LXsirius Turnkey System from www.LINKWITZ.store

LXmini

 

LXsirius is the cosmetically advanced turn-key edition of LXmini. The LXmini 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 is a 2-way loudspeaker, which can be built DIY from a Kit for around $800, including miniDSP 2x4HD equalizer/crossover. Additionally, 4 power amplifiers in the 50 W to 200 W range are needed. The speaker's frequency range extends from 45 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. 

Physics limits the maximum sound level output from a 5 inch woofer below 150 Hz. A gradual, 12 dB/octave low end roll-off provides satisfactory bass extension below 50 Hz. For LXmini+2 I added separate subwoofers for bass extension to 25 Hz. If you plan to upgrade in the future from LXmini to LXmini+2, then use the miniDSP 4x10HD for LXmini.   ----   SL - 8/16

LXsirius+2 System from www.LINKWITZ.store

LXmini+2

LXsirius+2 is the cosmetically advanced turn-key edition of 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

LXstudio Turnkey System from www.LINKWITZ.store

LXstudio

LXstudio from Linkwitz.store is the cosmetically advanced turn-key edition of LXstudio kit version. 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

LX521®.4 System from www.LINKWITZ.store

LX521.4

The LX521.4 exemplifies the best of what I have observed and learned in 50 years of experimentation about rendering stereo recordings in domestic living spaces. I love music. Life's circumstances prevented me from learning to play an instrument, but I make up for it by enjoying the creations of great composers and the art of musicians. I have designed speakers first of all for myself and free of commercial pressures. With the LX521.4 I have arrived at a level of performance, which makes me search no further. Instead I gratefully enjoy what I can hear. I excuse the recording/mixing engineer for his or her imprint and marginal acoustic scene capture, as long as the music still comes through. As hired engineers they work within a set of imposed limitations, one of which is the typical monitor loudspeaker.

The 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. The speakers need breathing room of at least 1 m to the nearest large reflecting surfaces and a room with a minimum floor size of 25 sqm. 

The LX521.4 can be built DIY from a Kit for around $3300, including a miniDSP 4x10HD equalizer/crossover. Additionally, the speaker requires between 8 to10 power amplifiers of 50 W to 200 W.

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?
