The LX521® Reference Loudspeaker has received much applause from music lovers all over the world. But it has also caused disappointment because it requires a fair amount of space and breathing room, which many housings do not provide. On top of that the LX521® is too expensive for some and/or its acoustically defined shape is not pleasing to someone in the household. Such objections are particularly aggravating, when the near live like sound volume capability, for which the LX521® was designed, is neither wanted nor could be tolerated in the given living space, or if they were willing to give up bass below 45 Hz for a much smaller loudspeaker.
LXsirius offers a true alternative to the LX521®, except for the bigger speaker’s extended bass. With a 700 Hz LR2 crossover to a small, full-range and open-baffle driver, and with a diffusing as well as attenuating structure for controlling the rear radiation, the polar response tends towards cardioid behavior and reduces reflections from objects behind the speaker.
With directivity controlled in this way the LXsirius becomes much less sensitive to room placement, while also gaining in 3D imaging precision. The small, full-range driver on top is superbly smooth and detailed. It blends flawlessly with the pistonic, infinite transmission line woofer for a completely neutral sound in a reverberant room. The speaker stands 40″ (1 m) tall.
The LXsirius is a most remarkable loudspeaker. It converts electrical signal voltages into acoustic pressure variations, which are perceived as completely neutral and detailed even in a reverberant environment. With this design, Siegfried Linkwitz wants to give every music lover the opportunity enjoy a reference quality sound system singing in their own living space.
How to set up:LXsirius cannot be setup like a conventinal box speaker. For a good reason. Active Line Level crossovers , where each drive unit is fed by its tailored amplifier, boost LXsirius performance and fidelity.
To pair the best components for these duties -and to minimize cabling in the listening room-, find everything needed between (CD-)player and LXsirius in the PowerBox 6pro NCore precision analog : A precisionASP followed by six channels of NCore® amplification. Six channels mean, that PPowerBox 6pro NCore is prepared to feed added subwoofers (LXsub2 or LXsub4) as well. Multicore cables with 1-click SpeakOn plugs establish an easy and safe connection betwween PowerBox 6pro NCore and LXsirius.
