Description

Introducing the Amphion One18, a superior addition to your studio recording gear. Renowned for its transparent and un-hyped sound, the One18 offers an unparalleled listening experience. This high-end passive monitor integrates a custom-designed 6.5" woofer, a fast-response titanium tweeter, a high-density Corian waveguide, and a sealed enclosure with a passive radiator to deliver the natural sound essential for your critical mixing decisions.

The passive design of the One18 offers a distinct performance advantage. By keeping sensitive electronics away from magnetized moving drivers, overall monitor functionality is improved. This design also enables you to choose an amplification solution without constraints on enclosure size or overheating concerns.

The One18's Corian waveguide is another defining feature that controls and balances the sound. It enhances the tweeter's ability to couple with the air, extending down to the 1.6kHz crossover point and ensuring uniform system dispersion across a wide frequency range. This physical alignment of the drivers significantly improves time and phase coherence, resulting in a solid phantom center, pinpoint imaging, and an extra wide and deep sweet spot.

Key Features:

  • High-quality studio monitors designed for uncompromised performance
  • 2-way passive construction with rear-mounted passive radiator
  • 6.5" mid/bass woofer
  • 1" titanium tweeter
  • Power recommendation 30 to 150 watts
  • Provides a natural, transparent, un-hyped sound
  • Features a high-density Corian waveguide for control and balance
  • Delivers a beautifully honest listening experience
  • Ideal for tracking, mixing, and mastering
  • Ensures more accurate translation to any playback system

  • In smallish rooms (e.g., 2.7x3.7m), One18s might be overkill; owners suggest considering One15s for such spaces to balance cost and performance.

    Source
  • Amphion One18s are favored by mix engineers for genres like R&B, J-pop, K-pop, and hip-hop due to their ability to detect minute volume differences and compressor settings.

    Source
  • Owners suggest using a subwoofer with Amphion One18s due to inadequate low-end for bass monitoring.

    Source

Features and functionality

  • The Amphion One18s require a high-quality amplifier; some owners use models like the Adcom GFA-555 modded by Jim Williams for optimal performance.

    Source

Comparisons

  • Compared to Genelec 8040s, Amphion One18s offer clearer mids and highs but lack the hyped low-end, necessitating additional speakers for a full range check.

    Source
  • Amphion One18s are likened to older ProAcs and NS10s in terms of sound profile, making them familiar to those who appreciate these models' characteristics.

    Source
  • Owners who switched from Footprint 01s to Amphion One18s report significant improvements in mix quality, indicating a noteworthy difference in sound clarity and precision.

    Source

    Source

User experience

  • Owners emphasize the importance of room acoustics for Amphion One18s to fully leverage their revealing nature and prevent wasting investment in untreated spaces.

    Source
  • One owner noted that while Neumann monitors have appealing sound, their amplifiers are not repairable, leading to costly replacements if issues arise.

    Source
  • Some users add an Adam Audio subwoofer to their Amphion One18 setup for better bass response, as the Amphion sub is considered too costly.

Critic Reviews

Amphion One15 & One18

soundonsound.com

Amphion's One15 and One18 speakers are a testament to thoughtful electro-acoustic engineering, blending revealing and neutral sound with stylish aesthetics. The attention to detail in their construction is commendable, making them trustworthy tools for studio monitoring. However, as passive monitors, they require an additional investment in a quality power amplifier, which could be a drawback for some. Despite this, their clear, uncolored sound and lack of distortion make them a compelling choice for those seeking high-quality passive nearfield monitors.

Amphion One18 Review | jimalfredson.com

jimalfredson.com

The Amphion One18 speakers deliver an enchanting audio experience with exceptional mid-range clarity, precise imaging, and fatigue-free listening. The speakers' ability to "disappear" in the soundstage truly sets them apart, though their high price tag and need for a subwoofer to bolster low-end response might deter budget-conscious buyers. While not ten times better than the affordable JBLs, the Amphion's superior quality justifies the investment for those seeking unparalleled sound fidelity in their studio monitors.

Review: Amphion One18 Studio Monitors & Amp100 Amplifier — AudioTechnology

audiotechnology.com

Amphion's One18 studio monitors deliver an impressively honest and precise sound, focusing on midrange clarity with a wide sweet spot. While they aren't budget-friendly, their passive design avoids the compromises of built-in amps, allowing for flexible amplification choices. The monitors' lack of hyped frequencies may initially sound flat, but this accuracy ensures mixes translate well across mediums. With a robust build and solid bass response from passive radiators, they offer a superb listening experience for those who prioritize neutrality and detail. Ideal for critical listening, their only downside is the steep price tag.
