SA-10/12/15: 

The SA line was designed to be the centerpiece of the Sundown Audio subwoofer lineup -- the line to which all of our other lines are compared.
We started with an FEA optimized motor design capable of 19mm of one-way Klippel verified excursion and significantly
more x-mech (maximum mechanical excursion).
This motor was mated to a top quality double layer nomex spider, an SPL competition grade paper cone,
and a strong foam surround capable of handling the excursion and force generated by the motor structure.
The motor also features dual faraday rings (shorting rings) to reduce inductive distortion.
At Sundown Audio this still was not enough so we designed a highly optimized voice coil cooling system that ensures that an SA series woofer
will never over-heat when used anywhere close to it's rated power level.
This system allows our 2.5" coil to match and exceed the thermal performance of many 3" coil drivers on the market today.
This same voice coil cooling system has been applied to all of our larger woofers lines as well due to it's proven effectiveness over the years in the SA series. 

All of this hard work and engineering has lead to the incredible reputation now enjoyed by the SA series worldwide.
We are very proud of what these woofers are capable of and we believe that they are one of the best woofers on the market today in their price and power range.
