Design Ideologies
Experience a new level of performance with Stereo Integrity’s brilliantnew M350 midrange. This all-new design rethinks conventional midrange engineering with an innovative voice coil and spider arrangement. A massive 2″ / 50.8 mm diametre copper voice coil pairs with an internally mounted spider, positioned inside the voice coil former rather than below it. This unique layout provides generous, controlled spider movement while supporting the motor’s impressive 3.6 mm one-way linear excursion.
Improved Current Control
Increasing the voice coil to a full 2″ / 50.8 mm diametre dramatically improves thermal power handling in a compact 3.5″ driver. The lightweight copper winding is built on a Kapton former to reduce eddy currents while maintaining strength and efficiency. An all-new underhung motor design delivers greater motor force, improved sensitivity and 35% more one-way linear excursion than the previous generation; achieving 4 mm of linear travel with 70% BL.
Custom Engineering
A custom-engineered carrier joins the spider to the full carbon fibre dome, which serves as the driver’s radiating surface. Carbon fibre was chosen for its exceptional stiffness-to-weight ratio, allowing outstanding performance across the recommended 400 Hz to 5000 Hz bandwidth. The large dome also allows the internal spider to move freely; while the precision carrier keeps the voice coil, spider, dome and surround perfectly aligned throughout operation.
Clever Dimensions
Mounting depth has been reduced to just 36 mm, making the M350 30% shallower than the previous version for easier installation in more applications. A newly designed minimalist cast aluminum frame features a compact terminal block with direct-soldered voice coil leads for quick and reliable connections. The mounting pattern, cutout and overall diameter remain unchanged from the previous M3 Carbon, making upgrades simple and straightforward.
