“…I’ve used dipoles for years (Maggies, Martin Logan, Podium and Quad)
and I thought I understood what an open baffle speaker sounded like.I was wrong, very wrong. Siegfried Linkwitz` term “phantom scene” is
absolutely bang on. I’ve just emerged from 4 hours straight with a broad grin on my face, and am
about to go in for more…..” (Craig, Oxford/UK, LX521 owner)
“The speakers naturally disappear as soon as you start the music; you don’t even have to close your eyes. I would go even further—you have to make a slight mental effort to be aware that the speakers are actually there! It’s uncanny. The precise phantom images produce:d by the LX521 create the most solidly three-dimensional soundstage of any stereo system in my listening experience.” (TheAudioCritic.com, Peter Aczel)
(Mikael K, Sweden on new cascaded ASP with Linkwitz22MG drivers) “..a big difference in transparency and details, and this filter is completely silent if you listen close to the speaker elements. First impression of the new ASP filter was really good! The ASP change was a big upgrade, so I do not know exactly how much difference happened when I also switched to the new midrange L22MG. Can’t tell if ASP of midrange. But the sum is really good. Frank the magician 🙂”
“Just wanted to tell you that that a nephew recently payed me a visit. He had just bought an advanced surround system with B&W speakers and a NAD amplifier. Because of budget restrictions he had to go for the CM9, but during the selection process he listened (blindly) to the store’s best speakers and (unsurprisingly) selected B&W 800 Diamond as the best-sounding. On this background he was completely shocked by the performance of the LX521. First of all he was impressed by the quality of the bass which was the best he ever heard, but also praised the transparent highs and the open midrange. Looking at the price, he declared that this had to be the bargain of the century. .. I am extremely satisfied with my system now,…..thank you (and Siegfried, of course) for the best speaker system I (and my nephew) have ever heard. Kind regards ” (Terje S. Norway, LX521-owner)
Neutral sound, clarity, speed, spatial openness and disappearance from one’s auditory illusion. It renders a superb recording, probably as good as it gets. A highly enjoyable experience.
The LX521® 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.
- V-frame woofers LXsub4 are dull dark anthracite
- Bridges and topbaffles colored in individual custom color or made from precious multilayer birch ply core wood with veneer of choice American Walnut or .
- Panzerholz, Panzerholz/precious veneer and Alu-Panzerholz-Alu topbaffles, are available on special request. Many other wood types are available on request as well: Cherry, Bubinga, Paduk,… ask us via email
- Bridges come with elegant 45deg miters.
LX521® cannot be setup like a conventinal box speaker. For a good reason. Active Line Level crossovers boost LX521 performance and fidelity. Each branch is fed by its tailored amplifier.
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 : A precision crossover, followed by five individual channels of NCore® amplification. Five channels mean, that one PowerBox 6pro NCore is feeding one side of the stereo pair. SpeakON Multicore cables with 1-click SpeakOn plugs establish an easy and safe connection betwween PowerBox 6pro NCore and LX521®.
The V-Frame woofers LXsub4 are 33kg each.
The system -with all woofer drivers installed- usually ships in a 130kg airfreight container.
The insured airfreight rates to the US vary: usually 900-2200€.
