HK Audio Premium PRO 2 x 10" SUB D2 Active Subwoofer

HK Audio Premium PRO 210 SUB D2

The HK Audio Premium PRO 210 SUB D2 packs dual 10-inch woofers and 600W peak amplification into a compact bass-reflex enclosure that weighs just 60 pounds. This isn't about sheer SPL—it's about delivering tight, punchy bass in applications where footprint and portability matter as much as output. The dual-woofer configuration extends usable response down to 40Hz (-10dB) while maintaining 126dB peak SPL, giving you legitimate low-frequency extension without requiring an 18-inch cabinet. The built-in stereo preamp and adjustable crossover (75Hz to 150Hz) let you create proper 2.1 systems even with active tops that lack high-pass filtering, solving the integration problem that plagues small PA setups.

In mobile DJ rigs, small venue installs, and corporate AV applications, the PR:O 210 SUB D2 delivers bass reinforcement without dominating stage real estate or requiring a crew to move it. The Class-D amplifier provides headroom for transient peaks while maintaining thermal efficiency, and active protection circuits (subsonic filter and peak limiter) prevent driver damage during sustained high-output operation. Dual M20 pole mounts support flexible system configurations—stack tops directly on the sub or use separate poles for wider stereo spacing. The two XLR mid/high outputs (L/R) plus two XLR thru outputs provide signal routing flexibility, while the combo XLR/jack inputs accept balanced signals from mixers or source devices. At 27.2kg, this subwoofer moves easily between gigs, and the modest 37 x 62 x 53cm footprint fits venues where floor space is premium. Explore our powered subwoofers for more compact bass solutions.

Dual 10-Inch Woofers In Optimized Bass-Reflex Design

The twin 10-inch drivers with 2-inch voice coils work together in a tuned bass-reflex enclosure to deliver low-frequency extension down to 40Hz at -10dB. This dual-woofer approach provides several advantages over single-driver designs: increased cone area moves more air for higher output, and the distributed motor structure maintains control during high-excursion transients. The bass-reflex tuning focuses on punch and definition rather than excessive port noise, so kick drums and bass guitar maintain articulation instead of turning into indistinct boom. Maximum SPL reaches 126dB peak at 10% THD, which is substantial output from a compact enclosure that doesn't require a forklift to position. The 600W peak Class-D amplifier provides enough headroom to reproduce dynamic content without compression, while active protection circuits prevent thermal overload and driver over-excursion. 

Integrated Crossover Solves System Integration

The adjustable active crossover (selectable between 75Hz and 150Hz) combined with dedicated L/R mid/high outputs means you can properly integrate this subwoofer with active tops that don't have their own high-pass filtering. This is critical for smaller PA systems where you're mixing driver sizes and brands—without proper crossover management, you get midrange cancellation and wasted amplifier power trying to reproduce frequencies the drivers can't handle. Set the crossover at 100Hz when pairing with 8-inch or 10-inch tops, or push it to 75Hz with larger cabinets that have extended low-frequency response. The stereo preamp maintains separate left and right channels through to the outputs, so you can run true stereo systems rather than summing to mono at the sub. The two XLR thru outputs provide signal pass-through for daisy-chaining additional subs or feeding other system components, while the combo XLR/jack inputs accept balanced signals from standard mixing consoles.

Compact Footprint Without Sacrificing Performance

At 60 pounds and measuring just 14.6" x 24.4" x 20.9", the PR:O 210 SUB D2 fits venues and transport scenarios where larger subwoofers become problematic. The MDF cabinet construction with black acrylic enamel finish survives typical gigging abuse, while the 2mm metal grille backed with acoustic foam protects the drivers without introducing audible diffraction. Two MultiGrip handles positioned for balanced lifting make single-person moves practical, and the dual M20 pole mounts provide mounting flexibility—use one mount to stack a single top, or position the sub horizontally and mount speakers on both ends for wider stereo coverage. The modest dimensions mean you can fit the sub under DJ booths, behind lecterns, or in stage corners where floor space is limited. Despite the compact size, frequency response extends from 60Hz to 150Hz within ±3dB, covering the fundamental bass range needed for most musical content and speech reinforcement applications.
