About the IB2i

The PMC IB2i is a three-way, high-resolution reference monitor designed for professional and audiophile use. It features a 10-inch carbon fiber/Nomex flat-piston bass driver with a 3-inch voice coil and an oversized roll surround for long excursion, driving an 8-foot transmission line filled with foam to absorb upper frequencies and maintain air pressure for low distortion and extended bass response down to 25Hz. The midrange is handled by a 3-inch PMC fabric dome driver, and the high frequencies by a 1.1-inch fabric soft dome driver. The crossover points are at 380Hz and 3.8kHz, using 24dB/octave Linkwitz-Riley networks built on military-grade fiberglass circuit boards with hand-selected components. The speaker has a sensitivity of 89dB/W/m, a nominal impedance of 4 ohms, and can handle amplification from 180W up to 900W. It is known for its neutral, uncolored sound with excellent imaging, speed, and bass resolution, making it a favorite in professional studios and among discerning audiophiles. The cabinet dimensions are approximately 29.1" H x 13" W x 18.3" D, weighing about 90 lbs. The rear panel includes tri-wiring or tri-amping binding posts. The IB2i is available in finishes such as Cherry and studio black ash. It is no longer in production but remains highly regarded for its transparency and dynamic performance.
