Hartley - Compact Reference
Monitor

Design & Materials

Compact Reference Monitor
Specifications
High Performance Driver Design
The Compact Reference Monitors use a polypropylene driver with an exceptionally large voice coil and magnet fabricated in-house to Hartley precision specs. The design allows for greater linearity, resulting in exceptional dynamic range and clarity, as well as extended low end response with minimal distortion.
Tuned Port
2” x 2.5” front-firing port tuned at
45 Hz.
Cabinet Shape
The cabinet is designed to minimize unwanted reflections. While square boxes amplify energy along the edges, our unique shape embraces that energy. Instead of trying to eliminate it through dampening, the design uses it to amplify sound, much like a reverse horn. The waffled edges at the back of the speaker help guide the sound out smoothly, like turbulence at the end of an aircraft wing. This keeps the sound clean and clear, without those unwanted reflections.
Cabinet Design
Cabinet is made from high-quality, solid 3 ply bamboo, cured and CNC fabricated in our woodshop. Bamboo is selected for its density, and resonance control which lends a natural harmonic contribution to the speaker sound.
Interior of Cabinet
A blend of different density sheep and hemp wool, sourced locally, is used for sound dampening within the cabinet.
Audio Engineered Design
The Reference speakers are now
on short stands instead of being
floor-standing. This in combination
with the changed orientation of the front-firing ports and tweeter in one circle tightens up and focuses the sound better making it faster and more detailed.
Acoustically treated sound absorber.

Stands

Artfully designed, cleverly engineered. The Reference (26”) Stands are engineered and crafted in our wood shop. Although designed for the Compact Reference and optimal sound for seatedpositioning , they are an excellent choice for any monitor. Made with solid 3 ply bamboo which imparts a natural harmonic that is pleasing and will make your system and room sound better. The lateral and horizontal supports provide extreme strength and rigidity . The composition and design allow natural suppression of resonances and unwanted energy transfer between floor and monitors. Each stand has adjustable spikes with brass bracing that ensures ease of installation. The finishes are hand rubbed and meticulously applied. Stands are factory flat-packed for safe and eco-friendly shipping and offer ease of assembly.
Crafted with high-quality, solid 3-ply bamboo, cured and precision CNC fabrication in-house. The lateral bracing to ensures rigidity, stability and resistance to warping. Bamboo is selected for its density, and resonance control which lends a natural harmonic contribution to the speaker sound. The adjustable bronze spikes also provide stability and manage vibration transfer.
The stands come factory flat-packed for safe and eco-friendly shipping and are easily assembled.
Finished with a hand rubbed oil application in Natural/Black and Black. Graphite and Distressed are optional finishes.

Revived Hartley Loudspeaker

Re-imagined by Tri-Art Audio

Hartley Loudspeakers are renown for both their quality and sound. The Compact Reference Monitors by Tri-Art Audio share the same genuine drivers, crossover and internal volume as the original Hartley compact in a re-imagined contemporary design. The new design for the monitor has a reconfigured orientation of the ports and tweeter for a tightened sound. This in combination with the modern design elements of the cabinet takes the Compact Reference from a ‘70s monitor sound to a more modern, high-resolution, fast, and detailed presentation.
