LXmini+2

The LXmini+2 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. You will get lost in the music and have a big smile on your face, guaranteed!

The LXmini+2 is a 3-way loudspeaker, which can be built DIY from a Kit for around $1800, including a miniDSP 4x10HD equalizer/crossover. Additionally, 6 power amplifiers in the 50 W to 200 W range are needed.  The speaker's 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. 

With an LR2 crossover at a low 60 Hz the two subwoofers can be placed next to or against the side walls of a room. Path length differences to the listener can be compensated for in the DSP unit. Dipole woofers can also be angled to reduce room mode excitation and thus preserve articulation in bass sounds.

The LXmini+2 performs sonically like the LX521.4 and comes close to the full-range dipole's ultimate refinement of sound presentation, though at 10 dB reduced volume levels in the bass.    

(An upgrade from LXmini to LXmini+2 requires addition of two LXsub2 subwoofers, a stereo power amplifier (2x 50 W min), and a miniDSP 4x10HD)  ----   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?
