Graham LS4/4
From Graham
Derek Hughes developed the LS4/4 out of the LS5/5, the BBC studio speaker built for large control rooms. It keeps that speaker's tweeter and midrange driver but drops to a 270mm bass unit for domestic rooms. The slot loading stays, which holds the focus and widens the sweet spot.
