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.
