hs-25 Dual 15-inch ACM Subwoofer

Description

Think of the hs-25 as the hs-28’s “bully” little brother. Like its larger sibling, the hs-25 utilizes our revolutionary ACM technology to deliver dramatic amounts of pure, clean low end from a dual 15-inch configuration that’s no larger than most single 15-inch designs.

Patent-pending ACM (Active Compliance Management) technology, which combines both band-pass and vented alignments into a single enclosure. The hs-25 places two premium, 15-inch transducers into this configuration, with both woofers sharing a common vented chamber. One woofer’s frontal radiation is direct, while the second woofer’s frontal radiation drives the band-pass chamber.

To make the two ACM subsections combine acoustically we use sophisticated DSP to precisely align the phase arrivals of the front facing woofer, the common chamber vent and output of the bandpass chamber vent. The powerful amplifier sends 750W of pure sine wave power (1800W “burst”) with a unique optimized signal to each woofer. The
combination of 3600 watts of burst power produces over 137 dB peak output in a half space environment (ground stacked).

The unique ACM configuration requires a highly-capable transducer. The precision-engineered, dual spider, long excursion 15-inch woofer developed for the hs-25 features large, 4-inch voice coil for increased power handling and decreased power compression.

Active Compliance Management (ACM) Technology

hs-25-woofer-side-IMG_8186The combination of ACM, purpose-designed transducers, and precision electronics allows the hs-25 to deliver much higher output throughout its operating bandwidth from a remarkably small enclosure with a footprint that’s smaller than most dual 15-inch vented designs. Like all h-Class systems, the hs-25 ships with networking capabilities already onboard. There’s no need for additional cards or retrofitting. VUE uses standard IP protocols to simplify the networking process. Simply plug in and the hs-25 will automatically connect to virtually any kind of IP configuration. Users can then access and monitor network and device-level parameters through our SystemVUE software.
