Atohm GT3-HD

Dual 7" woofers per cabinet deliver deep, controlled bass — reviewer measured solid 25 Hz in-room and described the low end as tight with strong impact. The author explicitly stated most users would not need a subwoofer unless they are a "bass head," supporting excellent low-frequency performance for this class.

The ML150 mid driver is repeatedly called the "star of the show," producing a fast, incisive, natural midrange with great leading/trailing edge detail. Vocals are described as crisp and smooth with no sibilance, and multiple passages cite a very even, enjoyable midband.

Atohm's SD28 soft-dome tweeter is praised as refined, soft and accurate, with a copper ring to linearize response and reduce distortion. Reviewers noted excellent listenability and low fatigue; detail is very good though not of beryllium/AMT/ribbon reference extremes.

With modest toe-in (12–15°) the reviewer found an excellent combination of width and image-focus, citing convincing cello and violin authority and a smooth, linear in-room response from ~1 kHz upward. Imaging accuracy and soundstage width are repeatedly commended.

Dynamics are very good with solid slam and low-end authority, though the reviewer notes other designs (Spatial) have even greater perceived dynamics. The GT3-HD provides ample macro- and micro-dynamic control for most music, but isn’t presented as the absolute reference for explosive dynamics.
