Compact in Size, Big in Sound
The word compact isn’t exactly something commonly used to describe a 12-inch subwoofer. However, looking at the small blueprint of the SA 12 D4 REV.3, it’s only fitting to use the said word when describing just how light and minimalistic this subwoofer is. This is especially impressive when you consider just how “big” these subwoofers sound when set-up.
Large Aluminum Faraday Ring
The aluminum faraday ring of the SA-12 D4 Rev.3 is huge, to say the least. Why is this important? Because the size is what’s responsible for minimizing the distortion and fatigue of this 12-inch subwoofer. As a result, the SA-12 D4 Rev.3 sacrifices a bit of its sound output. But in return, the SA-12 D4 Rev.3 can and should last longer than the rest of its competition.
This is arguably a far more important quality considering how pricey completing your car’s entire audio setup can be.
Highly Optimized Voice Coil Cooling System
Sundown Audio has proven time and time again that size doesn’t always matter. For example, with the Sundown Audio SA 12 D4 REV.3, the 2.5-inch voice coils don’t sound like much. But it’s able to squeeze out every bit of performance from it.
In addition to this, because of how it’s designed, the Sundown Audio SA 12 D4 REV.3 can compete with other subwoofers with 3-inch coil drivers, without the added bulk that usually comes with them.
The Sundown Audio SA 12 D4 REV.3 isn’t an enthusiast-grade subwoofer. It’s not even close. But for the average person, it might very well be. The dual 4-ohm voice coil can be bridged to 10ohm, giving you access to as much as 1,000 watts RMS in power. This is a lot of power for the average user. It’s arguably enough to transform what should be an entry-level bass system into something worthy of being entered in competitions.
There’s a reason why Sundown Audio is so popular among enthusiasts, and it shows even in their entry-level offerings like the Sundown Audio SA 12 D4 REV.3.
Sure, this 12-inch subwoofer won’t blow you nor your competition away. But it’s probably enough to make you fall in love with the importance of adding a high-quality subwoofer to your car’s audio system.
Think of the Sundown Audio SA 12 D4 REV.3 as the gateway drug, and once it’s got you hooked, you’ll find yourself looking at competition-grade options in no time.
