The SA series has continually evolved over the years thanks to extensive testing and feedback from our customers but still stays true to its legendary design heritage.

FEA optimized motor & coil design capable of 19mm of one-way Klippel verified excursion and just over 33mm of x-mech. This motor & coil setup was then mated up to an extremely robust double-layer Nomex spider with fully tied-on “XL†tinsel leads (84-Strands of Conductor), an SPL competition grade paper cone, and a strong foam surround.

Product Features:

• Xmax = 19mm one-way by 70% BL
