The Quest for the Perfect Audio Speaker System: Key Considerations
Introduction
Choosing the right audio speaker system is not a trivial task. Whether in a professional setting or for personal enjoyment, the quality of sound can significantly enhance or detract from the overall experience. From vintage Klipsch speakers to modern horn-loaded models, each has its unique strengths and weaknesses. In this article, we explore the factors that contribute to an excellent audio speaker system and why it is so important that it sounds 'right'.
The Importance of Accurate Sound
For many audio enthusiasts, the quest for the perfect speaker system is driven by the desire to experience sound that is as close to the performance of live orchestral music as possible.
Live orchestral music is a benchmark for high-quality sound, characterized by its massive, clean, clear nature with thrilling transients that can evoke emotions and bring people to tears. Achieving this level of sound quality in a domestic or professional setting is the ultimate goal of many audio professionals.
Key Factors in Choosing the Right Speaker System
1. Modulation Distortion
Modulation distortion, a type of distortion that occurs when harmonically unrelated side tones are created, can significantly affect the sound. This distortion is particularly problematic in speakers because it can create an unbalanced sound that hampers the overall listening experience. While subwoofers tend to produce less modulation distortion due to their wide excursion, fully horn-loaded speakers are praised for their lower distortion levels.
2. Horn Loaded Speakers
Horn-loaded speakers are highly favored due to their high sensitivity, low distortion, and excellent transient response. These characteristics make them stand out in terms of sound quality. For example, well-designed three-way horn loudspeakers can provide up to 10 dB higher sound pressure level (SPL) at much lower sound distortion levels compared to conventional speakers.
3. Frequency Response and Sensitivity
A speaker system that can deliver a wide range of frequencies with high sensitivity is crucial. Sensitivity, or efficiency, ensures that the necessary sound pressure level can be achieved with a relatively low power output, making the system more efficient and cost-effective. Sensitivity is typically measured in decibels (dB) per watt per meter (1W/1m).
4. Imaging and Dynamics
Imaging refers to the ability of a speaker system to create a three-dimensional soundfield, giving the impression that instruments and voices are located in specific positions within the room. Dynamics, which refer to the ability to reproduce subtle and exaggerated sound levels, are also essential for a realistic and engaging listening experience.
Examples of Excellent Speaker Systems
1. Klipsch LaScala With Sony Sub
For those who appreciate vintage technology, the Klipsch LaScala paired with a small Sony-powered subwoofer offers a balanced sound, particularly for modern music. The LaScala seems weak in the low octave, but the subwoofer fills in the missing frequencies to create a more complete sound.
2. Meyers Stacks and SmithProAudio Systems
Professional audio enthusiasts often opt for Meyers stacks or line arrays, which are high-quality but expensive. For budget-conscious clients, systems like SmithProAudio 1203 passive 3-ways on top of an 18-inch passive subwoofer are a popular choice. These systems are usually crossed over at 100 Hz.
3. Mackie, QSC, and JBL Speakers
In smaller venues, powered Mackie, QSC, or JBL speakers are commonly used, often with at least one powered subwoofer. These systems provide a good balance of performance and affordability.
Conclusion
The quest for the perfect audio speaker system is a continuous journey, driven by the pursuit of audio quality and the desire to recreate live experiences in a home or professional setting. By focusing on key factors such as modulation distortion, horn loading, and sensitivity, one can find a speaker system that delivers an exceptional listening experience.
