Sound is always a priority
In a traditional loudspeaker, the diaphragm acts as a “rigid piston” at low frequencies, but turns into a multimodal object when approaching its so called “breakup region”.
In a BMR, there is no “break-up region”. Instead, a limited number
(usually 2 – 4) of evenly spread modes are carefully positioned within the frequency band. The modal, bending-wave operation starts in the frequency range where the piston-like operation of the panel would otherwise cause the driver to beam.
Thanks to the bending wave operation, the drive unit demonstrates wide dispersion even at high frequencies. Acoustically, the behaviour of a BMR approximates to the ideal “point source”.
In most situations, typical high end speakers deliver the best sound only in a very small and limited space, usually on the center axis and only in certain distance. This effect is called sweet spot. Thanks to its unique wide and even dispersion technology, Gravelli Bespoke Audio has much wider Sweet Spot, allowing up to 5 people to sit and listen within.
