Accoustic point source
Improves the spacial sound pattern of porcelain ball speakers.
An accoustic point source is a point-shaped sound source, which means that all signals originate from one single punctiform source.
This might just be a physical model and it doesn’t exactly work like this in real life, but a broadband speaker built into a spherical casing is the prerequisite for an almost perfect accoustic point source.
2 way speaker
A broadband speaker transmits the entire frequency spectrum from one single chassis; a one-way speaker thus covers high, middle and low frequencies.
The advantage is clear: all sound waves are constantly in equal distance to the listener. An accoustic point source improves spacial sound massively, since the signals don’t reach the listener’s ears from differently positioned drivers. Contrarily, the soundwaves all arrive at the same time. Group delay differences ind interferences are minimised.
Other two-way speaker concepts, such as the coaxal speaker, try to build in the different sound sources as close together as possible. But this does not have the same effect as a broadband speaker which is also an accoustic point source.
Our membranes are small and swift, 3 inch or 4 inch drivers. However – or rather, therefore – they produce brilliant sound: since they are so small, they transfer less air drag – and sound is basically air – and are consequently faster and more exact.
This is their contribution to creating clean, exact sound.
