The Absolute Sound reviews JL Audio's E-112 (1500w) active subwoofer
http://www.theabsolutesound.com/articles/jl-audio-e112-subwoofer/
"The qualities that have made previous JL Audio’s subwoofers exceptional—lack of bloat and overhang, coupled with tremendous power and authority—were evident in the new, more affordable e112. The pair of e112s was quick and agile, reproducing transient information with no smearing of leading-edge attacks, plus very fast decays. As a result, the subs didn’t dilute pace and rhythm, as many subs do."
"The JL Audio e112 seems to have sworn the Hippocratic Oath: First, do no harm. The e112 follows this dictum in two ways. First, its integral crossover is extremely clean and transparent. Second, this sub doesn’t call attention to itself by weighing down the music with a bloated rendering of the bottom end. These qualities alone would make the e112 a standout."
"It’s this combination of finesse and impact that makes the e112 such a stand-out in a crowded field—and at an eminently affordable price."

The E-Sub subwoofer driver features a radical, deep architecture designed to create a highly linear, mechanical action and a motor design with enough linear excursion to handle the challenging program material.
A totally new switching amplifier was engineered for the E-Subs, with a compact and efficient switching power supply. This design allows us to keep the E-Sub's dimensions compact while delivering ample clean power that will fully exercise the drivers' excursion ranges.
The E-Sub's feature set has been designed to allow the use of E-Subs in a wide range of applications, from full home theater systems to dedicated two-channel music systems, to desktop audio workstations. A true, two-way onboard crossover with high-pass line outputs allows the E-Sub to integrate seamlessly with two-channel systems, and high-level inputs even make it possible to add an E-Sub to systems lacking line outputs. Polarity and variable phase controls make it possible to precisely blend the E-Sub's output with that of your main speakers.
Every E-Sub is precision-built in JL Audio's U.S. factory and individually performance-verified and tested to deliver years of listening enjoyment in your home audio or home theater system.
JL Audio CR-1 Active Subwoofer Crossover -
JL Audio's CR-1 Active Subwoofer Crossover is at Musicraft (Derby)
The lucky few who have heard a well-integrated subwoofer in a great audio system know that the subwoofer's effect is profound. While everyone expects the bass extension to improve, most are shocked at the transformation that occurs in the main speakers. They simply open up, delivering improved dynamics, superior imaging and more low-level detail. Many describe it as the greatest speaker upgrade they have ever made.
Over the years, we have calibrated many subwoofer systems in highly critical listening environments, and we have been frustrated by the limitations of active crossovers we have worked with. Tired of struggling with "blunt instruments", we felt that a higher precision tool was needed, so we decided to build it and call it "CR-1". When properly set up, CR-1 creates a listening experience in which the subwoofers and main speakers become one, delivering a cohesive and compelling sonic presentation.
The CR-1 Active Subwoofer Crossover has been designed by audiophiles, for audiophiles. We believe it has no equal, offering a powerful combination of subwoofer/satellite tuning features, and a complete commitment to analogue signal purity.

CR-1 is built around two banks of precision Linkwitz-Riley low-pass and high-pass filters. Multiplying DACs with monolithic ratio matching are employed to adjust the analogue circuit's filter frequencies. This offers superior tracking behaviour and far more precise left/right channel balance, compared to conventional approaches.
Another of CR-1's unique and powerful features is a pair of rotary controls that control the damping of each filter bank. These damping controls dramatically improve the acoustic summing through the crossover region, by compensating for each speaker system's frequency response. At the center of the front panel, a single intuitive, rotary control permits quick adjustment of the relative level between the subwoofer(s) and main speakers.
To minimize distortion and noise, CR-1 employs top-grade component parts in its all-analogue audio circuitry: 1% precision resistors, JFET-input audio-grade op-amps, polypropylene film-and-foil capacitors and metallized-polypropylene film capacitors, to name just a few. We also build CR-1 right here in the U.S.A., to ensure top quality and dependability.
CR-1's input-output design makes it equally adaptable to studio, mastering suite or audiophile two-channel playback environments. To accommodate dual-mode systems, we also include a bypass feature that engages a pass-through from a dedicated "Managed Bass Input" on the rear panel, to the CR-1's subwoofer outputs. This makes it convenient to switch from two-channel to multi-channel mode.
CR-1 is the ultimate tool for subwoofer integration.
