Volt Loudspeakers SB2550 Subwoofer

The SB2550 Subwoofer from Volt Loudspeakers is a precision-engineered driver designed to deliver deep, controlled low-frequency extension for high-fidelity audio systems. With its 254mm nominal diameter and robust aluminium basket, this subwoofer combines exceptional build quality with outstanding acoustic performance, making it an ideal choice for audiophiles and professional installers alike.

This subwoofer excels in a variety of applications, from dedicated home theatre setups to high-end stereo music systems where accurate bass reproduction is paramount. Its low resonance frequency of 21Hz and impressive linear excursion of 11mm enable it to produce powerful, articulate low notes without distortion, whether used in sealed or ported enclosures. The 8-ohm impedance ensures compatibility with a wide range of amplifiers, while the 88dB sensitivity provides efficient power handling.

Technically, the SB2550 features a total Q factor of 0.29, indicating a well-damped response ideal for tight, controlled bass. The electromagnetic Q of 0.34 and mechanical Q of 1.9 work together to minimise unwanted resonances, while the DC resistance of 6 ohms and voice coil inductance of 1.46mH contribute to stable electrical performance. The aluminium basket not only reduces weight but also enhances heat dissipation, ensuring reliability during extended use.

In summary, the Volt SB2550 Subwoofer offers a compelling blend of technical sophistication and practical performance, delivering the low-frequency authority required for truly immersive audio experiences.
