MODEL 10 Electrostatic Speaker
Roger Sanders built his first ESL (Electrostatic Loudspeaker) in 1972. He quickly appreciated the superior performance that a massless electrostatic offered over conventional magnetic speakers with regards to low distortion, lack of resonances, and incredible detail. But their problems of limited output, inability to produce deep powerful bass, and unreliability have kept him busy improving them over the last 30+ years.
The result of this lifetime of work is that Sanders Sound Systems ESLs are the only ones to have solved all the problems and limitations of ESLs. Roger's "Ultrastat" panels will play at ear-bleeding levels, cannot be arced, do not use or need protective circuitry, are immune to humidity, dust, and dirt, and do not need or use dust covers. They can be driven by multi-thousand watt amplifiers without damage. They are more rugged than conventional magnetic drivers. They do not fail and are so robust that they come with a lifetime warranty.
The Model 10 electrostatic speaker is Sanders' flag ship. It is the best speaker Roger knows how to make after 30+ years of research, design, and testing of electrostatic speaker. This is simply a no-compromise electrostatic speaker that solves all the problems that plague other electrostatic speakers.
The Model 10 will play at concert hall levels and can be used with multi-thousand watt amplifiers without arcing or damage. No protective circuitry is used or needed. It will reproduce the full dynamic range of any music without strain. Deep powerful bass is assured with the use of a transmission line woofer system. The woofer system has been specifically designed to stop and start faster than other woofers so that perfect integration with a massless ESL finally is achieved.
Passive crossovers are not used as they are seriously flawed and degrade the performance of any speaker. Expensive electronic crossovers and biamplification are used to achieve spectacular levels of performance.
This speaker practically disappears into the room, both sonically and visually. This helps with the age old problem of the speakers taking over the room. This integrated speaker system will be a worthy anchor of a reference-level high-end audio system of the highest performance possible.
Our Latest Design is our Model 10e Electrostatic Speaker
This price includes:
- Electrostatic Speakers with 1) aluminum bass driver and 2) revised transmission line
- Magtech Amplifier
- New LMS (Loudspeaker Management System) includes digital crossover with a Room Correction System, Digital Signal Processor, and Real Time Analyzer
Sanders Sound Systems has been producing the most advanced and sophisticated speakers available for many years. We do not compromise. We use only the best technology, which includes electrostatic midrange/treble, transmission line bass, digital electronic crossovers with electronic time alignment, and biamplification using the unique, voltage-regulated, Magtech amplifier.
However, a truly State-of-the-Art loudspeaker must also include an RCS (Room Correction System) since even a perfect loudspeaker will have its frequency response degraded by the room/speaker interaction and bass resonances produced by room dimensions. Any speaker that does not use an RCS is simply not performing to its full potential.
Additionally, a S.O.T.A. speaker needs a DSP (Digital Signal Processor) so that the user can tailor the speaker's frequency response to compensate for deficiencies in recordings and to best match his personal preferences in how his speaker system should sound.
An S.O.T.A. speaker needs an RTA (Real Time Analyzer) so that the user can actually measure the frequency response of his speakers and room. Only then can he have the information needed to actually know how to adjust the frequency response of his system -- instead of just guessing and trying to optimize it "by ear."
When all these features are combined with a modern, digital crossover, the resulting component is called an LMS (Loudspeaker Management System). Unfortunately, there has been no comprehensive, simple to operate, self-contained, practical, and automated LMS available until recently.
Sanders Sound Systems has finally developed the first, truly S.O.T.A. speaker using all the technology and features available in an LMS in the new Model 10e speaker system. The Model 10e does not require an outboard computer to operate, has an automated RCS, includes an independent RTA, and makes it possible for the owner to infinitely tailor the frequency response of the audio system to whatever degree he feels necessary.
When these advanced electronic features are combined in an electrostatic loudspeaker with transmission line woofer system, the result must be heard to be believed.
The Model 10e speaker is now available for immediate delivery. The price is only $17,000, which includes electrostatic speakers, aluminum transmission line woofer systems, the new LMS, and a Magtech amplifier that can be used for powering either the panels or the woofers.
This is truly a State-of-the-Art loudspeaker system that has no peer. Try it using our 30-day, risk-free, in-home trial, which applies to customers everywhere in the world.
Sanders Sound hits the Sweet Spot - AudiogoN
"Roger Sanders, inventor of the curved electrostatic loudspeaker, will make you rethink everything you always thought you knew about stats. He sure did (rethink everything) to the point of abandoning his own invention for a contradictory philosophy. His logic is irrefutable, his speakers are infallible, and his electronics are unstoppable. Check out this video for a crash course on electrostatic myths and mating." - AudiogoN
A major part of his work was devoted to dealing with the issue of high frequency "beaming" in large, planar loudspeakers. To deal with this issue, he invented the free-standing, curved, electrostatic panel. This made it possible to widely-disperse the high frequencies from a large ESL. He published this invention in Speaker Builder Magazine in 1980. The Martin Logan company adopted his technique in their ESLs.
Roger expected that his wide-dispersion, curved panels would perform better than narrow-dispersion, planar speakers. But he discovered that the curved panel was inferior to a planer one with respect to transient response, imaging, frequency response, speaker placement, and output. These problems caused by wide-dispersion speakers spraying their sound all over the room instead of being directed at the listener. As a result, in a wide-dispersion speaker, the listener hears the room with all its confused and delayed reflections instead of the superb sound available directly from a planar ESL. Roger won't compromise the quality of the sound by using his wide-dispersion design, so he abandoned it in favor of planar ESLs. The sound from his planar speakers are superior to all others with regard to transient response, 3-dimensional imaging, and frequency response.
Full-range, crossoverless ESLs are widely believed to be the "holy grail" of loudspeakers. In theory, using a single drive to reproduce the entire audio range, without the problems introduced by crossovers, would be ideal. Roger has built many such speakers. But the laws of physics cannot be circumvented. A full-range ESL simply cannot produce deep, powerful bass or have generally high output and full dynamic range.
Roger spent 17 years developing woofer systems that would blend seamlessly with a massless ESL to produce outstanding bass and end the frustrating limitations of full-range ESLs. His well-designed, hybrid systems are far superior to a full-range, crossoverless ESL.
While building and selling full-range ESLs is easier and less costly than a hybrid, Roger won't compromise. Therefore all Sanders speakers are hybrids.
Crossovers are a major limitation in conventional speakers. The passive crossovers typically used are seriously flawed and cannot be used if you want a speaker with the highest possible performance. Electronic crossovers and bi-amplified operation are far superior to passive crossover systems and are absolutely essential for spectacular speaker performance. Therefore, all Sanders' speakers come with electronic crossovers and bi-amplification.
To eliminate the usual customer complaint about having to buy two amplifiers to operate bi-amped speakers, Sanders supplies a Magtech amplifier as part of each Model 10 speaker system. The customer then only has to provide a single amplifier of his choice just as they would for any conventional speaker system.
These amplifiers are not cheap, underpowered, or Class D switching amplifiers. They are multi-hundred watt, Class AB amplifiers that are very expensive, offer the finest in performance, come in beautiful chassis, and will drive the speakers with full dynamic range at realistic, concert hall levels.
When a speaker system is put in a room, it will interact with the room and this will have adverse effects on the sound. Even a "perfect" speaker system will be degraded by the room. It therefore is essential for all speakers to be adjustable to compensate for room effects. The electronic crossovers used in Roger's speaker systems have extensive controls to allow the user to adjust the speaker to compensate for the flaws in his listening room.
This adjustability means that the user can make the speakers sound almost any way they wish. It is no longer necessary to be "stuck" with the particular sound of a room/speaker combination as is the case with conventional speakers. If you don't like what you hear with Sander's electrostatic speakers, you can adjust them so that they sound the way you like.
In summary, Sanders' speakers use the finest technology and design possible.
No compromise is made to either to reduce cost or sacrifice any aspect of speaker performance. The combination of electrostatic mids/highs, transmission line woofers, and fully adjustable electronic crossovers makes it possible finally to have a speaker system that can do it all without compromise.
