  LX521.4 - Reference Loudspeaker

LX521.4 is a 4-way loudspeaker, designed as full-range dipole, for flat on-axis and off-axis response in the horizontal plane and frontal hemisphere. It requires between 8 to10 power amplifiers of 50 W to 200 W and a miniDSP 4x10HD. The speakers need breathing room of at least 1 m to the nearest large reflecting surfaces and a room with a minimum volume of 65 m3

The LX521.4 eliminates the passive L&C crossover in the LX521 top baffle and brings the speaker to its logical completion. Drivers and baffle design remain unchanged. Equalization and crossovers have been redesigned from newly taken acoustic measurements for a lower listening  axis. 

With its clarity, imaging, high dynamics and disappearance from one's auditory illusion, the LX521.4 renders a superb recording probably as good as it gets and delivers a highly enjoyable experience. I am delighted.

At the "Reproduced Sound 2015" Conference of the the UK Institute of Acoustics I gave a talk "The Magic in 2-Channel Sound Reproduction - Why is it so rarely heard?"

What you hear is not the air pressure variation in itself 
but what has drawn your attention
in the streams of superimposed air pressure variations 
at your eardrums

An acoustic event has dimensions of Time, Tone, Loudness and Space
Have they been recorded and rendered sensibly?
