SV Subwoofers

Parametric Equalizer (PB12-Ultra and select PB12-Plus subs only).

Important enough and challenging enough, this feature gets its own section! “PEQ” al- lows you to tame a “peak” in your room’s response. Peaks are quite common, especially in large rooms or ones where your sub is far from your listening position. NOTE: A Sound Pressure Level meter is a must for proper use of the PEQ, so get one before you tackle this control. TO DISABLE THIS CONTROL: Set the “LEVEL” control in the Parametric EQ feature until it stops on “MIN” — thus ensuring you do not inadvertently cause poor frequency response until such time as you properly configure the PEQ.

First you might ask yourself, “why use a PEQ?” The reason is quite simple. Your room. See, most times even a superlative subwoofer which measures very evenly (we say “flat”) in an open domain (no reflective boundaries) will not measure the same in your home theater or music room. Instead, colliding bass waves can build up and cause a “peak”. This is where a parametric equalizer helps out. A PEQ is an electronic circuit which al- lows the user to manipulate the input signal so the acoustical output is more desirable for their environment, in many cases allowing the worst peak to be “flattened”. By manipu- lating the input signal with your PEQ you can cut a wide or narrow peak in response lo- cated somewhere in the frequency range of the equalizer. Importantly, the equalizer found your sub only allows reduction of peaks, and is “cut only”, not a boost device.

Measure the room’s response. As indicated above, you must have a firm under- standing of your room’s acoustical properties before you use a PEQ. To determine your room’s natural response properties (and your subwoofer, in that room) you will need an SPL meter shown on Page 6, and at least a pad of graph paper and a pencil for charting as below. If you have graphing program similar to Microsoft Excel ® this will save some time graphing the response curves. The last item to correctly measure the room’s response is a test disc that can play specific frequencies. The disc should contain frequencies from 20Hz to 100Hz. One of the most popular frequency tests discs is Autosound 2000 CD #101. It can be found at www.carsound.com/cds.shtml and is quite inexpensive.

PB12-Ultra, PB12-ISD/V, 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. Each model is designed to deliver unparalleled sound quality and an immersive listening experience, making them ideal for both home theaters and music enthusiasts.

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.
