Dispersion Interactions

Controlled Horizontal Dispersion

Your Source’s launch a 30 degree horizontal dispersion pat- tern. This horizontal dispersion field gives a choice of good seats for the performance while minimizing interactions with side walls (see figure 7). Make sure both speakers stand exactly at the same vertical angle, otherwise the image can be skewed or poorly defined. The wave launch of both speakers is extremely accurate in both the time and spectral domain. Consequently, small refined adjustments can result in noticeable sonic improvements.

Controlled Vertical Dispersion

As you can see from the illustrations, your Source speak- ers project a controlled dispersion pattern (see figure 8). Each Source is a 28 inch line source beginning 22 inches above the base. This vertical dispersion profile minimizes interactions with the floor and the ceiling.

Figure 7– 8. As can be seen here, point source concepts invite a great deal of room interaction. While delivering good frequency response to a large listening audience, imag- ing is consequently confused and blurred.

Figure 9–10.Even though they suffer from “venetian blind” effect, angled multiple panel speakers can deliver good imaging, but only to specific spots in the listening area.

Figure 11–12.A controlled 30 degree cylin- drical wave-front, a MartinLogan exclusive, offers optimal sound distribution with minimal room interaction. The result is solid imaging with a wide listening area.

Three Major Types of Dispersion

It is a known fact that as the sound wave becomes pro- gressively smaller than the transducer producing it, the dispersion of that wave becomes more and more narrow, or directional. This fact occurs as long as the transducer is a flat surface. Large flat panel speakers exhibit venetian blind effects due to this phenomenon. This is one reason why many manufacturers opt for small drivers (i.e. tweeters and midrange) to approximate what is known as a point source wave launch.

Historically, most attempts to achieve smooth dispersion from large flat panel transducers resulted in trade-offs. After exhaustive testing of many different methods, we conceived an elegantly simple, yet intensely hand craft- ed process. By curving the radiating surface, we create the effect of a horizontal arc. This allows the engineers at MartinLogan to control the high frequency dispersion pat- tern of our transducers.

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.
