenclature) and the design goal of the Prism was to give "80% of the performance of the Pulsar" (very favorably reviewed by Michael Fremer in June 2012) at half the price. The rear-portloaded woofer uses an aluminum cone rather than the Pulsar’s magnesium cone and the tweeter is a dual-section unit from SEAS.
