Request A QuoteHarbottle Audio designs and manufactures Cassini Tradition, Cassini Carbon and HYPERSUB subwoofers, combining cutting-edge technology, meticulous craftsmanship, and innovative design to create products that not only exceed industry benchmarks but also elevate the listening experience for audiophiles and home theater enthusiasts alike.
All Cassini Tradition, Cassini Carbon and HYPERSUB products are based on a unique engineering methodology, Low Distortion Low Compression (LDLC). While most manufacturer specifications only extend to small signal efficiency metrics and qualifier-less max SPL figures, Harbottle Audio concentrates on what truly defines real-world capability: reproducing large-signal content at realistic SPLs, without noticeable distortion or compression.
Through rigorous Low Distortion, Low Compression (LDLC) testing at maximum output, Harbottle ensures each Cassini Tradition, Cassini Carbon and HYPERSUB subwoofer delivers consistently clean, dynamic bass, with inaudible distortion and compression. This meticulous validation not only eliminates audible distortion and eliminates compression artifacts—it also sets a new standard for reliability under pressure.
This is more than incremental improvement—it's an overdue solution to the industry's accepted shortcomings. Gone are the bloated, sluggish, or indistinct bass signatures common to many high-output subwoofers. In their place: articulate, controlled, and deeply engaging low-frequency performance, preserving nuance, speed, and clarity even at reference-level playback.
Cassini Tradition, Cassini Carbon and HYPERSUB redefine what's possible, elevating the low-frequency experience from mere sound reproduction to true emotional immersion.
All Cassini Tradition, Cassini Carbon and HYPERSUB products are artisan crafted in Canada. Transducers feature hand-made carbon cones and powerful neodymium magnets cut from US steel. Cabinets utilize void-free plywood with thick shop sawn veneers or laminated carbon fiber. What's more, each subwoofer undergoes over 500 quality control steps ensuring that the performance of every shipped subwoofer is the same as the engineering sample.
