Bass/Midrange 380mm, Tweeter 2 x 25mm Soft Dome. The drivers are similar to those of the Graham Audio LS5/1, which was the studio monitor version of the LS3/1. Unlike the LS5/1, the smaller cabinet features a sealed infinite baffle design. The bass driver has been modified from that of the LS5/1 to achieve a combination of sensitivity and bass response suited to the reduced internal volume. The bass driver is positioned behind a perforated metal plate, whilst the tweeters are mounted on a panel centred in relation to the bass driver. The width of the slot in front of the bass driver is similar to that of the LS5/1 and LS5/5 models and improves the smoothness of the off-axis response. The design adheres to the BBC’s thin-wall principle.
