The 18-2 PRO SUB Passive Sealed Shallow is a dual 18″ passive cinema / hifi subwoofer, in a sealed enclosure, tuned to fit the ASCENDO speaker series for an uncompromising cinema / hifi experience.

The 18-2 PRO SUB Passive Sealed Shallow subwoofer is so far above and beyond the competition in every aspect; refined musicality, tightness, and output levels suitable for a 18″ driver. Combine this exceptional performance with an enclosure only 10,43” deep to accommodate a wider range of applications where larger enclosures just can’t fit, and this model could possibly take the home theater market by storm.

The 18” driver is an advanced carbon rohacell composite sandwich cone. It is coupled with a neodymium motor with 4” Ultra-high-temperature voice coil. With a max SPL of 137dB @100Hz, the dynamic expression and percussive impact that this sub can deliver puts it in a class by itself, let alone in such a shallow footprint as to almost disappear in home theaters or media rooms when compared to more traditional cube subwoofer designs.

The 18-2 PRO SUB Passive Sealed Shallow is engineered to operate perfectly in sync (in phase) with our Infrasonic subwoofers; The24, The32, The50 and The80 when there is a desire to reproduce movie content below 20Hz with the same authority, precision, and musicality. The combined results sound (and feel) like seamless and natural extensions of their individual efforts, adding to the overall addictive, immersive quality of a complete ASCENDO system.

We recommend 2 subs in medium-sized installations, and for larger installations the number may be extended.

All ASCENDO loudspeakers can be combined with the subwoofer and are particularly suitable for modern 3D applications on the basis of Dolby ATMOS, Auro-3D, DTS:X and IMAX Enhanced.
