JL Audio MicroSub+ Amplified Subwoofer Systems

JL Audio MicroSub+ bass solutions feature thin-wall construction with extensive internal bracing that optimizes the proprietary loaded subwoofer, and maximizes the enclosure's internal air space. In order to achieve its outstanding output and low frequency response, the MicroSub+ is offered as a Ported Enclosure. With a flared design at the entry and exit, the port wraps around two walls to produce the necessary low tuning frequency that ensures excellent low end extension and smoothness. The Microsub+ enclosure is pre-loaded with a JL Audio TW1 driver, that is specifically chosen for its astonishing bass output when in an extremely small air space.

All MicroSub enclosures are hand built in JL Audio's Florida factory using CNC-Cut High Grade MDF materials, and wrapped in top-quality automotive carpet, to ensure that the system meets the standards that we all have become accustomed to with JL Audio products. The systems arrive to you wired, loaded and ready to connect and also include a steel mesh grille to protect the subwoofer.

JL Audio MicroSub+™ Amplified Subwoofer Systems
JL Audio DCD™ Amplifier Technology

DCD Amplifier Technology

JL Audio's Direct Conversion Class-D Technology (DCD™) is purpose-engineered to be the most efficient subwoofer amplifier on the market while delivering extraordinary output with minimal current draw and heat. DCD amplifiers do away with the losses associated with a traditional "switching power supply", allowing the amplifier to achieve total power efficiencies in the 91 - 94% range. What this means to you is very little heat, ultra-compact size and enough power to fill in the low end of any modest car audio setup. Along with the specifically engineered, low-impedance TW1 driver the system extracts astonishing overall output with unprecedented efficiency.

JL Audio TW1 (Thin-Line) Driver

JL Audio TW1 (Thin-Line) Driver

The TW1 subwoofers offer an unparalleled combination of superb performance and extremely small enclosure requirements, making them an outstanding choice for the MicroSub+ systems. The driver achieves this level of shallow-depth plus performance by compressing the architecture of the TW1 using a "concentric tube" structure that supports the oversized voice coil and the suspension attachments. This permits placing the large motor structure much further forward in the speaker than with conventional designs, while maintaining excellent linear excursion capability and mechanical stability. The enclosure's slot-ported design and precise tuning of the TW1 make for the Perfect match.

The future is now

I bought this sub for my wife for a Christmas/birthday present as I was secretly upgrading her cars sound system as a whole. I was surprised at how much power this unit produces in such a small package. Gone are the days of trunk filling boxes to get hard hitting lows. If you’re even remotely thinking about getting this sub I highly recommend you do, you won’t be disappointed. The quick disconnects are a life saver for if trunk space is needed. Installation was a breeze, I cannot stress enough how awesome this thing is.
