About the LB1
The PMC LB-1 is a 2-way, 2-speaker transmission line system studio monitor featuring a 27mm silk soft-dome tweeter and a high power 110mm woofer with a massive 75mm voice coil. It delivers a useable frequency response from 35Hz to 25kHz, with a peak SPL of 114dB at 1 meter and a sensitivity of 87-89dB (1W/1m). The LB-1 is designed for applications requiring reference-quality, full-range monitoring in limited spaces, such as audio/video edit suites, home and project studios, and classical music recording. It has a tall, thin cabinet profile (180mm wide, 534mm high, 268mm deep) and weighs approximately 8.5kg. The speaker is magnetically shielded, allowing use near video monitors. The crossover frequency is 2.5kHz, and it has a nominal impedance of 4 ohms, recommended for amplifiers up to 300W. The LB-1 is available in several versions including Classic, Signature (with technical improvements and signed certificate), magnetically shielded LB1M, and a horizontal center channel LB1C for surround systems. It is praised for its transparency, clarity, resolution, and consistent stereo imaging over a wide listening area, with a neutral tonal balance and convincing dynamic contrasts. The cabinet is constructed from 12mm MDF with internal damping and acoustic absorbent materials for reduced resonance.
