GamuT is a Danish firm that is famous both for its high performance audio electronics and loudspeakers, with the four-model RS-series range standing as the firm’s flagship offerings. The RS range evolved from an earlier-generation of GamuT flagship models known as the S-series speakers, which first appeared in 2007. According to firm’s R&D Manager Benno Baun Meldgaard, the intent in developing the RS range has been to preserve and even expand upon the technical strengths of the S-speakers while significantly improving their overall musicality. Meldgaard emphasises that all RS models share nearly identical voicing, so that the main differences between the RS3 standmount model tested here and its bigger siblings is slightly deeper low-frequency extension and the ability to develop higher sound pressure levels in larger rooms. Even so, GamuT stresses that the RS3 offers unusually deep bass extension for its size and “performs like a full range speaker for smaller to medium-sized rooms”—a bold claim that we will put to the test in this review.
GamuT’s RS3 is a two-way standmount loudspeaker with a ported enclosure said to be “tuned for optimal impulse response.” The enclosure features a swept-back, boat hull-like design with heavy internal bracing and a rear-firing aluminium port. The enclosure walls are fashioned from a laminate composed of “21 individual layers of wood of various thickness and type”, while the cabinet, says GamuT, is “shaped for optimal damping using small amount(s) of damping material.”
The speaker’s driver array consists of a 38mm silk diaphragm, ring-radiator-type tweeter with a stainless steel phase plug and a Neodymium magnet assembly, plus a 178mm mid-bass driver fitted with a sliced, natural oil-impregnated paper diaphragm cone. Both units are sourced from Scan-Speak, but are custom configured to GamuT’s specifications. The crossover network, in turn, is said to be a “phase and impulse linear” design, while the speaker presents a four-ohm load that is said to be amplifier friendly and to have low phase shift. Sensitivity is a relatively low 86.5dB/2.83V, meaning the speaker likes to be pushed by amplifiers that can deliver a fair amount of power into four-ohm loads.
