A purpose-built 8-inch long-excursion driver, built on JL's DMA motor optimization, sits in a sealed cabinet just over 11 inches tall, powered by a 500-watt Class D amplifier with a tightly regulated switching power supply. Line and speaker-level inputs and a 24 dB\/octave Linkwitz-Riley low-pass filter make it simple to add to almost any system.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 20px\"\u003eIt's built for small rooms, desktop systems and compact bookshelf speakers that need help below 50 or 60 Hz, and it reaches 29 Hz at −3 dB. The sealed box keeps bass quick and tidy rather than boomy, which matters with music. It has no built-in room correction, so placement and the phase and crossover controls do the work. For a bigger room or more output, step up to the d110 or an E-Sub.\u003c\/p\u003e\n\u003ch3 style=\"margin:0 0 8px;font-size:16px\"\u003eKey technologies\u003c\/h3\u003e\n\u003cul style=\"margin:0 0 20px;padding-left:18px\"\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eDMA-optimized driver.\u003c\/strong\u003e A purpose-engineered long-excursion driver built on JL Audio's DMA motor optimization, for lower distortion at high output.\u003c\/li\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eClass D amplifier.\u003c\/strong\u003e Tightly regulated switching power supply, so it keeps going where most small subs run out of power.\u003c\/li\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eSealed enclosure.\u003c\/strong\u003e No port, so no port noise, and bass that starts and stops quickly.\u003c\/li\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eFlexible hookup.\u003c\/strong\u003e Line and speaker-level inputs and a 24 dB\/octave Linkwitz-Riley low-pass filter, variable from 25 to 130 Hz.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"margin:0 0 8px;font-size:16px\"\u003eFinishes\u003c\/h3\u003e\n\u003cul style=\"list-style:none;margin:0 0 6px;padding:0\"\u003e\n\u003cli style=\"display:flex;align-items:center;gap:10px;margin:0 0 6px\"\u003e\n\u003cspan style=\"flex:0 0 18px;width:18px;height:18px;border-radius:50%;background:#2e2a27;border:1px solid #d8d5ce\"\u003e\u003c\/span\u003e\u003cspan\u003e\u003cstrong\u003eBlack Ash\u003c\/strong\u003e \u003cspan style=\"color:#55524c\"\u003eblack ash vinyl veneer\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"display:flex;align-items:center;gap:10px;margin:0 0 6px\"\u003e\n\u003cspan style=\"flex:0 0 18px;width:18px;height:18px;border-radius:50%;background:#0d0d0d;border:1px solid #d8d5ce\"\u003e\u003c\/span\u003e\u003cspan\u003e\u003cstrong\u003eGloss Black\u003c\/strong\u003e \u003cspan style=\"color:#55524c\"\u003ehigh-gloss black\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"margin:0 0 20px;font-size:13.5px;color:#55524c\"\u003eSupplied with a grille.
