All loudspeaker models are made-to-order. Before fabrication begins we will discuss product customization options with you. This includes choice of granite for enclosure, presence (or absence) of logo, as well as optional higher-cost film capacitors. Production is limited to a handful of systems per year. We provide free delivery and setup within San Diego, Orange, Los Angeles and Ventura Counties.

Depending on availability, we offer free in-home demos in San Diego and Orange County. A security deposit is required.

We offer limited-production, high-end loudspeaker designs. Enclosures are fabricated by a master craftsman from raw slabs of solid granite. Manufacture and assembly is done at our facility in Southern California. Electro-acoustic design is carried out using proprietary software that includes our own engines for diffraction analysis, transducer motor/suspension modeling and sound radiation analysis. We carry out research in theoretical and applied acoustics, and leverage this research in our design methodology.

For the construction of a small bookshelf loudspeaker, panels made from MDF or Baltic Birch plywood may exhibit acceptably low panel vibration and transmitted SPL -- even without internal bracing. However, as the size of the loudspeaker enclosure increases, transmitted SPL due to panel vibration becomes an unavoidable issue. For large enclosures typical of floorstanding loudspeakers, panel resonances are readily visible as narrow peaks in the measured impedance and are thus potentially audible. For traditional enclosure materials it is necessary to add internal-wall bracing (i.e., cross-members) and/or damping material (i.e., fiberglass or fiberfill) to mitigate unwanted vibration. Unfortunately, for very large floorstanding loudspeakers, adding excessive bracing can lead to unpredictable behaviour due to air-flow modification. Similarly, adding excessive damping material creates internal viscous losses that reduce low-frequency output. This loss of output is an effect that is well-known and simple to measure. We believe granite represents an ideal solution to the problem of panel resonance control. With granite, one can achieve a completely inert, lossless enclosure with exceptional low-frequency output and uncolored sound reproduction.
