Description

Unparalleled Low Frequency Depth Power and Detail Chest-thumping slam and extreme low frequency extension with pinpoint accuracy and refined musicality – a level of subwoofer performance not seen at this price before. The SB-4000’s sophisticated DSP amplifier innovative driver and a sealed box design master room gain and command a space with deeper bass and higher output levels than what is typically possible from a subwoofer of its size. A top choice for audiophile music or home theater systems the SB-4000 sets all performance benchmarks for a subwoofer and leaves larger and more expensive subs trembling in its wake. The 4000 Series Sledge STA-1200D amplifiers use an efficient Class D design combined with fully discrete MOSFET output and a sophisticated Analog Devices DSP engine. The result is a level of effortless power and advanced processing not available from any other subwoofer manufacturer. High Current Output of Discrete MOSFETs with Efficiency of Class D Amplifier Combines the efficiency of a Class D amplifier design with the ability to move massive amounts of current through the fully discrete MOSFETs enabling immense low frequency output and precise driver control. Put simply outstanding real-world subwoofer performance at all drive levels. Sophisticated 50Mhz High Resolution Analog Devices Audio DSP Most advanced digital processor ever used in a subwoofer maintains pinpoint accuracy and pristine sound quality through advanced in-room tuning optimized frequency response curves powerful DSP controls and more. Room Gain Maximizes the subwoofer’s ability to take control of a room and benefit from the acoustic potential of the space it occupies by tailoring the roll off slope. The effect is accurate frequency response with staggeringly deep in-room extension – often as low as 10Hz - without the “boominess” commonly associated with room gain. Advanced Limiting Allows the amplifier to deliver all the way to the limits of it

    • It's big It's bold It's beautiful and sounds great
Style: Wired Color: Premium Black Ash
Review Image by Tony Wheeler Tony Wheeler
I have put off replacing a really good subwoofer that died on me years ago- until now. I'm glad that I purchased this SVS SB-4000. The technology has advanced allowing for some nice features; but it also sounds and works well which is the most important part. This subwoofer blends well with my tower speakers adding to the depth of my speakers and not just making them sound louder. A good subwoofer will extend the range of the main speakers- not just make the lows that are already there louder. This sub filled in the music on my main speakers as well as bringing life to action movies. So this subwoofer is not just good for movies, but is also musical. Listening to 2 channel music (2.1 actually) this subwoofer blends in to produce some strong deep bass from the drums in Jazz and Rock. The technology side of this subwoofer is also impressive. I was able to download the SVS app to my phone and I can control all aspects of this subwoofer from volume, to room profiling. It can be a lot to learn and try to adjust but fortunately, this sub is also designed to work with the latest home theater receivers using Audessy. I simply plugged my interconnect into the LFE connection on the back of the subwoofer and let Audessy do all the work. Afterwards I am still able to adjust the volume from my phone and even create profiles for music or movies outside of the Audessy settings. I can increase the volume until the bass is overpowering or put it back to the normal presets where it is hard to tell if the subwoofer is doing anything. That's how a sub is supposed to work. It should be seamless so that you have to go put your hand near the driver to see if it is actually working. SVS Customer support is outstanding. I received my new subwoofer on Friday evening after work. I got this big monster out of the box and set up but was not getting any sound. (Did the hand near the driver thing, put my hand on the driver even). I called the customer support number at just after 7 PM and somebody answered the phone! With his help over the phone we got my new subwoofer up and running. I was very glad someone was available so that I did not have to spend my weekend with disappointment. Instead I have had a fun weekend hearing explosions and the full range of music. ... show more

    • Game changer for my system
Style: Wired Color: Piano Gloss Black
Review Image by Mmath Mmath
Probably not as thunderous as it's ported counterpart, but this thing replaced to 12 year old 12 inch Polk 100watt subs. Pressurized my room better than the dule subs ever did. Watching Alien Romulus, the hair on my legs was vibrating. Super tight and not boomy. Great for movies and music. The thud hits really hard, and the low rumbles are felt deep in your gut. ... show more

    • The SVS SB4000 is a great product and has a great sound
Style: Wired Color: Piano Gloss Black
The SVS SB4000 is a great product and has a great sound. It has a lot of features and I specifically use the Iphone/Ipad app to make changes and to create and select presets for either music, movies, and the TV. I also purchased the SVS Isolation System (feet) with the four in the pack. The SVS SB4000 works like a charm. I was initially skeptical about using it with music. It adds a very good sound to it and I can control it. Gald I added it to my music, finally. I purchased it from IQ Entertainment that has great Customer Service to answer all your question. Also, SVS answers your individual questions vial email or telephone. I contacted them via email and they are very responsive. I asked about specific connection to my system. I had also tried the SVS SB1000 and 2000 but went finally for the SB4000 and glad I did. I would have gotten the SVS SB Ultra16 but my home space could not accomodate the size, but I am super happy with my SB4000. I had also considered the PB4000 but it was just too big and heavy and not what I really wanted. Again, I finally tried and added a subwoofer to my complex system, and glad I did and I really enjoy the SVS added to my system. The SVS SB4000 is connected to my McIntosh C50 preamp via XLR cables. SVS is a great product for the money and service ... show more

    • The sheer power is so impressive
Style: Wired Color: Premium Black Ash
What’s most impressive to me besides the build quality is how loud the low frequency effects can be if you choose. my Klipsch subwoofer always did a nice job, at least I thought it did. This SVS SB 4000 can play quietly and still blend with the front three speakers perfectly. However when you set your volume to watch a movie, the low rumbles are felt like you are a punching bag! I just sit there smiling. It’s really an awesome piece of equipment. The app makes set up easy if you know what you’re listening for. I always use a blend of music and movies for reference ... show more

    • An Outstanding Replacement
Style: Wired Color: Premium Black Ash
Our home theater was previously equipped with a JL Audio Fantom F112 V1 powered subwoofer when we purchased the house a couple of years ago. Unfortunately the F112 suddenly died, forcing us to look at a replacement/repair. The JL Audio equipment is way over priced for our needs in both repair or replacement, so we began to do our research. A friend suggested we look at the SVS line of powered subwoofers. After reading a few reviews and listening to a SVS SB-3000 I chose the SB-4000 as our replacement subwoofer and ordered from Amazon. It arrived in perfect shape, and required me to use my furniture hand truck to move into place. Make sure you have two health people to lift this thing as it weighs a bit over 100 pounds. The depth and richness this subwoofer produces easily kicks the wall down on movies like Top Gun, Avatar, and Polar Express. A wonderful addition to our home theater. So if you are considering adding a deep rich sounds to your home theater experience, look no further. Size is great, fits into the A/V cabinet just fine. Consider installing the optional isolation feet as it truly enhances the overall sound quality. 5 star, booming deep base that keeps kicking at a reasonable price. ... show more

SVS -4000 is one of the best subs on the market at any price....add a reasonable price and it’s in a world by itself. One provided a nice full room - duals (I bought the second one later) are unbelievable.
