Scan-Speak Revelator 15W/8530K00 Midwoofer

The Revelator 15W/8530K00 5.5'' Midwoofer from Scan-Speak represents a pinnacle of engineering for discerning audio enthusiasts. Designed to deliver both articulate midrange and controlled bass, this driver is an ideal choice for high-fidelity two-way or multi-way loudspeaker systems. Its compact footprint makes it particularly well-suited for bookshelf monitors, stand-mount designs, or as a dedicated midbass unit in larger configurations where space is at a premium but performance cannot be compromised.

At the heart of this driver lies a robust ferrite magnet motor, paired with a lightweight cone assembly that ensures rapid transient response and low distortion. With a sensitivity of 86 dB SPL at 2.83V/1m, it offers excellent efficiency for its class. The motor system is complemented by a low voice coil inductance of 0.3 mH, contributing to extended high-frequency response and clean power handling. The driver’s Thiele-Small parameters reveal a well-damped character: a total Q (Qts) of 0.39, with a mechanical Q (Qms) of 5 and an electrical Q (Qes) of 0.43, indicating suitability for both sealed and vented enclosures. A maximum linear excursion (Xmax) of 6.5 mm allows for meaningful bass output without sacrificing control.

Precision-engineered for seamless integration, this midwoofer features a nominal diameter of 139.7 mm, a mounting depth of 77 mm, and a cut-out diameter of 125 mm, secured by five mounting holes. The DC resistance (Re) is 5.85 ohms, ensuring compatibility with typical amplifier loads. Whether you are building a reference-grade loudspeaker or upgrading an existing design, the Revelator 15W/8530K00 delivers the clarity and authority that define Scan-Speak’s renowned legacy.
