  1. best subwoofers i've ever owned

    Posted by Brendan on 27th Mar 2015

    I owned a pair of these a couple years ago and eventually had to get rid of them. I wanted to run a pair of 15s again and I had to go with the SA 15s. They still amaze me. They hit the lows flawlessly and even perform on the higher end. I have them in a sealed box because I don't have room for a ported box but they are still extremely loud and can be heard and felt from a good distance. I'm giving 1000 watts to each of them and they sound amazing. They blow my old alpine type rs away. Great for SPL and SQ.

  2. Amateurs Don't Know How To Install

    Posted by Car Audio Tech on 4th Mar 2015

    I see a couple people on here saying the SAs are garbage or can't handle power etc etc. Apparently they don't know how to build a box and tube it to the right hz. It's more to installing a subwoofer than just slapping it in a box and throwing an amp on it. You can't expect it to perform optimally under those conditions. Do some research, if you can't install it right get someone else to do it. You are bashing an excellent product that you didn't do your due diligence on for it to function properly.

    I have 1 SA 15 dual 2 ohm that I replaced a kicker cvr 15 dual 2 ohm. The SA slams ridiculously. I am getting roof flex and I am wired @ 1 ohm. Box is 5.4 cubes tuned to 32 hz. I will be getting a nightshade next.

    I am Happy With The Product. I am Glad You Guys Place A Second Box.Pluse Extra Protection Inside The Box.The Outer Box Was Damage. But The Speaker Was Fine.I Can Expect That From U.P.S.But Thanks Again.

  6. don't bash sundown

    Posted by Unknown on 20th Feb 2014

    To the kid who is bashing the Sa's. I'll have you know I have 1 sa 15 d2 in a 5.1 cubic foot box tuned to 36 hertz. On a hifonics brutus 1600 at 1 ohm. I have embarrassed cvrs, solo barics, cvxs, and even solo xs, and did I mention my single 15 does 148.2 on the dash sealed up sundown is on a much higher level than kicker will ever be. Sundown has the trophies to prove it bud.

  7. BEAST

    Posted by James on 5th Oct 2013

    I currently own 8 sa 15 d2's 6 in a 1986 chevy blazer with a 4th order and the 2 other's in a 2002 Mitsubishi eclipse walled 4th order these subs are amazing and clean current have a hifonic's 2400d in the eclipse at 1ohm and the subs love every watt of power!! currently no amp in the chevy i had no problem with ssa in anyway shipping was fast and cant beat the price of these beasts! the chevy blazer will soon have a sundown 5000d and the eclipse with a sundown 3500d v.2

  8. You got to be kidding me

    Posted by daddiescaddy on 30th Jul 2013

    I recently purchased 2 sa 15 dual 2. They are replacing kicker cvr 07 154. The box is the same and amp which is a kicker zr1000 tuned for deep bass. The gain on amp is quarter turn back from half and these subs are garbage compared to kicker. My car was micked at 147 dbs wit the kickers. These subs can't take a pounding like u guys are saying in these blogs. To make a long story short sundown entry-level subs are no way in the same league as kicker comps.

  9. 900 watts rms

    Posted by Bobby Cruz on 26th Apr 2013

    this sub is good and at a affordabale price. i own 2 of these and 900 watts rms on each sub. they can handle the beating

  10. decent

    Posted by John on 26th Jan 2013

    This sub is decent and can handle power but tends to sound peaky with a lot of notes at 600 to 1000 rms there is a lot better options out there i just purchased 2 AUDIOBAHN AW1200J subs after owning one of these and I can say in my opinion the audiobahns destroy one these and then some and these subs are overrated yea they handle 1000 rms but sound like shit doing it.

** T/S Specifications measured with coils in series

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.

We realized that this still was not enough to meet our goal of delivering the best driver on market in this price range to our customers. To that end we designed a highly optimized voice coil cooling system that has since found its way into almost every other subwoofer we make to this day. This system allows our 2.5" coil to match and exceed the thermal performance of many competing 3" coil drivers on the market without requiring the usage of a much heavier voice coil than required for the design. The result is that the SA features the ideal mix of mass & stiffness to give you the best performance in nearly every type of enclosure.All of this hard work and engineering has led 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 hands down for the money.
