The massive aluminum phase connector of the Dayton Audio Reference RS225 offers a variety of acoustic advantages. Primarily, it reduces mechanical distortions that typically occur at high displacements by minimizing phase anomalies in sound reproduction. This leads to improved sound clarity and a more homogeneous sound radiation. The phase connector helps optimize the temperature of the voice coil, which reduces thermal stress and contributes to a longer lifespan of the speaker. The aluminum construction also provides the advantage of increased stability, positively affecting the dynamic frequency range, especially at low frequencies, where bass notes are reproduced more clearly and powerfully.
The resonance frequency (Fs) is a crucial parameter of the Dayton Audio Reference RS225. For the 4-ohm model, it is 33 Hz, and for the 8-ohm model, it is 28.3 Hz. This frequency indicates the point at which the speaker begins to vibrate spontaneously and operates most efficiently. A low resonance frequency, like that of the RS225, favors deep bass reproduction and ensures that the speaker is capable of delivering authentic and powerful bass notes. The precise tuning of the speaker in the enclosure is essential to optimally utilize this resonance frequency, resulting in clean and accurate sound reproduction, especially in applications requiring low frequencies, such as in home theater or music systems.
