Introduction to Speaker Reviews
Speakers, or Loudspeakers, are a most influential component of an audio system. Regardless of advances in digital signal processing and amplification, speakers will always be an inherently analogue, mechanical component. They have the potential to last not years but decades and as such a purchase decision carries more weight than that of other AV components. There is a tremendous array of speaker designs, including acoustic suspension, ported, band pass, transmission line to name but the most common. There is also diverse transducer technology. The vast majority of speakers will include a high frequency driver, called a tweeter, coupled with one or more low frequency drivers, called woofers. On more advanced models a mid-range driver may also be used. The signal sent to the speakers is divided by the crossover, a collection of electrical components which separates the high, middle, and low frequencies and sends them to the respective transducer.
Speakers may be designed for general use, or for more specific implementation such as a particular channel in a multi-channel audio system, or a specific frequency range such as a dedicated bass module, known as a sub-woofer.
Our focus when evaluating speakers is on accuracy, both in terms of frequency response and transient response. We use objective measurements when possible, including quasi-anechoic measurements and impedance sweeps, coupling that with subjective “real world” auditioning.
