LXstudio

The LXstudio was designed to render sound recordings with clarity, neutrality and with detailed, 3D-like imaging, when properly set up. The speakers will reveal what is in a recording, but never add unpleasantness. 

The LXstudio is 3-way loudspeaker that combines the LXmini with two LXsub4 dipole subwoofers, which have 10 dB higher output capability than can be obtained from the LXmini+2 configuration. A 10 dB increase is perceptually significant due to the ear's very nonlinear hearing sensitivity to the lowest frequencies. With an LR2 crossover at a low 60 Hz the woofers can be placed against the side walls of a room and the LXmini used as near-field monitors. Path length differences to the listener can be compensated for in the DSP unit. Dipole woofers have the advantage of less room mode excitation, which matters even in a highly damped recording/mixing studio.

The LXstudio can be built DIY from a Kit for around $2400, including a miniDSP 4x10HD equalizer/crossover. Additionally, 6 power amplifiers in the 50 W to 200 W range are needed. The frequency range extends from 25 Hz to 20 kHz. The horizontal and vertical off-axis frequency response, which is heard via the room, is spectrally neutral. Thus, listening off-axis merely changes the viewing angle to the phantom acoustic scene rendered by the seemingly absent loudspeakers. 

The LXstudio was designed for a mixing studio application (symphonic music), where the conventional large box monitor loudspeakers gave uneven response, especially at low frequencies, despite the studio being highly damped and relatively large. 

The LXstudio performs sonically like the LX521.4, and comes close to the full-range dipole's ultimate refinement of sound presentation.  ----  SL - 8/16

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?
