SVS Image - 4 Reasons to Go With Dual Subs
If you’re in the market for a subwoofer, going “dual” can be a great option for a number of reasons. In this article the SVS Sound Experts explain why.

Reason 1: The first reason to go dual is to reduce the chance of phase cancellation, which occurs when two sound waves from a single home theater subwoofer cancel each other out, reducing the bass you hear. This happens when there is a delay between sound waves reaching your ears directly from the subwoofer and those bouncing off a wall or other room surface and reaching your ears an instant later. A single subwoofer is often at the mercy of a room, but dual subwoofers take control of the room with effortless, accurate bass.

Reason 2: The second reason to go dual is increased headroom. The combined power of dual subwoofers working in tandem results in greater dynamic range and deeper, more impactful low frequency effects that you can not only hear, but feel in your chest, your pant legs and elsewhere.

Reason 3: The third reason to go dual is because it makes the subwoofer harder to localize. Even with a fairly deep speaker/subwoofer crossover frequency, it’s often possible to tell where a single subwoofer is placed in the room, particularly if it is not located on the front stage. In comparison, dual subwoofers are nearly impossible to localize. Once listeners experience this immersive bass which seems to emanate from everywhere in the room, they never want to go back to a single subwoofer set-up.

Reason 4: The fourth reason to go dual is when décor and aesthetics are a factor since two smaller subwoofers are often easier to place and conceal, and because the combined output often exceeds that of a single larger subwoofer.

Once you’ve decided to go dual, the ideal placement is generally in opposite diagonal front and rear corners, but they can also be placed along the same front or side wall, or elsewhere, depending on your room’s layout.

Installing dual subwoofers is one of the easiest upgrades you can make to your audio system or home theater, and it can be the most impactful way to achieve accurate, room energizing bass.

What Makes a Great Subwoofer 5 Key Performance Attributes

Adding a subwoofer can be the most impactful upgrade you can make to the performance of an audio system or home theater. But a truly great subwoofer adds dimensions of impact, excitement, and low frequency extension without negatively impacting the overall accuracy and believability of the system’s sound. Here are five key attributes all of the best subwoofers must possess.

  1. Have outstanding low frequency extension – This seems obvious, but many subwoofers don’t have the ability to reproduce the deepest bass, so attempt to make up for it by exaggerating the mid-bass performance to address the deficit. A great subwoofer is capable of delivering all the low frequencies in the content being played, sometimes at frequencies so low they can only be felt, not heard!
  2. Be able to produce those low frequencies at the highest sound pressure levels (SPLs) – A great subwoofer plays effortlessly loud and distortion free, no matter how demanding the source material.   Lesser subwoofers use amplifier limiting to cap output, resulting in the bass “disappearing” when the listener turns up the volume past conversational levels.
  3. Be accurate in terms of frequencies produced, and NOT produced – A great subwoofer adds no sonic signature and is completely faithful to the source content delivering the bass notes or low frequencies exactly as the artist or director intended. Lesser subwoofers deliver boomy “one note” bass that is never convincing or enjoyable.
  4. Have speed and control in transients to stop and start reproducing bass according to the actual program content – A great subwoofer has speed in musical or cinematic transients so as to keep pace with the content. Lesser subwoofers can’t keep up with the content or the full range speakers, making the overall system sound smeared and undetailed.
  5. Blend seamlessly with full range speakers – Subwoofers are great, but in order to function properly they must be a seamless part of the overall sound of the system, never drawing attention to the bass alone.

From strumming bass guitar riffs and drum beats to the most complex and demanding movie sound effects, a great subwoofer reveals deep layers of sound a speaker is simply not equipped to handle. And while some subwoofers merely add bass, a truly great subwoofer elevates the listening experience in a unique and visceral way.
