What Symposium Acoustics does
Symposium Acoustics (legal entity Symposium USA, Inc.) is a privately-held, founder-owned US manufacturer of high-end audio vibration control products and loudspeakers, founded in 1992 by Peter Bizlewicz and operated from a New Jersey facility where the majority of parts and materials are made domestically. The company's core technology is mechanical energy drainage through constrained-layer damping (symmetrical aluminum/foam sandwich platforms), patented ball-bearing lateral isolation (the Rollerblock system, US Patent #5,804,776), and stepped mechanical impedance coupling. The product portfolio spans equipment support platforms (Super Plus, Quantum Signature, Segue, Segue ISO, Super Segue ISO), isolation footers (Rollerblock Series 2+, Rollerblock Jr., HDSE), complementary couplers and pads (Fat Padz, Ultra Padz, Point Pods, Precision Couplers, SuperCouplers), the modular Isis equipment rack with EMI/RFI Faraday shielding, the Osiris rack with patented magnetic bias bearing stabilization, model-specific turntable damping kits, and the Panorama four-way hybrid loudspeaker combining proprietary planar-magnetic and ribbon drivers with transmission line woofers.
Revenue is generated entirely through one-time hardware sales, distributed via a global network of factory-authorized dealers complemented by direct phone/email sales for premium lines (Panorama, Quantum Signature, Isis rack) where pricing is provided on inquiry. Customer segments are led by individual high-end audiophiles seeking vibration control for premium audio/video systems, with secondary demand from recording studios and home theater enthusiasts. Marketing is anchored by an extensive content-rich website, earned media through publications such as Stereophile, The Absolute Sound, and Soundstage!, and participation in major audio trade shows (CES, Rocky Mountain Audio Fest, Stereophile shows). All products are positioned at the premium tier of the niche, with documented engineering differentiators including Grade 10 tungsten carbide bearings at 10 parts per million tolerance and proprietary LDSS (Linear Displacement Suspension System) conical-spring isolation.
