Outline SUB118 Ground-stackable Subwoofer 1 x 18″
When your venue or tour demands seismic bass energy without sacrificing footprint, the Italian-built Outline SUB118 answers with explosive 142.5 dB SPL peaks and controlled 35 Hz extension. Crafted for live music, dance clubs and rental inventories, this compact powerhouse transforms amplifier watts into audience-moving acoustics with unmatched efficiency.
Ground-shaking output, compact form
An advanced long-excursion 18″ transducer sits at the heart of the SUB118, producing deep, punchy low frequencies that stay articulate even at maximum output. Its quasi-omnidirectional radiation pattern blankets crowds evenly, while the enclosure’s stackable design simplifies deployment in cardioid or conventional arrays.
E.R.P. technology for superior efficiency
Outline’s proprietary Energy Retentive Porting (E.R.P.) channels airflow using fluid-dynamics principles. By minimising internal turbulence, more amplifier power is converted into acoustic energy—delivering louder, cleaner bass with the same amplifier channel. The result is tighter transient response and reduced port noise, even during demanding EDM drops or live kick-drum transients.
Built to thrive on the road
The SUB118’s 15 mm Baltic birch cabin is enveloped in an ultra-tough black polyurea coating that resists scratches, moisture and impact. A steel, epoxy-coated grille protects the driver, while 16 × M8 points and twin M20 pole mounts provide versatile rigging. At just 47 kg, it’s easily maneuvered yet engineered to withstand years of tour abuse.
