HK Audio LINEAR SUB 1500 A

HK Audio LINEAR SUB 1500 A 1200W amplification and 15-inch driver

1200W Peak Power In Compact Bass-Reflex Design

The 1200W peak Class-D amplifier drives the 15-inch woofer with 3-inch voice coil to 132dB peak SPL in a cabinet measuring just 19.1" on each side. This compact form factor makes transport and positioning manageable in venues where floor space is premium, yet the bass-reflex tuning delivers extension down to 45Hz at -10dB. The enclosure uses 16mm MDF construction with black acrylic enamel finish—durable enough for mobile applications while keeping weight to 65.7 pounds for single-person moves. Active protection circuits monitor voltage, temperature, current draw, and excursion to prevent driver and amplifier damage during sustained operation. The subsonic filter (24dB/octave) removes infrasonic energy that wastes amplifier power, while the peak limiter prevents clipping during transient peaks. This comprehensive protection system means you can push the subwoofer to its output limits without worrying about thermal failure or voice coil damage. 

 LINEAR SUB 1500 A variable crossover and dedicated mid/high outputs

Variable Crossover With Dedicated Mid/High Outputs

The selectable 100Hz or 120Hz crossover (24dB/octave slope) plus dedicated mid/high outputs transform the SUB 1500 A into a true system subwoofer. Feed it signal from your mixer, and it handles bass frequencies internally while sending high-passed signal to your tops via the mid/high outputs. This eliminates the need for external crossovers or DSP processors in simple PA setups. The 100Hz setting works with larger mid/high cabinets that have extended low-frequency response, while the 120Hz option suits smaller tops with limited bass capability. The steep 24dB/octave slope provides clean separation between subwoofer and tops, minimizing overlap that causes phase cancellation and muddiness. Input sensitivity is adjustable with a center-notched gain control (+4dBu at center position), allowing level matching with various source devices. The dual XLR thru outputs provide unprocessed signal pass-through for daisy-chaining additional subwoofers or feeding other system components.

 HK Audio SUB 1500 A system compatibility and compact footprint

Universal Compatibility Across HK Audio Systems

Designed as the recommended bass extension for LINEAR 3 and LINEAR 5 mid/high units, the SUB 1500 A also integrates with ELEMENTS EASY BASE, SMART BASE, and LINE BASE systems. This cross-compatibility matters when you're building or expanding PA systems—you're not locked into a single product line or forced to replace existing gear. The M20 pole mount supports stacking mid/high cabinets directly on the subwoofer for compact system footprints in installations where floor space is limited. The 19.1" x 19.1" x 23.4" dimensions fit standard vehicle cargo areas and stage corners without requiring excessive rigging or positioning gymnastics. Two MultiGrip handles support balanced lifting and positioning, making single-person setup practical for mobile DJs and small production companies. The IEC power socket with V-Lock cord retainer prevents accidental disconnection during shows, and the 100-240V universal voltage compatibility eliminates the need for external transformers when traveling internationally.

  • 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.
