Full Range Operation

The most significant advantage of MartinLogan’s exclusive transducer technology reveals itself when you look at examples of other loudspeaker products on the market today.

The Odyssey uses no crossover networks above 250 Hz because they are not needed. The Odyssey consists of a single, seamless electrostatic membrane reproducing fre- quencies above 250Hz simultaneously. How’s this possible?

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

Due to the limitations of electromagnetic drivers, no single unit can reproduce the full range of frequencies. Instead, these drivers must be designed to operate within

narrow, 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 degradation of the music signal take place in the ear’s most critical zone (See Figure 17).

The Odyssey’s electrostatic transducer can single-handedly reproduce all frequencies above 250 Hz simultaneously. You have in one transducer the ability to handle in elegant simplicity the critical frequencies above 250 Hz.

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

Odyssey specifications

The MartinLogan Odyssey is a distinguished loudspeaker that showcases the brand's commitment to innovation, craftsmanship, and exceptional audio performance. This electrostatic speaker is designed for audiophiles who desire an immersive listening experience, blending advanced technology with luxurious aesthetics.

At the heart of the Odyssey is MartinLogan's renowned electrostatic technology, which utilizes a thin, electrically charged diaphragm suspended between two perforated metal stators. This design allows for extremely low distortion and a wide frequency response. The result is clear, detailed sound reproduction that captures the nuances of both music and film audio, making it a perfect choice for critical listening environments.

One of the standout features of the Odyssey is its unique design that incorporates the company's latest advancements in transducer technology. The speaker boasts a large, full-range electrostatic panel, which provides an expansive soundstage and extraordinary imaging. This panel is complemented by a high-performance, low-frequency driver that seamlessly integrates with the electrostatic element, ensuring a well-rounded and balanced sound across the auditory spectrum.

The cabinet design of the Odyssey is also noteworthy. Crafted from high-quality materials, the enclosure is engineered to minimize resonance while providing a visually appealing appearance. The sleek, contemporary design fits elegantly into a variety of interior settings, making the speakers a stylish addition to any audio setup.

Another significant feature of the MartinLogan Odyssey is its precise, adjustable crossover network. This network manages the transition between the electrostatic panel and the woofer, ensuring smooth integration and coherence across all frequencies. Such precision in engineering allows discerning listeners to enjoy their favorite recordings with impeccable clarity and detail.

Additionally, the Odyssey is designed for versatility in placement. The speaker is equipped with various adjustment options for height and tilt, allowing users to optimize sound dispersion and field. This adaptability makes it suitable for both dedicated listening rooms and home theaters.

In summary, the MartinLogan Odyssey exemplifies what can be achieved with state-of-the-art electrostatic technology combined with thoughtful design. With its focus on audio fidelity, impressive build quality, and aesthetic elegance, the Odyssey stands as a titan among high-end loudspeakers, appealing to both audiophiles and casual listeners alike.
