The 18 SUB PRO ACTIVE VENTED is a jewel in the pool of subwoofers designed for the highly educated customer that is on the quest for the highest performance and understands how to differentiate sound quality. When this customer experiences the 18 SUB PRO’s unparalleled output and uncolored sound, the measured test results we publish translate perfectly to realized performance.

ASCENDO’s policy is to be completely transparent and publish measurements done by independently certified third-party labs to provide factual data, thereby enabling informed, educated decisions.

The 18 SUB PRO is so far above and beyond the competition in every aspect; refined musicality, tightness, and output levels suitable for a 18″ driver. It is also engineered to operate perfectly in sync (in phase) with our Infrasonic subwoofers: The 24/32/50/80 SUB PRO SEALED when there is a desire to reproduce movie content below 20Hz with the same authority, precision, and musicality.

Compared to conventional subwoofer motor concepts, the ultra-modern double-gap motor of this custom-made 18″” driver with two outer and two inner voice-coils enables more linear travel and much faster directional changes with higher sound power and significantly lower power compression.

Enormous power is achieved with the integrated powerful DSP and amplifier unit. The immensely powerful 1.6kW amplifier and even more powerful power-supply to handle any musical or movie attack with ease.

The 18 SUB PRO ACTIVE VENTED is suitable as a bass system in large home cinema installations or commercial cinemas, for uncompromising demands. We recommend a minimum of 2 subs, but for very large (auditorium / commercial cinema) installations the number may be extended.

The latest generation of highly efficient Class D amplifiers powers the subs. No fan noise can disturb the listening experience because the amps are passively cooled.
