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.

What bass levels do we recommend? If you watch movies at moderate sound levels, a good start is a range of +1dB to +3dB above your other channels (as measured with your sound meter). This means the test tone will waiver about 78 dB for the subwoofer portion of the calibration run using your receiver test tones.

Note too that many modern A/V receivers allow a variety of subwoofer level settings, depending on the “listening mode” you are in. With “Dolby Digital” as your “mode” use the above calibration routine. You may well find that CD “Stereo” music calls for a lower bass settings. The above is a guide… ex-periment! The louder your master AVR volume however, the more you should reduce the subwoofer’s playback level to compensate. You should always avoid your driver “bottoming”, resulting in a loud “clack”!

Location and measurement. You should take the above measurements from your typical preferred seat for watching movies. Be advised, strong bass levels can vary tremendously simply by moving your seat, or your sub-woofer, just a short distance. Such is the nature of long wavelength, deep bass sound. Do not hesitate to try different locations and different levels for your subwoofer.
Setting playback levels on the sub which are too high (and often, too low) is the most common theater/music setup error.

Seems it is the limitation on PC12-Plus, coz I saw some SVS PC13 user with two ports blocked.

Thank you for alzard's remind

The follow from 13U' manual

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.

Really depends on what kind of movie you watch - If you watch "Wanted", I strongly recommend using the 15Hz mode with 1 port blocked - the heart-beat sound is so cool !! Very deep bass and really shocking!!

根據外國測試﹐PC13U block port愈多distortion愈少。有人建議係買兩個PC13U block兩
個port﹐效果會非常好﹐價錢重平過買一個JL Audio F113好多(美國計)。

點解經常提JL Audio subwoofer﹐唔係特別針對。係JL Audio夠勁先會出黎比較﹐外國forum都係一樣﹐所以鼓勵大家去唔同forum睇下。 :)

係網友屋企試過﹐ PC13U x 2 (10Hz Tune) + AS-EQ1﹐好有世界末日感覺。 :P
