Discover Balanced Sound Quality with the Xcelsus XP620 Primum Speaker Pair

Tired of lackluster sound from your factory speakers? The Xcelsus XP620 Primum 6.5″ 2-Way Speaker Pair has been meticulously crafted to deliver a balanced and enriching audio experience.

Superior Tweeter Design

While most coaxial speakers feature a single tweeter, the XP620 sets itself apart with a dual 16mm Mylar tweeter array. This unique configuration extends frequency response, providing clear, precise treble that complements the bass.

Innovative Placement

Often, factory locations can muffle or dampen the quality of sound. Our forward-mounted dual tweeter array counters this, ensuring exceptional treble even when the speaker is mounted deep behind a door or trim panel.

Consistent, Rich Sound

The XP620 features an inbuilt Mylar 6dB crossover, ensuring that high and low frequencies are well-separated and delivered crisply. Your audio remains clear, whether you’re powering it through a high-power head unit or an amplifier.
