HK Audio Premium PRO 210 SUB D2

HK Audio PR:O 210 SUB D2 dual 10-inch woofer configuration

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. 

 PR:O 210 SUB D2 adjustable crossover and stereo preamp outputs

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.

 HK Audio 210 SUB D2 compact dimensions and portable design

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.

Highlights

  • Dual 10-inch woofers with 2-inch voice coils deliver 126dB peak SPL with 40Hz (-10dB) extension
  • 600W peak Class-D amplification with active protection circuits (subsonic filter, peak limiter)
  • Adjustable active crossover (75Hz to 150Hz) with dedicated L/R mid/high outputs
  • Stereo preamp maintains separate left/right channels for true stereo system configurations
  • Compact 60-pound design with modest 14.6" x 24.4" x 20.9" footprint
  • Dual M20 pole mounts support flexible speaker positioning and stacking options
  • Combo XLR/jack inputs plus XLR thru and mid/high outputs for versatile signal routing

  • If your item is available and ready to ship within 1–2 business days, we will process the charge and arrange for shipment.

  • If your item is on backorder or unavailable, the pre-authorization will be voided and you will be notified by email.

  • Please note: While most items ship out within 1–2 business days, total delivery time is typically 3–5 business days, depending on your location and carrier handling.

Order Shipment

If your item is in stock and your payment has been processed, your order will typically ship within 1–2 business days. Total delivery time is approximately 3–5 business days from the date of order. Once shipped, you will receive tracking information at the email address provided during checkout within 24 hours of dispatch.

The Distributor-Direct Advantage

To ensure you receive the most recent hardware revisions and 100% factory-sealed units, Pro Audio Reserve utilizes a Distributor-Direct fulfillment model. Unlike big-box retailers that may ship "floor models" or gear that has been sitting in general-purpose warehouses, your equipment is pulled directly from the primary manufacturer hub, serialized, and dispatched. This process ensures the highest level of quality control for professional-grade recording equipment.

Shipping Policy

We currently offer free shipping within the United States only. If the checkout process on our website allows you to enter a shipping address and complete your order, your location is eligible to receive delivery.

Changing Shipping Address

If you need to change your shipping address after your order has been processed or shipped, we will do our best to accommodate the request. Please note that address changes may result in delivery delays. Any additional costs incurred due to address changes, including carrier fees or rerouting charges will be the responsibility of the customer. No exceptions.

Shipping Times

All shipping times provided are estimates and should not be considered guarantees. Most orders ship out within 1–2 business days from the time payment is processed. However, total delivery time is typically 3–5 business days, depending on your location, carrier performance, and supplier fulfillment timelines.

We work closely with our vendors to ensure timely deliveries, but please note that supply chain disruptions, high-demand periods, or weather events may occasionally cause delays beyond our control.

  • To avoid misunderstandings: The “shipping time” refers to the total time from order placement to final delivery, not just when the item leaves the warehouse.

  • Cancellations: If you choose to cancel your order because it has not arrived within the estimated delivery window, you may be responsible for applicable shipping charges, restocking fees, warehouse handling costs, and other related fees.

  • Chargebacks: Customers who initiate chargebacks due to shipping delays without contacting us first may be held legally responsible for losses. We strongly encourage open communication so we can resolve any delivery concerns directly and efficiently via our Atlanta-based support team.

Delivery Options

  • Threshold Shipping: Your item will be delivered to your front door, porch, garage, or a covered entryway.
