∙Also, is your subwoofer turned “ON”? We don’t mean “is your sub- woofer amplifier on?” but rather, is your AVR sending a bass sig- nal to your sub amp? This can only happen if you say “Yes” (or “ON”) in the “Subwoofer” selection during the setup of your AVR’s setup menu.

∙Is your receiver connected to the sub amp? Use a well-shielded

“RCA” cable (sometimes called a “patch cord”) to connect the subwoofer output of your AVR to either input jack of your subwoofer’s dedicated amp. Again, you’ll need to “split” the bass signal with a “Y Cable” if you have a pair of subs. But you only need feed one of the two inputs (it doesn’t matter either Right or Left) of any SVS Powered Box sub.

∙Is your Radio Shack ® sound pressure level (SPL) meter ready? This tool is absolutely essential to proper home audio setup. It’s akin to a tire pressure gauge for your car. Set the meter to “Slow” and “C-weighting” (and turn the dial to 70dB. If using Avia for calibration tones, set your meter to 80dB instead.

Getting ready to start now: Make sure your receiver or proc- essor’s master volume is set to “00 dB” or some other easy to remember “reference level”. Then, ensure your sub’s volume/

gain control is set no more than 1/4 to 1/3rd up, for now, leaving plenty of adjust- ment “up”.

It’s also critical to check the subwoofer output level control of your AVR before you begin the test tones. Set the AVR’s subwoofer output to about 1/3rd up too. Turn off any sound-field processing schemes, “Mid-night Mode”, “DRC” (dynamic range control), “Movie Mode” etc. If it is an option in your system, route your LFE to the “subwoofer only”, not “mains + sub”.

Now play your AVR’s internal test noise “tones” so you have something to measure with your SPL meter. When the tones start alternating from speaker to speaker (watch your sound meter now), set each speaker’s volume to about 75 dB by using the receiver’s dedicated channel level controls (leaving your AVR’s master volume the same).

We recommend you turn down the AVR’s subwoofer channel output level before you significantly lower your subwoofer’s gain control. This helps keep distortion sent to your SVS to a minimum. Note: You should not set the AVR’s subwoofer level control much lower than the first 1/4th of the receiver’s control range. Some downward adjustment may be needed to fine tune levels later. If your subwoofer’s SPL meter reading is still too high, then turn down the sub’s amp volume a little with each run of the test noise signal, as it cycles from speaker to speaker and the subwoofer.

PC12-Plus, PB12-Plus specifications

SV Sound has made significant strides in the world of high-performance audio with its acclaimed lineup of subwoofers, including the PC12-Plus, PB12-Plus, PB13-Ultra, SB13-Plus, and PC13-Ultra.

The PC12-Plus is a compact, ported subwoofer that boasts a 12-inch driver capable of producing thunderous bass. Its cabinet design optimizes airflow, reducing distortion while enhancing low-frequency output. The built-in amplifier delivers 300 watts of continuous power, with peak output reaching up to 700 watts, ensuring that every rumble is felt as much as it is heard. The PC12-Plus is also equipped with adjustable phase control and low-pass filters, allowing users to finely tune their bass response based on their room acoustics.

The PB12-Plus features a similar design but emphasizes portability and efficiency. Also utilizing a 12-inch driver, it emphasizes the ability to generate room-filling bass without compromising space. The built-in amplifier matches the PC12-Plus in power, promising rich low frequencies ideal for both cinematic action sequences and music playback alike. Its robust cabinet construction allows for minimal vibration and resonance, maintaining clarity in sound reproduction.

For those seeking uncompromising power, the PB13-Ultra is a standout. This subwoofer features a larger 13.5-inch driver and an impressive 1000 watts of continuous power, peaking at 3700 watts. This model is engineered for serious enthusiasts who demand deep-reaching bass extension, and it excels in both music and home theater settings. The advanced DSP technology provides users with precise control over the subwoofer’s settings, allowing for an incredibly adaptable performance.

The SB13-Plus is a sealed subwoofer that excels in delivering tight, accurate bass response. Its design minimizes distortion while maximizing punch, making it an excellent choice for music lovers who appreciate precision. This subwoofer is equipped with similar power specs to the PB12-Plus, offering 300 watts continuous and 700 watts peak power. Its compact design makes it versatile enough to fit in smaller spaces without sacrificing sound quality.

Finally, the PC13-Ultra combines elements from its predecessors with upgraded specifications. Featuring an ultra-long-throw 13.5-inch driver and an expansive amplifier setup, it can produce overwhelming bass that resonates throughout larger spaces. It incorporates advanced room correction technologies, ensuring optimal performance regardless of placement.

In summary, SV Sound’s PC and PB subwoofers are characterized by their robust design, powerful amplifiers, and advanced technologies. Each model serves unique needs, offering powerful bass while maintaining clarity and precision, from compact designs for finesse in smaller spaces to large models that dominate in larger environments.
