Useful beauty

Cabinets measuring 30.5x29x19 cm each weigh 8 kg in total. They can be placed on a shelf or hung on a wall for special canopies, and used as side and rear channels of a home theater. The cabinets are made of MDF and laminated with black and white PVC film. Curvilinear contours give the cabinets rigidity and acoustic inertia, contributing to less sound coloration due to side panel resonances. Anti-diffraction grills, designed by computer simulation, provide the speaker with an attractive design and minimize sound interference.

surround sound

Three emitters are located in two planes almost at right angles to each other. The 133 mm bass/mid driver received a polymer cone, and the 25 mm tweeters received a silk-polymer composite dome. The system reproduces sound in the frequency range of 50 – 27000 Hz and can operate in both bipolar and dipole modes.

Maximum sound purity

The high quality of sound is guarded by Dynamic Balance technology, which prevents distortion of the sound wave of the LF / HF driver due to dynamic suspension, and Acoustic Resonance Control (ARC) technology suppresses resonance in the cabinet, as a result of which the sound acquires maximum purity and naturalness. Deeper transmission of low frequencies is provided by a phase inverter.

FXi A4 are timbre-matched with other Polk Audio acoustic models, so they can be safely bought in addition to the main 5.1 set. and enjoy the voluminous and natural soundtrack of a movie or concert.
