HK Audio LINEAR 5 MK2 112 XA


HK Audio LINEAR 5 MK2 112 XA bi-amped Class-D amplification

Bi-Amped Class-D Power With FIR Crossover

The 600W RMS (1200W peak) bi-amped design dedicates separate amplifier channels to the 12-inch woofer and 1-inch compression driver, optimizing power distribution across the frequency spectrum. The FIR (Finite Impulse Response) crossover at 1.9kHz uses a steep 72dB/octave slope to provide phase-coherent summation between drivers—critical for maintaining accurate frequency response through the crossover region where phase anomalies typically cause notches in the response. This results in smoother on-axis response and more predictable off-axis behavior compared to traditional IIR crossovers. Maximum SPL reaches 136dB peak with 128dB continuous output averaged across 70Hz to 12kHz, providing enough headroom for transient peaks in live music without compression or distortion. The 12-inch woofer features a 2.5-inch voice coil that handles thermal stress during sustained high-output operation, while the 1-inch compression driver with 1.7-inch voice coil maintains clarity in the high-frequency range. 

 LINEAR 5 MK2 112 XA rotatable horn and flexible deployment

Rotatable Horn For Adaptable Coverage

The 80° x 60° CD (Constant Directivity) horn rotates to match horizontal or vertical orientation—essential when using the cabinet as a stage monitor where you need wider horizontal coverage, or as FOH reinforcement where narrower vertical dispersion prevents ceiling reflections. The horn maintains consistent coverage across its rated angles rather than exhibiting the pattern narrowing at high frequencies common with non-CD designs. This predictable dispersion simplifies system design and reduces the acoustic treatment needed to control reflections. The 31-degree monitor angle positions the horn correctly when the cabinet is floor-wedged, directing sound toward the performer's ears rather than their knees. The DuoTilt pole mount offers 3-degree or 7-degree downward tilt options for FOH applications, allowing precise aim adjustment when mounted on subwoofers or speaker stands. Three M8 rigging points (AP-8 compatible) support flying applications in permanent installations or touring rigs requiring overhead positioning.

 HK Audio 112 XA networked DSP control and filter presets

Networked DSP Control For System Integration

EtherCON RJ45 connectivity enables remote control via DSP CONTROL software (Windows/macOS), providing access to fully parametric 10-band EQ with variable filter characteristics, high/low-pass filters, polarity control, level adjustment, delay (for time-alignment), limiting, and mute functions. The 48kHz sample rate with less than 2ms system latency maintains timing accuracy critical for live performance, while the filter presets (Flat, Monitor, Low Cut, Remote) offer optimized starting points for common applications. Flat mode provides unprocessed response for systems using external DSP, Monitor mode optimizes frequency balance for stage wedge use, and Low Cut engages high-pass filtering when pairing with subwoofers. The dedicated DSP output provides processed signal for integrating non-networked speakers into controlled systems—useful when expanding existing rigs with mixed gear. The hybrid birch multiplex/MDF cabinet construction balances acoustic performance with transport practicality, and the 38.8-pound weight makes single-person positioning manageable. Two SingleGrip handles support balanced lifting, while the black acrylic enamel finish and 2mm steel grille with acoustic foam backing protect drivers during transport and setup.

Shipping & Returns

  • We deliver all US orders in 3–5 business days
  • Free cancellations
  • Returns accepted within 30 days (unused items)

Order Confirmation

Once your order is placed, you will receive an order confirmation email. This confirms that we have received your order and have pre-authorized your credit card for the purchase. After confirming availability with our suppliers, we will proceed accordingly:

  • 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.

If you have not received tracking information within 3–5 business days of placing your order, please contact us at support@proaudioreserve.com.

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.
