I Didn’t Expect a Compact Subwoofer to Sound This Controlled: My JL Audio Dominion d110 Review
The JL Audio Dominion d110 is a compact, sealed subwoofer designed for users who want powerful, controlled low-frequency performance in both home theater and music systems. Drawing from decades of experience in high-performance car audio, JL Audio applies proven driver and amplifier technologies to its most affordable home subwoofer range.
What is the JL Audio Dominion d110?
The Dominion d110 is a 10-inch sealed subwoofer powered by a Class D amplifier rated at 750 watts peak. It sits below the Fathom and Gotham series in JL Audio’s lineup but retains many of the company’s core engineering principles, including long-throw drivers and distortion-control technologies.
Positioning in JL Audio’s Subwoofer Lineup
JL Audio’s home audio subwoofers are divided into four families:
- Gotham v2 – reference-grade flagship models
- Fathom v2 – high-end performance for dedicated theaters
- E-Sub – compact premium solutions
- Dominion – entry point into JL Audio home subwoofers
The Dominion series includes the d108 and d110. While both share the same feature set, the d110 offers higher output and deeper bass extension, reaching 25 Hz (-3 dB) compared to 29 Hz for the d108.
Design and Build Quality
The Dominion d110 uses a rigid, sealed MDF enclosure designed to minimize resonance and distortion. The cabinet is available in Black Gloss piano lacquer or Black Ash vinyl finish. Build quality is excellent, with tight panel joins, a dense enclosure, and substantial rubber feet that isolate vibrations from the floor.

The front-firing driver is protected by a rigid, removable grille that fits tightly to prevent unwanted resonances.
Driver Technology and Enclosure Design
JL Audio employs proprietary driver designs featuring very large cone excursion, reaching up to 68 mm in the d110. This allows the subwoofer to produce deep bass from a relatively compact sealed enclosure while keeping distortion under control.
The sealed design prioritizes accuracy and transient response over exaggerated output, making the d110 suitable for both cinematic and musical applications.
Amplifier, Controls, and Connectivity
Power is provided by a high-efficiency Class D amplifier with a large rear-mounted heatsink for thermal stability.
Controls include:
- Gain adjustment
- Variable low-pass crossover
- Phase control
- Crossover bypass for AV processors
Connectivity options:
- RCA line-level inputs
- High-level input via proprietary connector
- RJ45 port for optional JL Audio JLINK™ TRX wireless module
The subwoofer features automatic signal-sensing power management, placing it into standby after approximately 20 minutes of inactivity.
Performance in Home Theater
In movie playback, the Dominion d110 delivers tight, impactful bass with strong dynamic capability. Low-frequency effects are reproduced with authority, but without overhang or excessive bloom. The subwoofer does not attempt to exceed its physical limits, resulting in clean, controlled output even at higher volumes.
Music Performance
When used for music, the d110 demonstrates good bass articulation and rhythmic accuracy. Bass lines remain well defined, and percussive elements retain speed and texture. The subwoofer integrates well with full-range speakers when properly configured, avoiding the “one-note bass” effect common in many compact subs.
Setup and Integration
The Dominion d110 is straightforward to integrate into AV receiver-based systems, particularly when using the crossover bypass mode. Stereo systems without bass management may require additional setup considerations, as the subwoofer does not provide high-pass outputs for main speakers.
The optional wireless module offers added flexibility in placement, which can significantly improve in-room bass response.
Verdict: Is the JL Audio Dominion d110 Worth It?
The JL Audio Dominion d110 is a well-engineered sealed subwoofer that prioritizes control, accuracy, and reliability over exaggerated specifications. Its combination of compact size, high output capability, and clean bass reproduction makes it a strong choice for medium-sized home theaters and mixed music-and-movie systems.
For users seeking a disciplined, high-quality subwoofer from a proven brand, the Dominion d110 delivers performance that exceeds expectations at its position in JL Audio’s lineup.
