Resounding Bass
The Kiwi Ears Quartet introduces Kiwi Ears’ innovative sobaric double dynamic driver subwoofer design, delivering bass that is deeper, faster, and more impactful than ever before.
More Information...Featuring two 10mm titanium diaphragm drivers, each powered by dual magnetic circuits and passively phase-aligned, the Quartet prevents soundwave cancellation for maximum efficiency. This unique engineering produces extended sub-bass kicks with exceptional clarity and punch, creating the ultimate fun and immersive listening experience for bass lovers.

Harmonious Balance
While bass-centric, the Quartet maintains a natural tonal balance that preserves clean mids and detailed treble without muddying.
More Information...A passive low-pass crossover at 350 Hz ensures thick, textured bass while keeping the mids flat and accurate from 350Hz to 1kHz. This tuning delivers the thunderous low end listeners crave, while still providing studio monitor-like neutrality and preventing unwanted bloat, resulting in a refined yet powerful sonic signature.

Custom Balanced Armature Drivers
The Quartet integrates custom mid-high and ultra-high balanced armature drivers for clean, detailed, and natural upper frequencies.
More Information...Using a tuned venting system for improved airflow, these drivers are carefully matched to the dynamic drivers and Kiwi Ears’ in-house target curve. The result is crisp and natural vocals, sparkling highs, and detailed treble that avoids harshness or fatigue, making the Quartet suitable for both professional and casual listening.

Recommended Usages
The Quartet combines studio monitor-like neutrality with enhanced bass, making it ideal for musicians and enthusiasts who demand impactful lows with balanced tonality.
More Information...With bass emphasis beginning at 350 Hz, the Quartet provides body and richness in the lower mids while retaining neutral mids and upper mids. Perfect for drummers, bass guitarists, and bass-loving listeners, it offers both performance precision and musical enjoyment.
