Description

Eminence SD28 1″ Soft Dome Tweeter, 4 Ohm, 10W is an ultra-compact high-frequency speaker designed to deliver smooth, extended treble reproduction in space-constrained audio applications. The SD28 features a 4-ohm nominal impedance, 10W AES power rating, 20W EIA rating, 92.5 dB sensitivity, and a usable frequency range of 1.5 kHz to 20 kHz.

With an overall diameter of only 1.48 inches, the Eminence SD28 is well suited for home stereo, car audio, ATV, RV, compact speaker systems, and custom audio projects where a small-format tweeter is required. Its 1.5 kHz resonance and 1.5 kHz recommended low crossover frequency allow it to provide high-frequency coverage in a compact package.
