SVS SB-4000 Subwoofer (Black Ash) – 13.5-inch Driver, 1,200-Watts RMS, Sealed Cabinet, App Control

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.

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.

By far the best subwoofer I’ve ever owned. Its so good that I have run it at -15db.

I own several SVS SUBS & other speakers. The performance is excellent & as expected. However the unit’s physical appearance is poor w damage to the finish,. Much more than I expected.

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

This Sub is awesome! Put it in the best spot in the room and let your system do its calibration and WOW! Music and movies come to life.

Sounds great. Not sure about 1200 watt amp capability. I had a 12” ported sub with a Canadian made 600w amp board that had two huge 33,000 uF capacitors and freakin’ massive power supply coil (7” diameter, 3” thick) that was just as loud. That sub lasted 13 years while often played loud. I hope this one lasts just as long.

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.

Shakes the movie theatre. Exactly what we needed. Worth the price.

bon produit,bon fournisseur.

Awesome shipping great product

Sounds amazing but has trouble hitting the deep lows , 7/10 for price
