Developed by SPL’s creative director of R&D, Thomas Danley, the B-DEAP design takes into consideration the physical space outside the actual box, utilizing boundaries, enclosure walls and geometry to form a bass horn external to the unit.

Traditionally, a bass horn capable of extending to 30 Hz requires an enclosure with a 10- to 12-foot wide mouth. Even a multibox segmented bass horn requires a lot of space. By employing the principal of the acoustic mirror image and the External Airpath technology, the B-DEAP system avoids the need for large-size enclosures, while delivering natural, clean, low-end sound, bypassing costly construction and transportation expenses.

The acoustic mirror-image concept dictates that when an acoustic space is halved, the mouth area of a bass horn is also halved; when corner-loaded, the mouth area is reduced to 1/8. With the B-DEAP approach, the last half of the horn is created through the existing room and enclosure boundaries. As a result, Sound Physics' B-DEAP32 is an enclosure measuring 42x42x18 inches, loaded with two 12-inch high-excursion drivers and weighing in at 175 pounds. Low-frequency cut-off is boundary-dependent (on configuration in room), typically 30 to 40 Hz.

The B-DEAP32 functions near-optimum levels when set under a stage, placed in an open space or even flown in multiples. In these applications, the frequency response measures in the mid-30Hz range at very high power.

"Our customers are looking to purchase products that reduce their system cost, increase efficiency and deliver performance beyond the norm," noted Brad Skuran, president of Sound Physics Labs/ServoDrive. "With that in mind, Tom Danley invented a new bass-horn technology that delivers low-end bass at levels users have to hear—and feel—to believe. Beta testers include Mike Hedden, president of dB Acoustics and Sound, who has already purchased over a dozen units. A decade-and-a-half ago, Danley jolted the industry with his servo motor-driven subwoofer. Today, his new bass-horn design meets all live sound criteria: price, performance and flexibility."
