Upgrade your motorhome or campervan with the compact Alpine SPC-L350SB Adventure Audio surface-mount speaker. Two ultra-slim carbon-reinforced drivers deliver wide-dispersion sound from a premium black aluminium enclosure that can be installed horizontally or vertically. Rated at 50W RMS and 100W peak, with 6-ohm impedance and a 120Hz–20kHz response.
PLEASE NOTE: The SPC-L350SB package contains one speaker. For a balanced stereo installation, order two speakers. Alpine recommends combining a pair with the SPC-D84L subwoofer system for full-range sound and improved bass performance.
The Alpine SPC-L350SB is a compact black surface-mount speaker developed for motorhomes, campervans and leisure vehicles. Its two ultra-slim carbon-reinforced drivers deliver clear, wide-dispersion sound from a premium aluminium enclosure that can be installed horizontally or vertically.
Conventional car speakers are often installed inside overhead cupboards or positioned facing towards the floor. This can occupy valuable storage space and produce an unfocused sound stage.
Alpine Adventure Audio In-Cabin speakers offer a slimmer and more flexible alternative. The SPC-L350SB can be fitted onto a suitable cabinet, corner, wall or ceiling surface and directed towards the listening area for clearer cabin sound.
Installs onto a suitable interior surface without requiring the large aperture needed for a flush-mounted speaker.

The black aluminium enclosure and stainless-steel grille complement modern motorhome and campervan interiors.
The 6-ohm speaker can be powered by a compatible head unit or combined with a suitable external amplifier.
The carefully tuned two-driver array delivers smooth, detailed sound while maintaining a compact and discreet profile. The speaker handles 50 watts RMS and up to 100 watts peak power.

Their compact construction provides clear cabin sound without the depth requirements of many conventional car-audio speakers.
