Avalon Acoustics Precision Monitor 4 is a full range reference monitor designed specifically for superlative tonal and spatial accuracy. Recovery of fine low-level detail, maximum possible resolution, transient accuracy, and exceptional dynamic contrast were our specific design goals. Accurate tracing of all waveform parameters, without exaggeration or artifact is the hallmark of the Precision Monitor 4, a transparent window into the heart of recorded music.

PM4 internal cabinet construction is uniquely designed with a combination of sealed chambers and multiple labyrinth pathways. Developed over our 30 years of experience into resonance elimination and utilization, PM4 employs both a multi-layered constrained damping platform for the main baffle, along with carefully tuned cavity resonances for eigenmode reinforcement and control. In simple terms, the cabinet functions like a finely made violin or guitar, stiff and non-resonant at the point of sound propagation, with tuned in-phase overtones.
Each driver was specifically developed or tuned for the PM4 application. The entire system is purely pistonic; there are no driver break-up modes within 70db of the signal. The extremely stiff Nomex/Kevlar woofer diaphragms are driven by an exclusive dual magnetic structure. Energy storage is kept to a minimum, revealing dynamic contrasts without compression. The midrange diaphragm is an eggshell-thin ceramic material, driven by our unique dynamic magnetic structure. The neodymium magnetic structure of the tweeter energizes a diamond diaphragm. Its entirely in-phase output extends beyond 50Khz with no flexing or bending distortions.
The key to integrating the physical and drive elements resides in the electrical networks. As stated previously, these proprietary high-current circuits are derived directly from Tesseract. Absolute inter-driver phase linearity and low noise floor are maintained regardless of dynamic demand, ensuring image stability and black backgrounds even with the most demanding program material.
