PowerBass 4" Coaxial OEM Speaker S-Series

4" OEM drop-in replacement

The PowerBass S-Series 4-inch coaxial speaker fits factory openings without modification. A pure silk dome 3/4-inch tweeter with a neodymium magnet produces smooth treble. The two-layer paper cone with Dynamic Damping Coating reduces distortion and adds UV protection. A double-pressed, UV-treated foam surround and non-resonant steel basket keep audio reproduction accurate.

Ideal for factory speaker swaps

Owners replacing worn OEM units in 4-inch locations will appreciate the direct fit and efficient flux field motor that delivers louder output with less power. Buyers needing component separates, larger cone areas or specific impedance matching should look at other lines. The S-Series range also includes 2.75-inch, 5.25-inch, 4x10-inch, 6.75-inch and 6x8-inch models for different openings.

Handles daily listening with headroom to spare

The efficient motor structure provides ample volume for typical cabin levels while running cool on modest amplifier power. At extreme volumes or with heavy bass EQ the 4-inch cone reaches its excursion limit and distortion rises. For high-SPL competition or sub-bass duties a larger driver or dedicated subwoofer is required.
