PO5S
The PO5S is a "perfect point source", designed to perform flawlessly across every speaker position in a home theater — from LCR to surrounds and height channels.
It features a 50-watt RMS AMT70 tweeter, seamlessly integrated with a specially developed horn, and coaxially aligned with a custom-designed 12-inch high-efficiency mid-bass driver. This precision-engineered configuration delivers top-tier sound quality, and an expansive dynamic range.
The AMT + Horn + Coaxial structure is a unique innovation by Starke Sound, ensuring coherent wavefronts and accurate time alignment. As a result, the PO5S performs exceptionally well across a wide range of listening environments and distances — from 10 to 30 feet.
Ideal for large multichannel cinema systems and high-resolution, high-dynamics stereo playback, the PO5S sets a new benchmark in performance and versatility.
