Heresy IV in Cherry/Black/Walnut /Distressed White. Compact, three-way horn-loaded loudspeaker featuring significant upgrades over its predecessors, including a rear-ported design for enhanced bass, a new midrange driver and a titanium tweeter. Known for high efficiency (99 dB), the Heresy IV delivers a dynamic, "in-your-face" sound ideal for low-power amplifiers.
