ACTIVEBuilt in Amplifier

The SMS G18 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 SMS G18’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 SMS G18 subwoofer 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; SMS G24, SMS G32, SMS G50 and SMS G80 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.

SMS G18 Powered
With built-in powerful DSP and amplification, performance is achieved on a level impossible for externally amplified configurations. The extremely short speaker wires control the subwoofer without added resistance usually found in long cable runs degrading its damping significantly. The immensely powerful 3kW amplifier and even more powerful 6kW Power-supply handle any musical or movie attack with ease. A certified Ascendo Dealer can further optimize the in-room response by manually calibrating the response and tame the room modes efficiently.
