DeVore Fidelity Orangutan O/Bronze Loudspeakers at Vinyl Sound Toronto Canada

The O/Bronze is a two-way floorstanding loudspeaker from DeVore Fidelity (Brooklyn, New York, USA), available at Vinyl Sound in Toronto, Canada. Positioned between the award-winning Orangutan O/96 and the flagship O/Reference, the O/Bronze brings direct descendant technology from the O/Reference into a refined, room-friendly cabinet. Both drivers feature cast and machined bronze chassis inherited from the O/Reference, paired with bronze port tubes that float mechanically free of the cabinet to minimize vibration coloration. With a 96 dB/W/m sensitivity, a 10-ohm impedance, and a frequency response of 26Hz to 25kHz, the O/Bronze pairs naturally with virtually any amplifier, from low-power single-ended triode designs to high-powered solid-state. Solid-hardwood stands and grills are included with every pair, and every cabinet is handbuilt at the DeVore Fidelity workshop at the Brooklyn Navy Yard.

O/Reference Technology in a Refined Floorstander

The O/Bronze tweeter is the identical 1-inch silk dome unit used in the O/Reference flagship, loaded by a cast and machined bronze horn and driven by a motor with a large rare-earth magnet and an underhung voice-coil for improved linearity at lower treble frequencies. The 10-inch paper-cone woofer is purpose-built for the O/Bronze, using the same German paper cone found in the O/96 but rebuilt around a cast bronze chassis, a copper Faraday ring at each end of the magnetic gap for improved inductive linearity, a copper ring mounted directly to the machined bronze phase plug that acts as a heat sink to reduce thermal compression, and bronze port tubes at the rear that are mechanically decoupled from the cabinet. The result is a driver that shares the same chassis architecture as the O/Reference while delivering a new level of linearity, dynamic coherence, and low-frequency authority that clearly surpasses the O/96 in bass body, weight, detail, and perceived dynamic speed.

Bronze Chassis: Materials, Craftsmanship, and Acoustics

The bronze driver chassis and horn bodies used in the O/Bronze are the same components found in the O/Reference, cast by Tektonics Design Group and machined to final tolerances before being assembled into finished drivers. Bronze is chosen over the zinc alloy chassis used in the O/96 for its greater structural stability and meaningfully lower resonance, which reduces coloration in the critical midrange and upper bass. The solid machined bronze port tubes extend through the rear of the cabinet and are isolated from the enclosure walls so that cabinet vibrations cannot be transmitted back into the airflow. The result is a speaker that looks and sounds like a direct expression of O/Reference thinking, built into a cabinet that shares the same external dimensions as the O/96.

Key Features

• O/Reference Tweeter: The identical 1-inch silk dome tweeter from the flagship O/Reference is used in the O/Bronze, mounted in the same cast and machined bronze horn with a large rare-earth magnet and underhung voice-coil for extended high-frequency linearity.
• New 10-Inch Bronze-Chassis Woofer: The purpose-built 10-inch paper-cone woofer uses a cast bronze chassis, dual copper Faraday rings for improved magnetic linearity, a machined bronze phase plug, and a copper heat-sink ring to reduce thermal compression.
• Vibration-Decoupled Bronze Port Tubes: Solid machined bronze rear port tubes are mechanically isolated from the cabinet walls, preventing cabinet vibration from coloring the bass output.
• 96 dB/W/m Sensitivity: The O/Bronze is highly sensitive and works equally well with low-power tube amplifiers, including 300B single-ended triode designs, and with high-powered solid-state amplifiers.
• 10-Ohm Impedance: An amp-friendly 10-ohm nominal impedance presents a stable, easy load to virtually any amplifier topology.
• 26Hz to 25kHz Frequency Response: Full-range, two-way performance from the lowest bass through the upper treble, covering the complete musical spectrum.
• Solid-Hardwood Stands Included: Each pair ships with purpose-designed solid-hardwood stands that position the drivers at the correct listening height and contribute to the overall mechanical stability of the system.
• Grills Included: Magnetically attached grills are included with each pair for a clean visual presentation when preferred.
• Same Cabinet Dimensions as the O/96: The O/Bronze occupies the same room footprint as the award-winning O/96, making it a natural upgrade path for existing O/96 owners or anyone who values a compact, room-friendly floorstander.
• Handbuilt in Brooklyn, New York: Every pair is assembled by hand at the DeVore Fidelity workshop at the Brooklyn Navy Yard, New York, USA.

Press and Critical Recognition

• Michael Lavorgna, Twittering Machines (September 2025): "The O/Bronze are among the most engrossing loudspeakers I've had the great pleasure of living with, placing music intimately close, me inside of it, or it inside of me."

Frequently Asked Questions

What is the DeVore Fidelity Orangutan O/Bronze?

The DeVore Fidelity Orangutan O/Bronze is a two-way floorstanding loudspeaker handbuilt in Brooklyn, New York, positioned between the award-winning O/96 and the flagship O/Reference in the Orangutan Series. It uses a 1-inch silk dome tweeter and a 10-inch paper-cone woofer, both mounted in cast and machined bronze chassis inherited directly from the O/Reference. The O/Bronze delivers a 96 dB/W/m sensitivity, a 10-ohm impedance, and a 26Hz to 25kHz frequency response, and ships with solid-hardwood stands and grills included.

How does the O/Bronze compare to the DeVore Fidelity O/96?

The O/Bronze and O/96 share the same external cabinet dimensions and the same German paper cone in the woofer, but the O/Bronze goes significantly further in driver engineering. Where the O/96 uses a zinc alloy woofer chassis, the O/Bronze uses a cast bronze chassis with dual copper Faraday rings, a machined bronze phase plug, and a copper heat-sink ring to reduce thermal compression. The O/Bronze also uses the O/Reference tweeter rather than the O/96's tweeter. Reviewers have consistently noted that the O/Bronze delivers greater bass body and weight, higher dynamic energy, and a richer, more refined overall presentation than the O/96, which it directly supersedes in the Orangutan lineup.

How does the O/Bronze compare to the Harbeth M30.2 XD or the Spendor D7.2?

The DeVore Fidelity O/Bronze, the Harbeth M30.2 XD, and the Spendor D7.2 all occupy the upper tier of music-focused, tonally refined loudspeaker design, but they take very different approaches. The O/Bronze at 96 dB/W/m is dramatically more sensitive than either the Harbeth M30.2 XD or the Spendor D7.2, both of which measure in the mid-to-high 80s and require substantially more amplifier power. The O/Bronze also uses cast bronze driver chassis and horn-loaded tweeter geometry that is not found in either British alternative. For listeners who pair speakers with tube amplifiers or value a warmer, higher-efficiency sound, the O/Bronze offers a meaningfully different proposition.

Can the O/Bronze be driven by a low-power tube amplifier?

Yes, the O/Bronze is exceptionally well suited to low-power tube amplifiers. Its 96 dB/W/m sensitivity and 10-ohm impedance make it one of the most amplifier-friendly floorstanders available at its level. During its extended review period at Twittering Machines, the O/Bronze was paired with multiple 300B-based single-ended triode integrated amplifiers and performed to a very high standard with each. Even amplifiers producing fewer than ten watts can drive the O/Bronze to realistic listening levels without strain.

What is the benefit of using a cast bronze driver chassis?

A cast bronze driver chassis is significantly more rigid and internally damped than the zinc alloy chassis used in more conventional speaker designs, including the O/96. Greater rigidity means the basket does not flex under high excursion, which keeps the voice-coil centered in the magnetic gap and reduces intermodulation distortion. The higher internal damping of bronze also absorbs resonances that would otherwise color the output of the driver through the midrange. Bronze port tubes serve the same purpose: by decoupling them from the cabinet walls, vibration from the enclosure cannot travel back into the bass airflow and add coloration to the low frequencies.
