The NEOS PX COMPACT sub-woofer allows multi-way systems of various output power and frequency response to be created when combined with any of the NEOS PX Series satellites. It features an 18” speaker with ISV voice coil and Double Silicon Spider suspensions, which can optimize mechanical excursion and preserve system linearity. Double Demodulating Rings grant low distortion and an excellent sound quality. The 18mm birch plywood cabinet is fitted with four rugged 80mm wheels for an easy transport. For a correct filtering, EQ and alignment of the passive version, we recommend the use of PROEL PC260 digital processor that provides the same high-performance processing as the built-in DSP in the active versions.
