Kiwi Ears Septet | Quadbrid Universal IEMs

The Kiwi Ears Septet Fuses 7 Drivers, 4 Technologies and an Open-Back Design to Deliver a Truly Remarkable Audio Experience Quadbrid Driver Configuration: (1x) DD + (4x) BA + (1x) Planar + (1x) PZT Innovative open-back design for a spacious soundstage 5-way crossover design allows for precise driver control Offers engaging and balanced tone Perfect for both music enthusiasts and professionals 7 Drivers, 4 Driver Types The Kiwi Ears Septet combines seven drivers across four technologies—dynamic, balanced armature, micro planar, and piezoelectric—to deliver an exceptional audio experience with deep bass, clear mids, and smooth treble. The open-back design and custom tuning ensure a natural and expansive soundstage. 10mm Dynamic Driver The Septet utilizes the tried-and-true 10mm composite dynamic driver to power the sub-bass and bass. The large diaphragm dynamic driver outperforms other driver types for a powerful and deep sub-bass rumble down to 8Hz, and delivers a sub-woofer-like bass signature. Tuned precisely through both passive and acoustic strategies, the Septet offers hard-hitting bass that is rich, yet clean, for an uncompromising listening experience. 4 Balanced Armature Drivers Four balanced armature drivers have been selected to power the low-mid and mid-treble frequencies on the Septet. Balanced armature drivers offer an articulate, accurate, and detailed sound due to their speed, providing a studio monitor-like precision to your music. Two independent crossover networks are utilized across the four drivers, dedicating each channel specifically across the low-mid and mid-treble range for a complete coverage across the entire frequency range while minimizing harmonic distortions. Micro Planar Transducer The Septet features a single micro planar transducer (MPT) driver as its ultra-treble tweeter. The newly updated MPT has significantly enhanced output at high-treble frequencies, which elevates the clarity while minimizing distortion and artifacts in the sound. The natural texture and timbre of the MPT allows a smooth treble extension up to 30kHz to bring out every micro-detail and air in the music, without harshness. Piezoelectric Driver An updated PZT driver is featured in the Septet, enhancing the texture and clarity in the upper registers. Synched in unison with the MPT drivers, the PZT delivers extreme articulation that refines the perceived air across the entire frequency spectrum, helping to better define the resolution and soundstage and imaging capabilities. Open-Back Design The Septet has been designed as an open-back IEM, allowing full ventilation to every driver within. This design enables greater airflow and responsiveness to the drivers, while enhancing the soundstage and giving an ‘acoustic’ like texture to the sound. It’s an essential part of the Septet’s natural and immersive tuning. Extensive Engineering The Septet utilizes an all-encompassing 5-way passive crossover network, combined with acoustic tuning strategies and a three-bore nozzle system to provide a balanced and optimal tuning profile. The 5-way crossover spans over 4 driver types and 7 drivers to assign the optimal frequency ranges for each driver group, minimizing total harmonic distortion while boosting output.  Engaging and Balanced Tone The Septet targets the ideal balance between musical engagement and tonal accuracy. Intended for both music enthusiasts as well as professional sound engineers, the Septet features an impactful sub-bass shelf that cleanly transitions into the low-mid and mids, which is natural and free from artificial coloring. The treble range is crisp, yet maintained at a comfortable level throughout the entire curvature, allowing for an extended, yet smooth, performance across the highs.  Specifications Driver: 10mm Dynamic + 4BA + 1 Micro-Planar + 1 PZT (Open Back) Crossover: 5-way with 3 tuning tubes Rated Power: 5mW Max Power: 10mW Impedance: 15Ω Sensitivity: 95dB @ 1kHz/mW Frequency Response: 8Hz – 30kHz THD: <1% @ 1kHz Cable 5N OCC 0.78mm 2-Pin 1.2m ±5cm Plug: 3.5mm + 4.4mm interchangeable Kiwi Ears 1 Year Warranty In the Box Kiwi Ears Septet IEMs Cable 4.4mm adapter Case Eartips Warranty Card
