MARTINLOGAN EXCLUSIVES

Full Range Operation

Another significant advantage of MartinLogan’s exclusive transducer technology reveals itself when you look at exam- ples of other loudspeaker products on the market today.

The Source uses no crossover networks above 470 Hz because they are not needed. The Source consists of a single, seamless electrostatic membrane reproducing all frequencies above 470 Hz simultaneously. How is this pos- sible?

First we must understand that music is not composed of separate high, mid and low frequency pieces. In fact, music is comprised of a single complex waveform with all frequencies interacting simultaneously.

The electrostatic transducer of the Source essentially acts as an exact opposite of the microphones used to record the original event. A microphone, which is a single work- ing element, transforms acoustic energy into an electrical signal that can be amplified or preserved by some type of storage media. The Source’s electrostatic transducer transforms electrical energy from your amplifier back into acoustical energy.

Due to the limitations of electromagnetic drivers, no single unit can reproduce the full range of frequencies. Instead,

Figure 16. This diagram illustrates how a convention- al speaker system must use multiple crossover networks that have negative effects on the musical performance.

these drivers must be designed to operate within a nar- row, fixed bandwidth of the frequency range, and then combined electrically so that the sum of the parts equals the total signal. While nice in theory, we must deal with real-world conditions.

In order to use multiple drivers, a crossover network is enlisted to attempt a division of the complex musical signal into the separate pieces (usually highs, mids, and lows) that each specific driver was designed to handle. Unfortunately, due to the phase relationships that occur within all crossover networks and during the acoustical recombination process, nonlinearities and severe degra- dation of the music signal take place in the ear’s most critical zone (see figure 16).

The Source’s electrostatic transducer can single-handedly reproduce all frequencies above 470 Hz simultaneously. You have in one transducer the ability to handle in elegant simplicity the critical frequencies above 470 Hz.

The crossover phase aberrations that are associated with traditional tweeter, midrange, and woofer systems are eliminated. The result is a dramatic improvement in imag- ing and staging performance due to the minutely accurate phase relationship of the full-range panel wave launch.

Source Speakers specifications

The MartinLogan Source Speakers are a testament to the brand's dedication to high-fidelity sound and innovative design. Renowned for their stunning performance and elegant aesthetics, these speakers cater to audiophiles and casual listeners alike, seamlessly blending into any home audio setup.

At the heart of the Source Speakers is their unique hybrid electrostatic technology. This innovative approach combines the purity of an electrostatic panel with the dynamic bass response of a traditional woofer. The electrostatic panel, known for its ability to recreate sound with exceptional clarity and precision, is complemented by a high-output dynamic woofer. This synergy allows the Source Speakers to deliver a full range of frequencies, from the detailed highs to the robust lows, ensuring an immersive listening experience.

One of their standout features is the Folded Motion tweeter, which utilizes a unique diaphragm that moves in a pleated fashion. This design enables the tweeter to produce greater output and higher efficiency while minimizing distortion. As a result, the Source Speakers are capable of delivering crisp, clear highs that can fill even the largest rooms.

Additionally, the Source Speakers boast a stylish and contemporary design. The elegant cabinetry is crafted from high-quality materials and finished in a range of attractive veneers, allowing them to blend harmoniously with any home decor. The speakers are also relatively compact, making them suitable for a variety of spaces, from dedicated listening rooms to casual home theater setups.

Connectivity is another strong suit of the Source Speakers, with options that include high-quality binding posts for straightforward integration with various amplifiers and audio systems. This versatility ensures that users can easily incorporate these speakers into their existing setups without hassle.

In terms of performance, the Source Speakers excel in creating a soundstage that is both wide and deep. Their ability to produce accurate spatial imaging allows listeners to feel as if they are in the center of the performance. This makes them ideal not only for music lovers but also for movie enthusiasts who crave that cinematic audio experience.

Overall, the MartinLogan Source Speakers represent a perfect amalgamation of cutting-edge technology, stylish design, and outstanding audio performance. Whether for music playback or home theater use, they offer an unparalleled listening experience that will satisfy even the most discerning audiophiles.
