INFORMATION FROM PRIOR V2 MODEL
When we set out to design our "SA" series component we knew it had to be something special; something to uphold the reputation of the SA series subwoofer line. The SA component set starts out with its custom designed midrange driver. The mid features a high quality cast aluminum basket as its starting point to ensure there are no frame resonances to muddy the sound.
The cone is a carefully selected blend of paper and wool fibers designed to damp any unwanted resonances. The dust cap is aluminum and its size, shape, and material were all chosen to create the type of sound we were looking for. The surround is a very compliant rubber that helps to tame any remaining edge resonances within the cone. With any midrange the cone, surround, and dust cap are CRITICAL to the sound. When designing the SA set we had little concern for fancy cosmetics or other "audio jewelry" -- we only wanted the smoothest sound possible.
The motor was FEA optimized in-house to increase linear excursion and features a full 6mm one-way linear excursion thanks to a carefully designed motor and extended pole piece. The v.2 SA component adds a large magnet ID faraday ring as well to keep inductive distortion to a minimum. We also thoroughly considered thermal performance in the design with the SA mid featuring a vented magnetic gap via channels in the back plate, vented voice coil collar, and a high-velocity pole vent. The 100-watt per side power rating on the SA mid is derived from a full 8-hour test on pink noise (full bandwidth down to 20 Hz) -- so when crossed over on the bottom-end this figure ends up being VERY conservative.
The SA series tweeter had to match the smooth sound of the midrange so we went with a silk dome. We tested numerous versions, tweaked the gap, dome material, tested various lenses, various chamber damping materials, so on and so forth until arriving at the final design. As the response graph is proof of the result is an incredibly smooth sounding tweeter.
The crossover is also relatively simple looking at first glance but it does the job perfectly. It is a 24 dB network centered at 3800 Hz with high quality air core inductors and Mylar capacitors. The crossover supports adjusting the tweeter from -3dB, to 0dB, to +3dB to ensure you can get the level of output you desire. Our crossover also features a built-in protection circuit for the tweeter – if too much power or a heavily clipped signal is present the tweeter will cut off temporarily to help prevent damage.
We are confident that anyone who is after a smooth sounding set will be incredibly pleased with the SA component line. Reviews have been overwhelmingly positive on them from all over the globe.

This component set looks great. Unfortunately, powering the set with over 100W, the tweeter protection circuit will come on. You really have to EQ down the tweeter or else you'll have the protection going off. It sucks because this happens at the volume where the set really comes alive. So you'll have great sound for a few minutes until the tweeter protection comes in. The crossovers suffer from inductor coupling, as well. The tweeters on this set are smooth and really easy to install. They have a silk dome and sound really clean. The mids require a ton of power, but have very clear midbass along with a smooth sound. The sound is almost clinical and lacks a bit of warmth, but I'd say these speakers are pretty smooth overall. If Sundown can fix the crossovers on the next revision, these would be amazing. As of now, these are an awesome set, but I advise running active and ditching the crossovers. For $400 I would've expected more from these speakers especially since Sundown usually makes great products.
Hands down absolutely amazing! These scream and have some of the best mid bass I have heard in a minute. They are super clean the crossover is easy too work with and keeps your tweeters safe! I have two sets of these on a salt 200.4 and they just take it no problem! Just buy them! For the crossover I did a stack mount application too save space just keep that mind.
Great product . Sure worth the money spend . Ready to buy another pair.
Just got these installed today and they sound great. Clear highs and crisp mids. They are definitely power hungry though so make sure to grab a 4 channel to go with them. I have not got my Sundown 4 channel installed yet but can’t wait to hear them really come to life. Other then the speakers down4sound has the best shipping and customer service in the industry. I will be purchasing my whole system through them as I go where the customer service goes. Thanks JP and the whole team for being the best you can be.
Just get them, they sound awesome. Loud and crisp!
Go ahead and spend the money on these. They scream and the sound quality if great. Thanks JP for recommending these.
These tweeters are the best built tweeters I have ever seen and the speakers well there sundown enough said on that
I'm really glad I decided to buy these they sound really good I have them hooked up to the first two channels on a sax100.4 and the sound quality is ridiculously good. Wasn't sure about spending that much $ on them at first but now I'm so glad I did.
