S-12

The S-12 is a compact reflex loaded subwoofer designed to extend the bandwidth and increase the headroom of any of the fullrange loudspeaker models, as well as lend low frequency support in restricted spaces. It consists of a 12” (305mm) high-excursion low frequency driver in reflex loaded enclosure designed to provide smooth LF rolloff and extended bass response.

The drive unit is housed within a compact, vented enclosure constructed from premium 15mm (5/8”) multi-laminate Birch plywood. The S-12 has significant output compared to its footprint, and its compact dimensions enable it to be unobtrusively installed in restricted spaces such as under seating in clubs and bars or flown in ceiling spaces. A total of 14 M10 threaded fixings are incorporated around the enclosure on the top, bottom, sides, and rear for attachment of rigging hardware and safeties. A single flush bar handle, M20 threaded polemount fitting and feet with matching stacking recesses complete the mechanical offering.  The enclosure includes a pair of Neutrik® speakON™ NL4 connectors for input and enclosure link, and a tough mesh-backed stainless steel grille protects the drive unit from damage which can be quickly removed for service purposes.

The enclosure is finished in an impact and weather resistant black or white textured polyurethane finish as standard, though RAL colour matching and enhanced weather-protected outdoor options are available.

The S-12 is designed to provide useful low frequency extension in any application where space is at a premium. The S-12 can support any product, but is especially suitable for reinforcing EMS-41, EMS-51, EMS-61 and EMS-81X loudspeakers, as well as the Reference Series R5.

The S-12 requires external active high/low pass filters and a single amplifier channel to function correctly – as such it is recommended to be used with EM Acoustics’ range of Advanced System Amplifiers. It is however possible to use other DSP-enabled amplifiers, or conventional amplifiers with external DSP. Suitable DSP settings are provided on the EM Acoustics website. The amplifier should be capable of delivering 1000-1400W RMS into an 8-ohm load.
