DESCRIPTION

The Lyra embodies an unsurpassed combination of refinement and authority, housed in the most technically advanced loudspeaker enclosure ever produced.

Three years of development, 30 years in the making
The culmination of three decades of loudspeaker design and manufacture, the new Lyra is the quintessential expression of Rockport Technologies' craftsmanship. The Lyra embodies an unsurpassed combination of refinement and authority, housed in the most technically advanced loudspeaker enclosure ever produced.

Extraordinarily complex, beautifully simple
An exquisite marriage of elegant industrial design and optimized acoustic proportion, the entire enclosure for the Lyra is comprised of just two components, the outer housing and the inner housing/baffle. Each of these components is formed as a single, continuous aluminum casting which nest together to create the inner and outer shell of the composite enclosure. All of the bracing, stiffening fins, drive unit recesses, and interior volumes are an integral part of the inner housing/baffle casting, as is the series of elliptical section stiffening ribs in the outer housing.

Call in and book an appointment to get a focused demonstration of all our products.

Some of the finest products are built in America & Europe, combined with the finest service and know-how, and expert setup from Electrical power to the finest Audio stands, electronics speakers turntables, and streaming. We stock, install, and configure Roon and MQA.

A form that truly follows function
After the incredibly complex casting process, the entire visible exterior profile of both the inner and outer housings are machined on a five-axis CNC, as are all of the surfaces for mounting the drive units and other components. Because of our fabrication process, Lyra’s form is not constrained by the limitations of flat panels, sheet stock, or extrusion manufacturing methods. Therefore, the enclosure can truly be optimized for correct drive unit placement, reduction of internal standing wave modes, and minimum edge diffraction anomalies, ensuring a clean wave launch for maximum coherency.

Extreme damping meets extreme stiffness – Rockport introduces the DAMSTIF™ enclosure
When nested together, the series of interleaving features of the Lyra’s inner and outer housing form a labyrinth of channels that are filled with over 150 pounds of our custom-formulated, high hysteresis, high mass (115 pounds per cubic foot) damping compound which, when cured, intimately bonds the inner and outer housing together to form a single, massively stiff, highly damped structure. Due to the specific 3-D geometry of the interleaving features on both inner and outer housing, any microscopic deflection of the enclosure in any axis creates shear in the damping core material, effectively obliterating any resonant signature. This fundamental absence of enclosure-induced noise has a profound effect on Lyra’s presentation, yielding the lowest noise floor of any production loudspeaker enclosure. The Lyra’s DAMSTIF™ enclosure is unique in that it has no joinery and no fasteners, and exhibits all of the benefits of true monocoque construction, while simultaneously achieving maximum damping, stiffness, and mass.

Uniquely driven
The Lyra utilizes our latest generation midrange units featuring Rockport’s state-of-the-art, variable section thickness, carbon fiber sandwich composite cones matched to our enormously powerful, ultra-low distortion motor systems, with a usable bandwidth of nearly 6 octaves, and distortion figures lower than some amplifiers (-60 dB!)

The Lyra is configured as a 3 ½ way, where both midrange drivers are working in unison at the bottom end of their range. As frequency increases, the dedicated low-frequency midrange begins its roll-off at approximately 500 Hz, while the wideband midrange continues up in frequency to meet our waveguide-mounted, beryllium tweeter. By effectively doubling the midrange drive surface area (equal to an 8” woofer) in the lower midrange, and then transitioning to a single 6” unit for true point source coherency, the Lyra delivers an unrivaled combination of midrange authority, presence, and purity.

The Lyra’s high frequencies are handled by our custom, waveguide-mounted beryllium tweeter. The waveguide improves the acoustic impedance match of the tweeter at the low end of its range, and allows for lower distortion and greater dynamic expression, as well as improved dispersion characteristics at the midrange/tweeter crossover point. The waveguide is precision diamond-machined and then anodized, rendering a beautiful 3-D luster, and providing an ideal mounting surface for the tweeter itself.

It doesn’t mean a thing if it ain’t got that swing
The extreme lengths that we’ve undertaken to design and manufacture the Lyra would be meaningless if it didn’t fulfill its singular purpose; to present recorded music with such exceptional realism that the listener is essentially transported back to the original musical event.

Simply put, the Lyra offers the highest resolution and lowest noise floor obtainable from a dynamic driver loudspeaker, combined with unsurpassed harmonic integrity and an effortless dynamic presentation. The solidity of its presentation, its singular voice with which it speaks, and its ability to communicate the artists’ very intent will make the Lyra a welcome final purchase for many well-traveled music enthusiasts.
