Rebec M12 Passive Subwoofer

Built around Rebec’s philosophy of natural music reproduction, the M12 is suitable for listeners seeking a fuller low-frequency presentation across a wide range of music genres.

Material Characteristics

The M12 utilizes a semi-relaxed compressed paper cone combined with a modified butyl rubber surround. This construction is designed to provide stable cone movement and reliable low-frequency reproduction.

A 49.5mm voice coil and 140mm ferrite magnet assembly help provide the control and power handling required for subwoofer applications, while the large cone area contributes to increased air displacement.

Sound Performance

According to the Rebec product brochure, the M12 is designed to deliver clean and crisp bass reproduction with good drum density, sufficient bass output, and deep low-frequency extension.

Compared with the M10, the M12 is positioned as a larger-format subwoofer that provides greater low-frequency presence and a stronger sense of bass atmosphere. Its larger cone area allows it to move more air, contributing to increased bass output and a fuller low-frequency presentation.

With a frequency response extending down to 20Hz, the M12 is suitable for systems that require additional low-frequency support while maintaining overall musical balance.

The M12 can be paired with mono amplifiers such as the Rebec D600 and D1200 to create a dedicated low-frequency system.

Design Philosophy

The M12 was developed to provide a practical balance between bass output, low-frequency extension, and musical reproduction. Rather than focusing solely on maximum output, the design aims to deliver bass that integrates naturally with the rest of the audio system while adding depth and weight to music playback.
