Monacor MSH-115HQ Mid-bass woofer

The Monacor MSH-115HQ is a precision-engineered 4-inch mid-bass woofer designed to deliver articulate, detailed low-frequency performance within compact loudspeaker systems. As part of Monacor’s respected HQ series, this driver excels in applications where space is at a premium but sonic quality cannot be compromised. It is ideally suited for use in small sealed or ported enclosures, making it a perfect choice for high-fidelity bookshelf speakers, custom automotive audio installations, or nearfield studio monitors where accurate mid-bass reproduction is essential.

Technically, the MSH-115HQ features an 8-ohm impedance and a sensitivity of 87 dB SPL (1m/2.83V), ensuring efficient power handling and compatibility with a wide range of amplifiers. The driver’s total Q factor (Qts) of 0.55, combined with a resonance frequency (Fs) of 89 Hz and a maximum linear excursion (Xmax) of 3 mm, allows for controlled, distortion-free bass response even at moderate listening levels. The 25 mm voice coil and 5.8 ohm DC resistance contribute to robust thermal management and long-term reliability. With a mounting diameter of 108 mm and a depth of just 64 mm, this woofer integrates seamlessly into slim enclosures, while its 116 mm overall diameter ensures a neat fit. Whether upgrading existing designs or building from scratch, the MSH-115HQ offers a refined, musical foundation for any project demanding clear, detailed mid-bass.
