HK Audio ELEMENTS E 115 Sub D

HK Audio E 115 Sub D dual-amplifier architecture and system integration

Dual Amplifiers Power Complete Systems From One Sub

The E 115 Sub D houses two separate Class-D amplifiers: 1500W dedicated to the 15-inch woofer, and 900W available for driving up to three E 835 column speakers via E-Connect and Speakon outputs. This system-subwoofer approach eliminates the external amplification typically required for powered tops, reducing rack space, cable count, and power draw. The bass amp pushes the 15-inch driver to 128dB peak SPL with frequency response extending to 44Hz at -10dB—deep enough for electronic music, kick drums, and bass guitar fundamentals. The 900W column amp divides power across connected E 835 units, with DSP presets automatically optimizing crossover points, EQ, and limiting for one, two, or three tops. This means you're building complete PA systems with a single power cable to the sub and a single audio feed from your mixer. 

 E 115 Sub D plug-and-play cardioid output and directional bass control

Plug-And-Play Cardioid Output Simplifies Directional Arrays

The dedicated cardioid output automatically generates the phase-delayed signal needed for rear-firing subwoofers in cardioid configurations—no external processors or complex cable routing required. Connect a second E 115 Sub D (or LINEAR SUB 1500 A) to the cardioid output, position it rear-facing behind the main sub, and you've created a directional bass pattern that focuses energy forward while canceling output behind the system. This dramatically reduces stage wash in live performance environments and minimizes low-frequency buildup in reflective rooms. The plug-and-play functionality means you're not calculating delay times or worrying about polarity—the sub handles the signal processing internally. Combined with the four presets optimized for different E 835 configurations, you can deploy complex cardioid arrays with multiple tops using nothing more than the front-panel controls or remote DSP software over the network.

 HK Audio E 115 Sub D networked DSP control and LINEAR 7 compatibility

Networked DSP Control With LINEAR Series Integration

Ethercon RJ45 connectivity (in/thru) enables remote control via HK Audio's DSP CONTROL software for Windows and Mac. The onboard DSP runs at 96kHz sample rate with less than 2.6ms latency, providing 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. This level of control is essential when integrating subs into existing systems or correcting for room acoustics. Full compatibility with the LINEAR 7 series means you can network E 115 subs alongside LINEAR 7 speakers and control the entire system from a single software interface—useful in fixed installations where multiple zones or speaker types need coordinated management. The compact 19" x 19" x 23.4" MDF cabinet with water-based black finish weighs just 65 pounds, and dual MultiGrip handles support balanced single-person lifting. The modest footprint and weight mean even large cardioid setups with multiple subs and columns fit in standard vehicles without requiring cargo vans or trailers.

Highlights

  • Dual Class-D amplifiers: 1500W for bass driver, 900W for powering up to three E 835 columns
  • 15-inch woofer achieves 128dB peak SPL with 44Hz (-10dB) low-frequency extension
  • Plug-and-play cardioid output automatically generates phase-delayed signal for directional arrays
  • Network-controllable DSP (96kHz, <2.6ms latency) with 10-band parametric EQ and comprehensive processing
  • Four presets optimized for 1x, 2x, or 3x E 835 columns plus remote control mode
  • Full compatibility with HK Audio LINEAR 7 series for networked multi-zone systems
  • Compact 65-pound design with 19" x 19" footprint for single-person transport and setup

  • 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.
