Tighter Bass – Thanks to UV-resistant 6.5-inch subwoofer box membrane
A UV-resistant 6-1/2 inch box membrane reduces flex and resonance within the enclosure, maintaining low-frequency fidelity. The sealed box design controls movement for cleaner bass response.
Stronger, well-defined bass that stays punchy rather than muddy, even when paired with lower-powered factory stereos.
Clear Highs – With balanced edge-driven dome tweeters
Balanced edge-driven dome tweeters manage dispersion and lower distortion across the upper frequencies, producing even treble. The soft, balanced profile reduces harshness while preserving detail.
Vocals and percussion sound more articulate, making long journeys less fatiguing and music more engaging.
Adjustable Treble – Thanks to external crossovers with 0/+2dB tweeter level control
External crossovers separate frequencies before amplification and include a tweeter level switch set at 0 or +2dB to match speaker placement and room acoustics. Physical crossover placement helps preserve signal integrity.
Allows quick tuning to suit different cars and listening preferences, helpful when moving tweeters away from factory mounting points.
