Get big 6×9″ sound in a slim package with the S-6902T 6×9″ thin-mount coaxial speakers, an easy OEM replacement supplied and expertly fitted by Safe and Sound, the vehicle audio and security specialists with over 30 years’ experience.
Full-size 6×9″ sound where depth is tight
The 6×9″ is the classic rear-deck and door speaker, but a full-depth version will not always fit behind a panel or in a shallow rear shelf. The S-6902T solves that. It is a drop-in OEM replacement built on a thin, shallow-mount design, so you get the big, full sound of a 6×9″ speaker in spaces where a standard one simply will not go.
Smooth highs and a deep low end
The S-6902T is a true 2-way coaxial. A 0.75″ pure silk dome tweeter with a neodymium magnet and SEL (Sound Expander Lens) ring gives smooth, refined high frequencies, while the large 6×9″ DDC-coated 2-layer paper cone reaches down to 55 Hz for rich, full mid-bass. The result is a clear, balanced sound from the same head unit and wiring.
Strong, efficient and built to last
With 50W RMS per speaker, 150W peak and 89 dB sensitivity, the S-6902T makes good use of your power and stays clean as you turn it up. An EFF (Efficient Flux Field) motor structure with a 10 oz magnet and a rigid tooled basket keeps the design efficient and solid, while a double-pressed treated foam surround stands up to daily use. The shallow 2.5″ mounting depth is the whole point of this model, and the speakers are supplied as a pair.

- 2-way coaxial with silk dome tweeter – smooth, refined highs.
- 55 Hz to 20 kHz response – rich, full mid-bass.
