HK Audio LINEAR 5 MKII 115 Sub A


HK Audio LINEAR 5 MKII 115 Sub A Class-D amplification and bass-reflex design

600W RMS Class-D Power With Extended Bass Response

The 600W RMS (1200W peak) Class-D amplifier drives the 15-inch woofer with 3-inch voice coil to 130dB peak SPL, providing output capability for mid-sized venue systems and touring applications. Bass-reflex tuning extends response to 40Hz at -10dB while maintaining controlled output that focuses on definition rather than excessive boom. The hybrid birch multiplex/MDF cabinet construction reduces weight to 72.5 pounds compared to solid birch designs, making single-person transport manageable while maintaining acoustic performance. The 48kHz DSP with less than 2ms latency maintains timing accuracy for live performance, and the stereo preamplifier preserves separate left/right channels for true 2.1 system configurations. Check out our PA speakers to complete your LINEAR 5 system.

 LINEAR 5 MKII 115 Sub A cardioid presets for vertical and horizontal deployment

Cardioid Presets For Vertical And Horizontal Arrays

Four integrated cardioid presets—front, 1:1 vertical, 1:1 horizontal, and remote—simplify directional bass deployment without requiring external processors or manual delay calculation. The vertical 1:1 preset configures two subs stacked vertically with one forward-firing and one rear-firing, while the horizontal 1:1 preset handles side-by-side placement. These presets automatically generate the phase-delayed signals needed for cardioid patterns that focus energy forward while canceling output behind the system. This reduces stage wash in live environments and minimizes low-frequency buildup in reflective rooms. The dedicated DSP output provides processed signal for controlling non-networked speakers with independent 10-band parametric EQ, high/low-pass filters, delay, polarity, limiting, and mute—all adjustable via DSP CONTROL software without affecting the main speaker's processing.

 HK Audio 115 Sub A networked DSP control and German manufacturing

Networked DSP Control With Sustainable Construction

EtherCON RJ45 connectivity (in/thru) enables remote control via DSP CONTROL software for Windows and macOS, providing access to fully parametric 10-band EQ with variable filter characteristics, low-pass filtering, polarity control, level adjustment, delay, limiting, and mute functions. The lockable EtherCON connectors prevent accidental network disconnection during shows, and daisy-chaining supports multi-cabinet control from a single network connection. Dual XLR combo inputs accept balanced signals, with XLR thru outputs for signal pass-through and a dedicated DSP output for system expansion. The V-Lock IEC power connector with securing system prevents accidental power disconnection, and universal 100-240V operation eliminates external transformers when touring internationally. Made in Germany using pollutant-free wood, water-based lacquer, and strict recycling practices, the 115 Sub A combines professional performance with attention to environmental impact. Two MultiGrip handles support balanced lifting, and the M20 pole mount allows stacking mid/high units for compact system footprints.

  • 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.
