• High effi ciency subwoofer with two 18" long-throw woofers with special aligner to maintain performance through the years.
• Very high power handling (6000 Watts AES peak) and maximum sound pressure (143 dBSPL peak at 1 metre). Also available in high-power self-powered format with the same possible standard performances.
• The woofers are fi tted in separate chambers to ensure operation even in the event of the breakage of one component; it is possible to connect two different signals, stereo and/or the use of two separate amplifi cation channels.
• Equipped with Outline"s proprietary "Fast Hanger" hanging system for fast reasonably priced flying.
• The cabinet is internally braced to ensure the utmost sturdiness, free from harmful sound "colouring" due to resonance; an optional trolley with sturdy smooth-running wheels facilitates transport, even on relatively uneven surfaces.
• Self Powered featuring the same above performances through a PWM power amplifi er module (AMDF 2KHV-01) fi t inside.

Subtech 218 is a loudspeaker system suited to high-quality sound reinforcement of low and ultra-low frequencies by the use of two by 46 cm. woofers with a special aligner to keep their resonance frequency steady through the years. Loading is of the phase inversion type with the enclosure tuned at a rather low frequency by a long port with a large surface area. Allowing to obtain a wide passband and a considerable extension towards the bottom end of the frequency response. The performance is very high thanks to the careful choice of the refl ex alignment and the construction of the cabinet. The SubTech 218 has a useable frequency
range at -10 dB of from 26 Hz to 500 Hz, while the response is just +/-3 dB from 35 Hz to 350 Hz.

The max sensitivity is 105 dB in half space and the maximum continuous AES power, 1500W gives 134 dBSPL in free-fi eld and 137 dBSPL in half-space, while peak values even reach 143 dBSPL. The front of the cabinet is protected by an anti-resonant steel grille covered with sound-transparent foam. The rectangular cabinet is built in high quality 15mm. Baltic plywood, strengthened by the complex internal structure and suitably positioned internal bracing to eliminate any resonance of the cabinet"s sides.

The black outer fi nish is in high quality scratch-resistant paint. The cabinet has 6 fast fl ying points, that makes vertical or horizontal hanging of numerous units simultaneously extremely easy and reliable, by using the appropriate optional accessories. The front of the enclosure has recessed sockets for fi tting an optional trolley, for handling and protecting the front during transport even on uneven surfaces. Ten recessed integrated handles in the side panels of the cabinet are used for a positive grip during handling.
