The all-new 2025 Sundown SA speaker series has been designed to make a statement. What statement, you may ask? That Sundown Audio can be just as serious about SQ as we are about SPL. Many people already know this but our subwoofers – even the ones used for crushing demos – have some of the lowest distortion on the market. We are now bringing our unique approach to the more dedicated Sound Quality market.Starting at the upper end of the frequency spectrum we have the SA-1T Tweeter. The SA-1T features a 25.5mm silk dome (total 38mm including surround) driven by a powerful neodymium motor structure. The dome features a compact, tuned back chamber which helps it to achieve its extremely low FS around 700hz. This gives you an enormous amount of flexibility in choosing the crossover. The tweeter can be used as a 2-way with the 6.5M or the 8M models or as part of a three way with either and the 3M model. In addition to the low FS and smooth response the SA-1T has a very high 92dB sensitivity so it doesn't take much power to get loud enough for just about anyone. The SA-1T is the 4th generation SA tweeter building on the success of the tweeter found in the SA Component sets over three generations.Headed down the spectrum to the midrange we have the SA-3M. This "little" unit is something incredibly special and is a favorite project of lead product designer / founder Jacob Fuller. We really went all-out on this unit to address the "big 3" drivers of distortion. The SA-3M features 4.5mm of one-way linear excursion by 70% BL (with 8mm x-mech thanks to the custom tooled frame – so no bottoming out even on powerful dynamics) and over 6mm by CMS and LE definitions on Klippel. There is essentially NO risk of the driver reaching linearity limits in most applications. The beefy motor structure is a combination of ferrite and a neodymium pole cap magnet to help us reach 84.5dB sensitivity at 1-watt. There is a double LE treatment internal to the motor via both a copper pole sleeve an

There is essentially NO risk of the driver reaching linearity limits in most applications. The beefy motor structure is a combination of ferrite and a neodymium pole cap magnet to help us reach 84.5dB sensitivity at 1-watt. There is a double LE treatment internal to the motor via both a copper pole sleeve and an aluminum magnet ID shorting ring allowing the SA-3M to play full-range to beyond 20khz (although, for several reasons, we do suggest using a tweeter for the top-end). On the bottom end they can be high-pass crossed over at 300hz effortlessly with 150-watts of power handling (thanks to the 28mm diameter, extra-long voice coil) or even lower if needed, with less power, due to the incredibly high linear stroke. The suspension system, surround and spider, of the SA-3M took over a year of FEA simulations and testing to reach perfection and is just as important as the motor to the resulting low distortion. We gave the suspension just as much attention as we would for a full blown high-stroke subwoofer. To finish off this masterpiece we tested several different types of woven carbon fiber cones & dust caps to achieve the best FR possible. To finish off the 2025 SA speaker line we created the SA-6.5M and the SA-8M. Both of which can be used as a mid-bass or mid-range speaker depending on your application. Both drivers feature the same attention to detail as the 3M regarding the carbon cone and dust cap, surround, and spider. All of these parts were fully FEA simulated and Klippel verified. The SA-6.5M features 5.9mm one-way linear excursion by 70% BL, 7mm by CMS, and 6.28mm by LE on Klippel. Thanks to the efficient motor venting and ample voice coil the power handling is rated for 110-watts full range / 200-watts with a 70hz HPF filter with a respectable 89dB sensitivity. As with the SA-1T this is a 4th generation SA speaker due to the SA component set from prior generations. For this iteration we optimized it further and also created a new custom-tooled frame. The revised frame is more aerodynamics and also allows for superior coil ventilation. As with most Sundown products you will find a thick magnet-ID Faraday ring as well. Last, but absolutely not least, we have the SA-8M which takes linear stroke to yet another level. We were able to achieve 9mm one-way linear by 70% BL and nearly 10mm by CMS and LE standards. As with the 3M, the 8M features a pole sleeve and magnet ID faraday ring for LE treatment. This unit is an absolute powerhouse for mid-bass, and we believe it will make big waves in the SQ world. On the output side it has a 91.5dB sensitivity and will handle 130-watts full-range / 250-watts with a 70Hz HPF thanks to the efficient motor venting and huge 2" coil. The SA-8M is all-in on SQ and output potential – the Sundown way!

Hear the difference quality makes.

When Sundown set out to design the "SA" series component they knew it had to be something special; something to uphold the reputation of the SA series subwoofer line. But at the same time the price had to remain reasonable; something that almost anyone can afford. 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; where many speakers in this category go with cheaper stamped steel frames. The cone is a carefully selected blend of paper and wool fibers designed to damp any unwanted resonances. The dust cap is a soft poly whose size, shape, and material were all chosen to create the least amount of breakup and distortion as possible. 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 no concern for fancy cosmetics or other "audio jewelry" 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. We also thoroughly considered thermal performance in the design with the SA mid featuring a vented magnetic gap and a vented voice coil collar. The 60-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. Most customers use 100+ watt RMS amplifiers on the SA sets. 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. Don't be fooled by the simple housing -- as we are all taught not to judge a book by its cover and you will find this tweeter performs as good or better than many fancier looking counterparts. We stuck with the Sundown mentality of not spending money where it doesn't increase performance. The crossover is also relatively simple looking at first glance but it does the job perfectly. It is a 12 dB network centered at 3800 Hz with high quality air core inductors and Mylar capacitors. It also features the ability to change the LPF on the mid from a 12dB, to 6dB, to a bypassed slope as well as to adjust the tweeter from 0, to -3, to -6 dB levels. 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. If you are a metal or hard dome tweeter fan it may not be your set but we will develop a "sharper" sounding set down the line!

The SA-1T is the 4th generation SA tweeter building on the success of the tweeter found in the SA Component sets over three generations. Headed down the spectrum to the midrange we have the SA-3M. This "little" unit is something incredibly special and is a favorite project of lead product designer / founder Jacob Fuller. We really went all-out on this unit to address the "big 3" drivers of distortion. The SA-3M features 4. 5m m of one-way linear excursion by 70% BL (with 8mm x-mech thanks to the custom tooled frame – so no bottoming out even on powerful dynamics) and over 6mm by CMS and LE definitions on Klippel. There is essentially NO risk of the driver reaching linearity limits in most applications. The beefy motor structure is a combination of ferrite and a neodymium pole cap magnet to help us reach 84.5dB sensitivity at 1-watt. There is a double LE treatment internal to the motor via both a copper pole sleeve and an aluminum magnet ID shorting ring allowing the SA-3M to play full-range to beyond 20khz (although, for several reasons, we do suggest using a tweeter for the top-end). On the bottom end they can be high-pass crossed over at 300hz effortlessly with 150-watts of power handling (thanks to the 28mm diameter, extra-long voice coil) or even lower if needed, with less power, due to the incredibly high linear stroke. The suspension system, surround and spider, of the SA-3M took over a year of FEA simulations and testing to reach perfection and is just as important as the motor to the resulting low distortion. We gave the suspension just as much attention as we would for a full blown high-stroke subwoofer. To finish off this masterpiece we tested several different types of woven carbon fiber cones & dust caps to achieve the best FR possible. To finish off the 2025 SA speaker line we created the SA-6 . 5M and the SA-8M. Both of which can be used as a mid-bass or mid-range speaker depending on your application. Both drivers feature the same attention to detail as the 3M regarding the carbon cone and dust cap, surround, and spider. All of these parts were fully FEA simulated and Klippel verified. The SA-6 . 5M features 5.9mm one-way linear excursion by 70% BL, 7mm by CMS, and 6.28mm by LE on Klippel. Thanks to the efficient motor venting and ample voice coil the power handling is rated for 110-watts full range / 200-watts with a 70hz HPF filter with a respectable 89dB sensitivity. As with the SA-1T this is a 4th generation SA speaker due to the SA component set from prior generations. For this iteration we optimized it further and also created a new custom-tooled frame. The revised frame is more aerodynamics and also allows for superior coil ventilation. As with most Sundown products you will find a thick magnet-ID Faraday ring as well. Last, but absolutely not least, we have the SA-8M which takes linear stroke to yet another level. We were able to achieve 9mm one-way linear by 70% BL and nearly 10mm by CMS and LE standards. As with the 3M, the 8M features a pole sleeve and magnet ID faraday ring for LE treatment. This unit is an absolute powerhouse for mid-bass, and we believe it will make big waves in the SQ world. On the output side it has a 91.5dB sensitivity and will handle 130-watts full-range / 250-watts with a 70Hz HPF thanks to the efficient motor venting and huge 2" coil. The SA-8M is all-in on SQ and output potential – the Sundown way! Sold As A Pair Specs Coming Soon

The all-new 2025 Sundown SA speaker series has been designed to make a statement. What statement, you may ask? That Sundown Audio can be just as serious about SQ as we are about SPL. Many people already know this but our subwoofers – even the ones used for crushing demos – have some of the lowest distortion on the market. We are now bringing our unique approach to the more dedicated Sound Quality market. Starting at the upper end of the frequency spectrum we have the SA-1T Tweeter. The SA-1T features a 25. 5m m silk dome (total 38mm including surround) driven by a powerful neodymium motor structure. The dome features a compact, tuned back chamber which helps it to achieve its extremely low FS around 700hz. This gives you an enormous amount of flexibility in choosing the crossover. The tweeter can be used as a 2-way with the 6. 5M or the 8M models or as part of a three way with either and the 3M model. In addition to the low FS and smooth response the SA-1T has a very high 92dB sensitivity so it doesn't take much power to get loud enough for just about anyone.

The Sundown Audio VEX series is our top-of-the-line high efficiency mid-range series. The first entry, the VEX-10, was designed to make a splash featuring a 500-watts RMS power rating thanks to its enormous 3” coil (with a full 20mm winding length) and highly efficient airflow system consisting of twelve gaps vents and a chamfered, large-diameter pole vent. The long coil also affords the VEX-10 a full 9mm of linear x-max one-way so it can play lower than many other high-efficiency drivers without distortion. The inductance is kept in check by a dual shorting-ring system (magnet ID & pole cap) which drops the LE spec to less than 25% of the RE value. This allows the high-frequency extension to reach all the way up to 4,000 Hz where it then falls of naturally and smoothly on its own thanks to the extremely strong and non-resonant carbon-fiber cone & dust-cap assembly. Most high-efficiency drivers utilize very light- weight paper which is great for sensitivity but not so great in terms of breakup modes and strength (to withstand torture in bass-heavy vehicles). We went with real carbon-fiber to address these issues at the expense of more mass. But we still achieved a 96.6dB sensitivity by combining a large diameter, high- strength ferrite motor with a neodymium pole-cap magnet! The whole package is held together with a sturdy cast-aluminum frame that features extensive spider cavity venting to further increase thermal power handling. Quite simply – if you are looking for one of the loudest and best-sounding high efficiency midrange drivers to hit the car-audio market the VEX-10 is exactly what you need!
