Rebec M8 Passive Subwoofer
Product Overview
The Rebec M8 is an 8-inch passive subwoofer developed for car audio systems that require stronger low-frequency performance while maintaining good control and musical balance. With a 250W RMS power rating, dual 2Ω voice coils, and a high-excursion design, the M8 is suitable for a wide range of system configurations.
Designed according to Rebec’s philosophy of natural music reproduction, the M8 focuses on delivering clean bass response, good impact, and low-frequency extension for everyday listening.
Key Features
• 250W RMS power handling
• Dual 2Ω voice coil design
• High-excursion suspension with 15mm Xmax
• Semi-relaxed compressed paper cone
• Modified butyl rubber surround
• Large 140mm ferrite magnet structure
• Suitable for sealed and ported enclosure applications
Material Characteristics
The M8 uses a semi-relaxed compressed paper cone combined with a modified butyl rubber surround. This combination provides a balance between rigidity and damping, helping the driver maintain stable low-frequency reproduction.
A 140mm ferrite magnet assembly and 49.5mm voice coil contribute to the driver’s ability to handle power while maintaining control throughout its operating range.
Sound Performance
The Rebec M8 is tuned to provide clean and crisp bass reproduction with good drum impact and sufficient low-frequency output. Its design supports deep bass extension while maintaining clarity and definition in the lower frequencies.
Compared with the RU8, the M8 is positioned as a solution that offers greater bass presence and stronger impact. It is suitable for listeners who want additional low-frequency energy without overwhelming the overall balance of the audio system.
The M8 can be paired with mono amplifiers such as the Rebec D600 and D1200 to build a complete low-frequency system.
Design Philosophy
The M8 was developed to provide a practical balance between output capability, 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 and supports a wide variety of music genres.
