Graham LS4/4 The Graham LS4/4 designed by Derek Hughes, is a development from our work with the LS5/5. The LS5/5 was a studio speaker designed for large studio rooms at the BBC, and we wanted to include a speaker with similar dynamics for smaller sized domestic rooms. Derek Hughes redesigned the LS5/5 and scaled it down using the same tweeter and mid-range driver but using a smaller bass diver (270mm). The slotted system remains as it gives a superb focus, sound stage and increased sweet spot. The design adheres to the BBC thin wall principle and again as all Graham Audio products is studio grade.   Specifications: System: 3-way, bass reflexVeneer finishesDimensions: (WxHxD): 31 x 110 x 48 cmFrequency Range: 40Hz-20kHz, +/- 2dbImpedance: 8ΩSensitivity: 88db SPL (2.83V, 1M)Max output >103db/pair at 2MBass driver: 270mmMidrange driver: 200mmTweeter: 25m soft domeRecommended amplifier power: 50 to 200 Watt
