Designed for discerning listeners, this dedicated dome tweeter ensures that every cymbal crash, vocal sibilant, and string shimmer is rendered with remarkable precision, transforming your in-car listening experience into something truly immersive.

Ideal for use in custom car audio installations, this tweeter excels when paired with compatible midrange drivers and woofers to create a cohesive, full-range soundstage. Whether you are building a competition-grade system or simply seeking to enhance your daily commute, the R1904/613001 integrates seamlessly into door panels, dashboards, or A-pillars, offering flexibility for both novice enthusiasts and seasoned installers.

Technically, this 19mm dome tweeter features a total Q factor (Qts) of 1.61, ensuring controlled damping and smooth frequency response. With a 4-ohm impedance and a DC resistance (Re) of 3.3 ohms, it is easy to integrate with standard car audio amplifiers. The sensitivity of 87 dB (SPL 1m/2.83V) guarantees efficient power handling, while the low voice coil inductance (Le) of 0.02 mH contributes to extended high-frequency extension. The resonance frequency (Fs) of 1 kHz further supports accurate treble reproduction, and the 39 mm cut-out diameter simplifies installation.

In summary, the Scan-Speak Discovery R1904/613001 is a precision-engineered component that elevates automotive audio with its refined technical specifications and build quality.
