Dipolar Speakers and Your Room, Solid Footing

on the floor or solid surface, it can shake as it produces sound and, consequently, the sound can be compro- mised. If your speaker is sitting on the carpet and only foot gliders are used, the bass can be ill defined and even boomy. The use of spikes is recommended to insure secured footing for your speakers. (See ‘Solid Footing’ for spike information and installation instructions).

Dipolar Speakers and Your Room

MartinLogan electrostatic loudspeakers are known as dipolar radiators. This means that they produce sound from both their fronts and their backs. Consequently, musical infor- mation is reflected by the wall behind them and may arrive, either in or out of step, with the information produced by the front of the speaker.

In a typical speaker system the low frequencies can either be enhanced or nulled by the position from the front wall. Listening to the difference of the bass response as a result of the changes in distance from the front wall will allow you to get the best combination of depth of bass and tonal balance.

Now that you know about reflective surfaces and resonant objects, you can see how the midrange and high frequencies can be affected. The timing of the initial wave as it radiates to your ears, and then the reflected information as it arrives at your ears later in time, can result in confusion of the precious timing information that carries the clues to imaging. Consequently the result is blurred imaging and excessive brightness. Soft walls, curtains, wall hangings, or sound dampeners (your dealer can give you good information here) can be effective if these negative conditions occur.

After living and experimenting with your Odysseys, you will then want to implement the enclosed 3/8" x 16 thread special version ETC (Energy Transfer Coupler) Spikes (See Figure 6). With the use of these spikes, the Odyssey will become more firmly planted on the floor and, conse- quently, bass will tighten and imaging will become more coherent and detailed. It is best not to implement the spikes, however, until you are secure in the positioning, as the spikes can damage the floor if the speaker is moved.

MartinLogan ETC spikes are also available with a common 1/4" x 20 thread insert that may be used on your other audio equipment (racks, speakers, etc.), which are avail- able from your local MartinLogan dealer or on our website at www.martinlogan.com.

Spike Installation Instructions:

1.Carefully lay your speaker on its side to gain access to the bottom.

2.Remove existing feet or spikes. Thread new spikes into holes and visually adjust to an equal height.

3.Tighten jam nut snugly by hand. Do not over tighten the nut.

4.Right the speaker.

Caution: Make sure your hands and any cabling are clear of the spikes. Do not slide speaker as spikes are sharp and can damage your floor or carpet.

5.Adjust to level by rotating spikes. Tighten the jam nut securely when satisfied that speaker is level.

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.
