JL Audio JX250/1 Class A/B Monoblock Subwoofer Amplifier Review

JL Audio JX250/1 Class A/B Monoblock Subwoofer Amplifier Feature

• Rated Power 14.4 V: 175W x 1 @ 4 ohm // 250W x 1 @ 2 ohm
• THD at Rated Power: 1% @ 4 ohms
• Frequency Response: 10 Hz - 150 Hz +/- 1.0 dB
• Input Range: 200mV - 4V RMS (Low-Level) // 2.0V - 10V RMS (High-Level)
• Subwoofer Crossover: 12 dB/octave with continuously variable cutoff frequency selection from 50 - 200 Hz. Non-defeatable.

When you see a moderately priced amplifier loaded with chrome and lights, you know that the money to pay for the bling came from somewhere, and that 'somewhere' is under the hood. By contrast, when you inspect a JL Audio JX amplifier, you will see that nothing is spent on gimmicks, blue lights or chrome. Instead, we apply our no-nonsense, pure performance philosophy to specify oversized output transistors and rugged MOSFET power supplies that ensure ample current and thermal capacity. These beefy parts operate well under their limits to deliver stable performance and vastly better reliability than the wimpy devices commonly found in many competing products. It all adds up to solid bass definition and cleaner, louder high frequency output that gets the most out of your speaker system. To get your system dialed in just right, we also include flexible signal processing capabilities with fully variable crossover filters, pass-through preamp outputs and a Bass EQ. The monoblock models also include a port for an optional Remote Level Control. Active Crossover Features Fully variable 12dB/octave filters controls offer excellent tuning flexibility. Remote Bass Level Monoblock models also feature the ability to control the bass level from the front seat with an optional RBC-1 Controller (sold separately). Hi-Level & Low-Level Inputs JX amplifiers have both Hi-Level (speaker level) and Low-Level (pre-amp level) inputs for maximum installation flexibility. Class D Amplifier Circuit The JX1000/1D employs an advanced Class D switching design that allows it to produce 1 kilowatt of clean subwoofer power while drawing significantly less current from your electrical system and generating less heat than a conventional Class A/B or Class B design. Preamp Outputs Pass-through pre-amp outputs permit interconnection of multiple amplifiers. High-Mass Heatsink. Rugged MOSFET Switching Power Supplies.
