JL Audio E-Sub 12-inch (300 mm) Powered Subwoofer

Exceptional Output and Audio Fidelity | Available at Trimira Audio

The JL Audio E-Sub e112 (E112-GLOSS-240V) is a high-output powered subwoofer designed to bring JL Audio's advanced driver and amplifier engineering to demanding two-channel and home-theatre systems.

Featuring a 12-inch long-throw subwoofer driver, 1500 W RMS internal amplification, a sealed high-density enclosure, and comprehensive analogue integration controls, the e112 provides substantial low-frequency output in a relatively compact cabinet.

At Trimira Audio, we recommend the e112 for listeners seeking powerful, controlled bass for music and cinema without stepping into the larger Fathom-series enclosures.

Key Features & Technological Innovations

Proprietary 12-Inch Long-Throw Driver

The e112 employs a 12-inch (300 mm) long-throw driver engineered around a substantial motor and suspension system.

JL Audio's Dynamic Motor Analysis (DMA) methodology is used in the driver design to optimise motor linearity during demanding excursion.

1500-Watt RMS Internal Amplifier

A dedicated 1500 W RMS continuous switching amplifier provides substantial power reserves for high-output operation.

The high-efficiency amplifier architecture is designed to deliver significant current to the driver while maintaining controlled operation during demanding musical and cinematic passages.

Integrated 2-Way Active Crossover

The e112 incorporates an analogue active crossover with line-level outputs, providing useful integration options for stereo systems.

The crossover can be used to manage the relationship between the subwoofer and compatible main loudspeakers or amplification components.

Comprehensive Subwoofer Controls

A top-mounted control panel provides access to key setup parameters including:

• Gain
• Low-pass filtering
• Phase
• Polarity

The controls are positioned beneath a discreet trim panel to preserve the subwoofer's clean exterior appearance.

Rigid High-Density Enclosure

The sealed cabinet uses high-grade MDF construction with internal bracing designed to reduce:

• Cabinet flex
• Structural vibration
• Unwanted resonance
• Acoustic coloration

The high-gloss black finish provides a refined appearance suitable for dedicated listening rooms and media spaces.

Technical Specifications

Two-Channel & Home-Cinema Integration

Two-Channel

The e112 is well suited to high-performance stereo systems where the objective is to extend the main loudspeakers into the lower octaves while retaining a compact system footprint.

Its line-level crossover and phase controls provide flexibility when matching the subwoofer to the main speakers.

Home Cinema

With 1500 W RMS amplification and a 12-inch long-throw driver, the e112 provides substantial output for media rooms and dedicated home cinemas.

For very large rooms or extreme cinema SPL requirements, larger Fathom or Gotham models may provide greater headroom.

Installation & System Setup

The e112's relatively compact enclosure makes it easier to position than larger flagship subwoofers.

Trimira Audio can assist with:

• Optimal subwoofer positioning
• Crossover configuration
• Phase and polarity alignment
• Stereo system integration
• Speaker-level versus line-level connection
• Home-cinema LFE integration
• Multiple-subwoofer planning
