Sundown Audio - SA Classic Series 10" Subwoofer D2/D4
Here at Sundown Audio we take feedback from customers and dealers seriously. With the launch of the SA v.2 woofers we heard a lot of call to also keep the old version for lower depth / lower cost applications — so we did that via the “Classic” SA. Still available in 10s and 12s it is essentially the SA v.1 Rev.3 but with a black motor finish. We even squeezed in an upgrade… the motor is bolted together for enhanced long-term durability!
The Sundown SA series has been our most popular product line since the introduction of the SA-12 in 2009. It was the result of over a year of testing and prototyping until all of our goals and expectations were blown away. The SA series has continually evolved over the years thanks to extensive testing and feedback from our SPL competition Team and our customers but still stays true to its legendary design heritage. It has never failed to prove itself year-in and year-out in every application ranging from daily musical builds to all-out SPL competition vehicles.
When designing the SA series we started out with an 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. The motor also features a large magnet ID shorting ring (faraday ring) to reduce distortion causes by inductance & inductance variation over stroke.
Available in Dual 2 or Dual 4 Ohm Voice Coils
Features
Xmax = 19mm one-way by 70% BL
RMS Power = 750-watts
Vented magnetic gap
Optimized high-velocity pole vent
Innovative high-velocity vented frame spacer ring
Black Aluminum 2.5” voice coil former for superior heat dissipation
High Temperature copper voice coil wire
Large aluminum faraday ring (Magnet ID)
Spring Loaded Terminals
Stitched-On “XL” Tinsel Leads to prevent fatigue and failure
High strength cast aluminum frame
Optimized for small ported, sealed, & band-pass enclosures
These features combine to create the optimized coil ventilation system.
