The Q350 uses a famous technology to great effect, with the Uni-Q drive unit. This involves positioning the treble unit in the middle of the woofer
Made from lightweight yet rigid aluminium, the woofer unit is fast to respond and linear in its response. This helps give life-like dynamics and low levels of distortion.
Early in this review process I realized that Q350 is not the poor person's LS50, but has a unique goodness of its own. The Q350 is a lively and open-sounding loudspeaker.

Warranty : 3 Years.
