Peerless by Tymphany GBS-250F38CP01-04 Subwoofer

The Peerless by Tymphany GBS-250F38CP01-04 10" Shallow Subwoofer delivers exceptional low-frequency performance without demanding excessive installation depth. Designed for audio enthusiasts who require powerful bass in space-constrained environments, this 4 Ohm subwoofer is ideal for custom car audio builds, under-seat installations, or slim home theatre enclosures where traditional deep-frame drivers simply cannot fit. Its robust engineering ensures that even in compact sealed or ported boxes, you achieve tight, controlled, and impactful bass reproduction.

At the heart of this driver lies a carefully optimised motor system, featuring a total Q factor (Qts) of 0.51, which balances transient response and low-end extension. The 21.5mm linear excursion (Xmax) enables significant cone movement for deep bass output, while the 88.3dB sensitivity at 2.83V/1m ensures efficient power handling. The voice coil inductance (Le) of 2.81 mH and DC resistance (Re) of 3.6 Ohms contribute to stable electrical performance. With a mechanical Q (Qms) of 8.3 and an electromagnetic Q (Qes) of 0.544, the subwoofer offers controlled damping for accurate bass articulation.

The shallow 40.3mm mounting depth and 229mm cutout diameter allow versatile placement, while the eight-hole mounting pattern on a 251mm bolt circle ensures secure installation. With a nominal diameter of 254mm, this subwoofer is a superb choice for anyone seeking high-quality, space-saving bass.
