Wisdom Audio Sage Series C150

The C150 carries the same planar magnetic line source technology as the L75 and L150 in a more compact 50-inch height, with two woofer arrays behind it totalling sixteen high operating pressure drivers — output Wisdom equates to a 15-inch woofer.

Fifty inches is the height that fits under most screens, which is the practical reason this model exists. It gives a centre channel genuine line source behaviour, and therefore the same freedom from floor and ceiling reflection as the mains flanking it, in a chassis that clears the bottom of the picture.

The in-wall C150i takes a slim paintable grille or a custom size cut to a design element; the on-wall C150m is finished to match. Like the rest of the Sage line sources it needs outboard DSP and active crossover rather than running from a single amplifier channel.
