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.

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.

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.

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.
