Edwards Audio SP1 has advanced the design further by the addition of an improved tweeter, as used in the SP2 and optimising the X-over, through the use computer aided modelling and the use of higher quality capacitors and inductors, this has resulted in improved power handling of bass frequencies, a slight improvement in efficiency and improved midband neutrality and openness. We believe that this takes what was already a highly competitive speaker into a market leading position.
