W/1600 W continuous power rating

• Eight built-in M10 mounting points for overhead suspension

• 15 mm plywood construction for increased cabinet structural integrity

• 4 ohm impedance for efficient amplifier power

• Side mounted hand holds for easy handling during installation

• Foam-lined perforated steel grille

• Barrier Strip and Neutrik SpeakOn ® connection

The SB-118F single 18” and SB-218F dual

18” subwoofers are designed specifically for low frequency enhancement in cinema applications, especially for low frequency content of the surround channels using bass management techniques. A common application is suspending these enclosures from the cinema ceiling in proximity to the wall mounted surround loudspeakers for which the SB-118F/218F provides low frequency enhancement. The SB-118F/218F covers the frequency range from 37 Hz to

230 Hz.

These enclosures are designed for safe and easy suspension using eight built-in M10 fly points. Heavily braced, tour grade 15 mm plywood construction provides great strength while keeping weight to a minimum. The custom 800 watt, 18” transducers were developed especially for cinema use. They feature large 4” (101 mm) voice coils and a multi-vented pole piece to ensure cool operation, even at high power levels. Cooler temperatures increase transducer lifespan and decrease the problem of power compression at high power.

The SB-218F enclosure features separate chambers for each transducer. In the rare event of a transducer failure, this prevents over-excursion of the remaining transducer caused by improper box loading. Both models feature 4 ohm impedance, which means that you can use a smaller amplifier to get maximum output from the loudspeaker.
