As much as one would like to have such a thing as today’s headline, a perfect loudspeaker is a theoretical concept that does not exist in reality.
If there were to be such a beast, what would it look like?
Here’s a short list to get us started:
- Accurately reproduce the full audio spectrum: A perfect loudspeaker would be able to accurately reproduce all frequencies in the audio spectrum, from the lowest bass notes to the highest treble, without emphasizing or suppressing any particular frequency range.
- Have uniform frequency response across all frequencies, meaning that it would produce the same level of output at all frequencies. This would allow the listener to experience music as it was intended to be heard, with a neutral and balanced tonal quality.
- Be distortion-free producing no added harmonic content. The listener would hear only the original signal and not any artificial artifacts.
- Be time-coherent, producing sound that arrives at the listener’s ears at the same time, regardless of the frequency or location of the speaker.
- Be phase-coherent producing sound waves that are in phase with each other, meaning that their crests and troughs are aligned, with no phase cancellations or peaks.
While it is not currently possible to build a perfect loudspeaker, we can get pretty close.
I look forward to showing off what I consider to be about as close as it gets, the aspen series of speakers.
But close enough to absolutely right to put a smile on your face.
