The SB12PFCR25-4 Paper Bass-midwoofer from SB Acoustics is a high-quality 4-ohm driver designed to deliver clear, detailed bass and midrange response in a variety of audio applications. Its lightweight paper cone and low-loss suspension system ensure natural, uncoloured sound reproduction, making it an excellent choice for both DIY speaker builders and professional audio designers.
This versatile bass-midwoofer is ideal for use in compact two-way bookshelf speakers, small subwoofer systems, or as a dedicated mid-bass driver in multi-way designs. With a nominal diameter of 122 mm and a mounting depth of just 71.3 mm, it fits neatly into enclosures where space is at a premium, while its 87 dB sensitivity (1m/2.83V) allows for efficient power handling and good output from modest amplifiers.
Technically, the SB12PFCR25-4 features a plastic basket for reduced resonance and a 4-hole mounting pattern for secure installation. Its impedance is 4 ohms, with a DC resistance (Re) of 3.1 ohms and a voice coil inductance (Le) of 0.26 mH. The driver’s Thiele-Small parameters include a total Q (Qts) of 0.43, a mechanical Q (Qms) of 3.4, and an electrical Q (Qes) of 0.49, with mechanical losses (Rms) of 0.6. These specifications combine to offer controlled, articulate bass with good transient response.
Whether you are upgrading an existing design or starting a new project, this SB Acoustics paper cone driver delivers reliable performance and natural sound quality.
