12L Active

About the 12L Active

The Quad 12L Active is a 2-way, 2-driver active loudspeaker system designed primarily for studio use and high-fidelity listening. It features a 170mm cone bass driver and a 25mm dome tweeter, with built-in amplifiers matched to the drivers for optimal performance and protection. The frequency response ranges from 45Hz to 28kHz at 3dB, with a sensitivity of 88dB SPL at 1 meter for 2.83V input. It is recommended to be driven by amplifiers or sources delivering 30 to 200 watts. The speakers include balanced inputs for noise immunity and level controls for output matching. The cabinet dimensions are approximately 340mm high, 205mm wide, and 253-355mm deep, with a polished black or silver finish. The design emphasizes neutral, detailed sound with good integration between drivers, suitable for near-wall placement or on stands. Protection circuitry is included to prevent damage at high output levels, indicated by a front LED. The 12L Active is regarded as a mature, well-built monitor speaker with a clear improvement over the smaller 11L Active model.
