The Peerless by Tymphany BC25SC55-04 Dome Tweeter is a high-performance 25mm soft dome tweeter engineered to deliver exceptionally clear and detailed high-frequency reproduction. As part of the renowned BC Series, this driver is designed to elevate any loudspeaker project with its refined acoustic character and reliable construction.

Ideal for audiophile-grade bookshelf speakers, two-way monitor designs, or multi-channel home theatre systems, this tweeter excels in applications where precise treble response and low distortion are paramount. Its 4-ohm impedance makes it well-suited for a wide range of crossover networks and amplifier pairings, while the high sensitivity of 93.2 dB at 2.83V/1m ensures effortless dynamic output even with modest amplification.

Technically, the BC25SC55-04 features a silk membrane that provides a smooth, natural sound with excellent transient behaviour. The total Q factor (Qts) of 1.3, combined with a mechanical Q (Qms) of 3.6 and an electromagnetic Q (Qes) of 2.07, indicates a well-damped response suitable for sealed or ported enclosures. With a DC resistance of 3 ohms and a voice coil inductance of just 0.026 mH, this tweeter maintains consistent performance across its operating range. The compact dimensions (70 x 55 mm) and a cut-out diameter of 47 mm facilitate straightforward integration into existing baffles.

This tweeter is a superb choice for builders seeking a refined, high-sensitivity driver that combines technical precision with musicality.
