Compact Size, Full Sound
The Argon Audio FORUS 4 has been engineered for listeners who want quality hi-fi performance from a
compact loudspeaker. Its small cabinet makes it easy to position on shelves, furniture, speaker stands
or directly on a wall using the integrated mounting solution.
This makes the FORUS 4 particularly suitable for bedrooms, offices, apartments, smaller living rooms
and surround sound systems where larger speakers may not be practical.
4-Inch Paper-Cone Woofer
The 4-inch paper-cone woofer provides natural tonal characteristics and responsive
mid-bass performance. Voices and instruments are reproduced with clarity, while the speaker maintains
enough low-frequency extension for enjoyable everyday listening.
For listeners looking for deeper and more powerful bass, the FORUS 4 can also be combined with a
compatible powered subwoofer.
Soft-Dome Tweeter
A 0.75-inch soft-dome tweeter with neodymium magnet handles high-frequency reproduction,
delivering smooth treble detail without becoming overly aggressive. This helps provide a comfortable
listening experience across music, movies and television.
Scandinavian Design
The FORUS 4 follows Argon Audio's clean Scandinavian design philosophy. A lacquered front panel and
magnetically attached fabric grille give the speaker a minimalist appearance that blends easily into
contemporary interiors.
The speakers are available in Black, Walnut and White finishes, allowing them to
complement a wide variety of room styles.
