Note: This is the original Classic SB1000 model and not the Pro model, so has no app control.

At first glance, it’s easy to underestimate the abilities of the SB-1000 Classic subwoofer. But when it erupts to life with deep and hard-hitting low frequency output, there’s no mistaking it as a bona fide, high performance home theatre subwoofer.

Commanding 12-inch SVS High Output Driver

SVS packed the compact SB-1000 Classic subwoofer with a front-firing 12-inch driver, dual high-grade ferrite magnets and FEA-optimised internal motor technology for high output with extremely low distortion. The lightweight cone material of the long-stroke driver reproduces subtle audio tones and massive low frequency impact with lifelike realism. Durable rubber surrounds ensure long-lasting performance, even when the subwoofer is pushed to its performance limits for extended periods of time, making the SB-1000 Classic a perfect option for serious music or home theatre lovers.

Powerful and Sophisticated Sledge STA-300D Amplifier

Driving the SB-1000 Classic subwoofer is an integrated SVS Sledge STA-300D amplifier with sophisticated DSP perfectly matched to the unique driver and cabinet configuration, and an equalisation curve optimised for enhanced transient response and room gain. The SB-1000 Classic subwoofer’s ability to start and stop on a dime and stay true to the source content is a performance hallmark normally reserved for much more expensive subwoofers. Conservatively rated at 300 watts RMS, 700+ watts peak power, the Sledge STA-300D amplifier maintains precise control of the subwoofer at all drive levels so you can push to reference volumes without distortion. The advanced DSP engine also allows for fine tuning of audio playback and easy set-up and integration into any home theatre or stereo system.

Innovative Subwoofer Engineering

Thermal management is critical when dealing with such a powerful amplifier and motor in a compact sealed cabinet, so SVS implemented a unique vented pole piece and efficient high-power voice coil to keep the SB-1000 Classic subwoofer cool without impacting performance or adding noise. The cabinet is rigidly braced and sonically inert so the bass you hear is always effortless and pure, even at the highest drive levels.

Weighing in at an easily movable 27 lbs, the SB-1000 is SVS’s lightest and smallest subwoofer, making its 24Hz to 260Hz (+/- 3dB) frequency response all the more impressive.

    Siless Hybrid 3-in-1 - Far Exceeded my Expectations!!!
    Model: SLH20025
    I recently installed the Siless Hybrid 3-in-1 sound deadening mat in my vehicle, and I’m genuinely impressed. For just $80 for 25 square feet, this product delivers performance that rivals materials costing twice as much — and with far less hassle. If you're on the fence......Just buy it! You will not be disappointed. Easy to Install: Unlike traditional sound deadening products that are stiff, sharp, and temperature-sensitive, this mat is soft, flexible, and easy to work with. I cut it cleanly with regular scissors and pressed it into tight spaces using just my fingers, so if in you don't have a roller or install tool, a good pair of scissors and your hands can get the job done. With other brands like Dynamat, the aluminum layer often leaves micro cuts on your hands and tears up your fingertips, but Siless does not due the acoustic layer being on top and above the aluminum layer that holds the butyl layer. So, it's very easy on your hands. Even in cooler temperatures (around 50°F), I had no trouble applying it but it goes on better heated. If warm outside, I would leave the entire box out in the sun for at least 30 minutes when it's warm or heats it's very pliable and easy to mold. Make sure its where you want it because once applied it's not ever falling off. and it became even more pliable and easy to mold. No heat gun, no mess — just straightforward application. I installed 40–50 square feet throughout the interior, covering everything except the headliner and the flooring forward of the rear seat. The difference in cabin noise is astonishing. I can turn my radio up concert loud with gut-punching bass, and from outside the car, it sounds like a factory sound system at mid volume. I was blown away by how well it contains sound — both inside out and outside in. My exhaust is pretty aggressive and now is barely audible from inside the cabin. While driving, it almost sounds like a stock factory setup. The Siless matting actually changed the driving experience and feels refined. If you're skeptical about sound deadening gimmicks, I get it, but this is the first product I've used and when I needed more, I went Stright to the 3 in 1 Hybrid matting and purchased it again. I love researching before buying and that's very uncommon for me to do. Note: Proper installation is key, and it does take time and patience. But if installed correctly and in the right places, it works better previously used from paint-on sound deadening to Dynamat. Update Nov, 2025 After using it this in 4 separate vehicles now. I feel the Siless’s 3 in 1 Hybrid has nailed it for best budget deadener that is better than dynamat extreme in performance and installation Protip: buy a roll of 2-3” aluminum tape and tape the seams. After trimming the edges tend to very sticky between the panels. I ran a strip of aluminum tape over the seems to create a better seal and true moisture I used it on four vehicles now and have I have not been paid to review and purchased every order myself. 3 in 1 Hybrid deadener by Siless is the best all around easy to apply sound deadner period!

    Top quality
    Model: SLH20025
    This Siless Hybrid 3-in-1 sound deadening mat is easy to work with and feels high-quality. The butyl material is thick and pliable, making it simple to cut and fit into doors, floors, or panels. After installation, road noise and vibrations are noticeably reduced, and it also seems to improve the overall cabin feel. No bad smell. At 25 sq ft per roll, it’s a good value for anyone looking to dampen noise and improve car acoustics. Overall, a solid, effective option for automotive soundproofing. Used on a Fiesta ST.

    Made a big improvement in cabin noise—highly recommend
    Model: SLH20025
    Siless Hybrid made a huge difference in reducing noise in the floor of my truck cabin. In some areas, there was basically just bare sheet metal between the inside and outside, so adding this really helped the truck feel more solid and noticeably quieter on the road. I used Kilmat on the doors, and honestly I wish I had used Siless Hybrid there too, but it was too late by the time I realized the difference. This material is very sticky, easy to cut, and simple to apply, which made the install pretty smooth. Just a heads-up: the tacky side gets messy and will bond to clothing really easily, so be careful during installation. Overall, I’d definitely buy it again—great product with real results.

    I wish I had Siless 20 years ago!!!
    Model: SLH20025, Model: SLH20025
    I have installed all kinds of insulation in vehicles over many years. I only needed to purchase 2 boxes to complete the entire interior siding of my 2025 chevy express, what a great value! I wanted to insulate my locksmith van for sound and heat. The sound reduction virtually eliminated the road noise. These panels also look amazing. It got up to 110F in the sun with the doors closed. After adding Siless insulation the temperature maxed out at 97F. That is a massive difference. Plus, I didn't even finish with the roof before testing. Siless Hybrid 3in1 was extremely easy to cut and adhere onto metal panels. I'm impressed with the quality of the individual panels and the adhesive is not toxic smelling compared to some others. My favorite thing about these panels is you can actually take them off and readjust them before they finally stick and they do not leave any black residue behind when you pull them up to adjust them. All I needed was a heat gun, knife and a roller to complete this job. The size of each panel is perfect, you can handle them with ease. I probably won't need your product again for a while, but when I do I will definitely be back.
