This Listing Includes
- (2) Sundown Audio SA-Series SA6.5M 6.5" Speakers
The all-new 2025 Sundown Audio SA-Series SA6.5M is made for listeners who want real sound quality without giving up strong output capability. Designed as a versatile 6.5-inch midrange or midbass driver, it is an excellent fit for high-end component systems, sound-quality builds, and clean daily drivers that still need serious midbass punch.
The SA6.5M uses a woven carbon fiber cone and dust cap, along with a carefully engineered surround and spider assembly. These moving components were fully FEA simulated and Klippel verified to help deliver controlled response, reliable operation, and low-distortion performance.
With 5.9mm of one-way linear excursion by 70% BL, 7mm by CMS, and 6.28mm by LE, the SA6.5M offers impressive stroke for its size. Efficient motor venting, a revised custom-tooled frame with improved coil ventilation, and a thick magnet-ID Faraday ring help it stay composed when pushed.
Run it full range at 110W RMS, or use a 70 Hz high-pass filter to unlock up to 200W RMS of power handling. The SA6.5M is a fourth-generation SA mid driver refined for modern systems that demand smooth detail, strong midbass, and the output potential Sundown Audio is known for.
