The Dolmens
The Dolmens seem to be more sculptural art than they are speakers in form, resembling cosmic comets, or perhaps geodesic rock creatures come to life and standing ready to sing there sweet melodies. Yet the enclosures shape is designed to prevent colouration or distortion of the original source material meaning you can have exquisite art and precision loudspeakers in one form.
The walls of the enclosure are a composite construction consisting of an outer layer of your choice of stone, followed by a heavily damping layer of visco-elastic bitumen sandwiched by another internal layer of stone followed by a layer of further damping polyurethane foam, sheep wool and finally Mundorf® Twaron Unicorn Tail wadding.
The encased bitumen layer absorbs vibrations in both surrounding layers of stone preventing speaker enclosure colouration of the drivers output as the wall resonances are effectively damped.
The level of damping produced by this composite construction surpasses that of even the highest quality speakers of our competitors. This is achieved through the combination of the extreme rigidity and mass of the stone layers and the huge damping abilities of the bitumen and foam layers.
The Enclosure volume has a shape designed to funnel the internally radiated sound to its rear tip where it is dispersed by the Mundorf® Twaron Unicorn Tail wadding and pure sheep wool. The Twaron fibres run in a fine layer above the sheep wool from the front to the back inner point, further focusing the sound along their length to the dispersing back point of the enclosure. There are no internal parallel surfaces to prevent standing waves.
By utilising the MANGER® sound transducer the dolmens are able to achieve an incredible 80Hz to 40,000Hz frequency response with a blisteringly fast 13µs rise time. The active surface of the MANGER® sound transducers flexible diaphragm becomes smaller as the frequency increases so that the effective surface is always kept small in comparison to the wavelength to be radiated.
Using a single point sound source for all frequencies above the subwoofers cut-off frequency and especially the frequencies of the human voice gives our speakers a precise sound with none of the cross-over and timing issues usually borne by multi driver systems.
