The 18W/8424G00 from Scan-Speak’s Discovery series is an 18 cm midwoofer designed to deliver an exceptional balance of sensitivity, linearity, and tonal naturalness. Its fiberglass cone with NRSC (Non-Resonant Suspension Coating) technology minimizes resonances and coloration, providing a clear, detailed midrange along with well-controlled bass.
The die-cast aluminum chassis, positioned beneath the spider, ensures a rigid structure free from unwanted vibrations, while the low-damping SBR rubber surround allows for smooth and natural response. Thanks to its high sensitivity of 89.5 dB and nominal impedance of 8 ohms, it is ideal for both high-fidelity two-way systems and high-performance home theater applications.
NRSC-coated fiberglass cone for accurate, resonance-free reproduction.
High sensitivity (89.5 dB) for easy pairing with moderately powered amplifiers.
Die-cast aluminum chassis to minimize structural distortion.
SBR rubber surround for precise excursion control and smooth response.
Excellent midrange performance with clean transitions to highs and lows.
