Monacor SP-4/60PRO 4'' PA Midrange Woofer

The Monacor SP-4/60PRO is a professional 4-inch PA midrange woofer designed to deliver articulate and powerful mid-band reproduction in a variety of sound reinforcement applications. Engineered for clarity and efficiency, this driver excels in live sound setups, installed PA systems, and custom speaker cabinets where precise vocal and instrumental presence is essential. Its compact footprint makes it an ideal choice for line arrays, stage monitors, and compact enclosures where space is at a premium but performance cannot be compromised.

At the heart of the SP-4/60PRO lies a paper cone diaphragm, chosen for its natural, warm tonal characteristics and low mass, ensuring responsive transient behaviour. The ferrite magnet assembly provides a robust magnetic circuit, contributing to a sensitivity of 90 dB SPL (1m/2.83V) for efficient power handling. With a total Q factor (Qts) of 0.6, this driver offers a balanced blend of mechanical and electromagnetic damping, making it suitable for both sealed and ported enclosure designs. The voice coil inductance is a low 0.3 mH, aiding high-frequency extension, while the DC resistance measures 6.76 ohms. Measuring 113 x 113 mm with a mounting depth of 63 mm and a cut-out diameter of 103 mm, the SP-4/60PRO is straightforward to install using its four fixing holes. Whether for upgrading existing systems or building new projects, this Monacor driver delivers reliable, high-quality mid-range performance.
