Peter lyngdorf, founder of Denmark’s Steinway Lyngdorf, enjoys a near-godlike reputation in the audio industry. For much of his career he has worked to create home-audio systems with ‘absolutely no restrictions or limitations’. With the Steinway Lyngdorf LS Sound System, he has achieved this goal. The LS surround module is a 3-way design with one inch woofer, two 5-inch mids and one AMT mounted sideways.
Among its super-expensive speaker offerings is the LS line, a modular in-wall system based on the concept of a line source, in which a vertical stack of drivers delivers smooth horizontal dispersion and sound levels that fall off more gradually with distance than point-source speakers. As a result, the difference in volume between the front and back rows is less than it otherwise would be.
The LS front left and right modules are mirror images of each other with three 5-inch midrange drivers and two AMT (air-motion transformer) ribbon tweeters. Frequency response is specified to extend from 80Hz to 22kHz, and they can pump out up to 124dB SPL at a distance of 1 meter. Serving the center channel is the LS Center module, which has the same number and type of drivers and the same performance specs as the front left and right modules.
The LS Surround module is a 3-way design with one 8-inch woofer, two 5-inch mids, and one AMT mounted sideways and firing into twin acoustic channels to diffuse the highs for more enveloping surround sound. The frequency response is spec’d from 80Hz to 18kHz with a maximum sound level of 110dB SPL at 1 meter. At the bottom of the frequency spectrum, we find the LS Boundary Woofer with two 12-inch drivers in a sealed cabinet. Its frequency response extends from 500Hz down to 20Hz with a maximum sound level of 112dB SPL at 1 meter.
A complete LS system includes the P1 surround processor, which can decode all the currently available surround formats, including Dolby TrueHD and DTS-HD. It also offers automatic room correction, bass management, and level and delay alignment in addition to a host of other advanced features. Audio power for the system is supplied by a rack of A1 digital power amps, each providing two channels at 400Wpc. The amps are fully integrated with the speakers and processor—in fact, you can’t buy one without the others.
A customer can configure his multiple speaker modules in columns of two, four or six depending on the size of the room and bank account. If you set up a 5.1 system with eight front modules (four right, four left), four centre modules, four surround modules, four sub modules, one P1 processor, and nine A1 amps, it will set you back $267,000. Whereas, if you go for a massive 7.1 system with 12 fronts (six on each side), six centres, 36 surrounds, 24 subs, and all the necessary electronics, you will have to shell out a whopping $993,ooo.
Each Steinway Lyngdorf LS needs to be installed by Steinway Lyngdorf’s engineers and custom calibrated to the room.
