SUB 118 SP

The SUB 118 SP enclosure is a high output self-powered sub-bass system equipped with one long-excursion 18” transducer. It is ideal for applications requiring super-powerful sub bass delivery, including live music and dance venues.
This focus and clarity not only enhances the reproduction of program material but also makes the most efficient use of amplifier power. This is a result of Outline’s proprietary ‘E.R.P.’ (‘Energy Retentive Porting’) design. Based on the principles of fluid dynamics and successfully applied to the science of controlling pneumatic forces within a loudspeaker enclosure, this unique arrangement of specially-shaped ports ensures an optimum airflow. This reduces internal turbulence, maximising the efficiency of the transducers and thus allowing more amplifier power to be converted into acoustic energy. Such a design requires high-precision manufacturing techniques, and Outline’s engineering team have applied some original production techniques to turn an exciting concept into a physical reality.
The built-in amplifier platform with four selectable EQ presets and input gain enables to use this enclosure as part of a plug & play solution. The maximum available power from the amplifier module is 2400 W EIAJ at 4 ohm, 4800 W peak.
