Alpine S2-S40C 4" separate set

The new 2023 S-Series collection
The completely renewed S-Series collection now brings Hi-Res Audio certified speakers to a completely new price range. The speakers have used the design familiar from Alpine's more expensive F#1 Status and R2-Series collections, and the S2-S40C reproduces all the smallest details of the music very accurately and naturally.

Hi-Res Audio certified
Alpine S2-S40C is Hi-Res Audio certified and the treble reproduction of the separate series reaches up to 40kHz. Ease of installation has also been taken into account in the tweeter and very versatile installation accessories are included, and the tweeter is very small in terms of physical dimensions when the mounting adapters are removed, so the installation can be done "in a car like a car".

More accurate playback than before
The S2-S40C mid-bass cone material is a unique combination of polypropylene, glass fiber and mica mica, thanks to which the cone is light and the element can withstand higher powers.

HAMR suspension
Thanks to Alpine's HAMR (High-Amplitude Multi-Roll) suspension, the trajectory of the cone remains linear at all volumes, thanks to which the bass reproduction is very controlled even at higher volumes.

Versatile installation options
The S2-S40C is designed to be installed in the original speaker positions of as many different cars as possible. The tweeter elements have an immersion collar that is removable and the tweeter can be placed in almost all cases instead of the car's original tweeter.
The high-pass filter of the tweeter is integrated into the speaker cable, so the installation of crossover filters does not require separate measures.

Note: Adapters are included, also for the 4″ x 6″ mounting location.
