Subsonic Filter and Port Tuning

Your new SVS subwoofer comes with cus- tom foam port plugs and variable sub- sonic filter which allows your sub to be “tuned” to even lower frequencies than its stock configuration. For most people and most rooms, your sub is already configured

for the best blend of extension (how deep/low your sub goes) and output (how loud it gets). However, we know bass is a very personal taste and no two rooms will react exactly the same with any subwoofer.

There are some compromises when tuning a sub lower than its standard configuration. Installing one port plug takes some capacity from upper reaches of bass, installing two port blocks limits upper bass “headroom” even more. So while deeper settings will indeed provide more bass down low (where DVD and music bass is more rare, but quite exciting!), you’ll sacrifice some total output capacity above the stock tuning point of the sub (where bass is more common). You should decide if the effect is pleasing on the sorts of movies and music you enjoy.

How to do it? Remove your grill by prying up with our fingers along its metal side. To insert a port plug, simply squeeze the foam on one end and press the plug into a port flare until it is about 1” lower than the edge of the surface of the sub. You can remove the plug by inserting your fin- gertips into the port flare and squeezing and pulling on the foam plug at the same time.

Blocking two ports is not recommended to avoid port chuffing. 25hz mode should be reserved for all ports open, maximum SPL configura- tions. Be sure to select the subsonic filter point on the back of your SVS amp which coincides correctly with your new “tuning point”. NOTE: We strongly recommend you do NOT run a lower subsonic filter point than your port plug configuration would dictate — especially if you are running the subwoofer at high sound pressure levels.
