SVS Subwoofer – SB-2000 Review that goes BOOM

If you have already bought a subwoofer then go for a perfect setup for the best results.

Because buying a great subwoofer doesn’t guarantee that you’ll wind up with great bass. You have to set up a subwoofer perfectly in order to experience quality music.

And as always, we’re here to guide you with your setup. Follow these steps and you will end up with a great setup.

Part-I: Placement and positioning

Placing the Subwoofer anywhere that’s convenient in your room may not be the best decision when it comes to getting quality bass.

To get the best experience there are a few things that you should consider while placing your subwoofer. 

  • If you have small speakers, it’s best to keep the sub within 3 or 4 feet of the front left or right speakers. The sub shouldn’t be much away from the speaker. 
  • If you have a skinny soundbar, keeping the sub as close as possible to the speaker. ideally.
  • If your speakers are larger (with 4-inch or larger woofers), you can experiment with placement. To do this play a CD with lots of deep bass > keep repeating the track > move the sub to all of the visually acceptable locations in your listening room. Once you are satisfied with the sound place it there. Try this over a couple of days as your ears will tire of trying to find the right spot.
  • You can also try a trick by placing the sub in your sitting/listening position and taking a little stroll around your room. Stopping in the spots where you’d like to place the sub. As you move around you’ll notice the bass’ apparent loudness and definition changes from place to place.

When you find the place that sounds the best to you, place the sub in that spot.

Part II: Connectivity and fine-tuning

Connect the sub with the home theater and the rest of the system. The single-cable Sub-In (or Subwoofer) connection will be the easiest and best-sounding hookup method.

  • Turn the volume control halfway up. 12’o clock if you think of it like a clock or 50% of however your volume dial is placed.
  • Adjust the Phase while playing the music. By default, it will be at 0 degrees, if you find the bass quite satisfying leave it there. If not, turning it into 180 degrees might be better. If you have an advanced subwoofer with a dial, you can play with it. Place yourself between the sub and the nearest speaker, play with the dial, and lock it when the bass sounds balanced.
  • Turn the sub’s (low-pass) crossover control knob to its maximum, highest numerical setting. 

Part III: Adjustment in the AV Receiver

There is nothing much you have to do If your AV receiver has an auto-setup program (Room EQ software like Audyssey or YPAO) built in it.

Run the complete setup routine with the calibration microphone that came with the receiver.

When that is complete, your setup is done.

If your receiver doesn’t have any auto-setup installed in you may need to do this manually. Stay with us, we will cover this in our next article.
