That is all the sound comes from a single point source. Upper registers are articulated with flawless precision, whilst the bass drivers maintain authoritative control over the LF – providing undistorted, earth moving realism and accuracy that will awaken your very soul. Open and articulate. Available Piano Black, Walnut, Rosewood, Gloss White $5,600/pair. Dimensions HxWxD: 46.5 x 9.4(14.1w/plinth) x 15.3” Weight: 65 lbs each.
