Description
The Gamut Phi-3 is a 2-way bookshelf speaker built around a 150 mm woofer and a 25 mm dual-concentric ring-radiator tweeter. This compact format, with dimensions of 170 × 330 × 240 mm for a weight of 7 kg, allows for integration into restricted listening spaces, without requiring a large speaker.
The ring-radiator tweeter arranged in a dual-concentric configuration with the woofer aims for spatial coherence between the high and midrange frequencies, a point often sought after in two-way bookshelf speakers. The stated frequency response extends from 58 Hz to 40 kHz (± 3 dB), reflecting broad coverage towards the treble, beyond the human audible spectrum. The sensitivity of 86.5 dB combined with a nominal impedance of 4 Ω indicates that an amplifier capable of delivering sufficient power at low impedance will be required to make full use of the speaker.
This model is aimed at a listener with a small to medium-sized listening room and seeking accurate sound reproduction rather than high sound volume. Pairing with an amplifier suited to the speaker's 4 Ω impedance and moderate sensitivity will determine the result obtained when listening.

What to check before buying used
The suspensions of the 150 mm woofer deserve close inspection: the foam can crack or shrink over time, affecting bass performance. Also check the condition of the concentric ring-radiator tweeter, a delicate and costly component to replace if damaged. Finally, inspect the cabinet and edges of the compact enclosure, as well as the fixing of the connectors on the rear panel, sensitive points on a bookshelf format that is often moved around.
