SV Subwoofers

keep input distortion to a minimum, however you should not be set much lower than –5 dB recommended earlier, some adjustment room is needed to tweak down the road. If your subwoofer reading is still too high then turn down the sub’s amp volume a little with each run.

But what’s “too high”?? Tastes vary, and so do movie soundtracks, but your SVS is capable of tremendous levels of low distortion, low frequency bass — far more than most commercial subs. Take advantage of this, especially if you like action movies with lots of “.1” channel (LFE) action and give the sub a bit more during calibration. Keep in mind too that the human ear is relatively insensitive to low frequencies. This, coupled with the fact most folks don’t watch movies at Dolby Digital reference level (loud!), means tweaking the bass up a few dBs usu- ally yields a better movie sound experience.

What sub levels do we recommend? If you watch movies at relatively mod- erate sound levels, a range of +2dB to +3dB over your other channels is a good start. This means that the test tone will waiver about 78 dB for the subwoofer por- tion of the calibration run (88dB with Avia). (Note: You may rotate the sound meter SPL meter dial to the 80dB to get a good reading with these higher levels.) Note too that many modern surround sound receivers allow a variety of different subwoofer level settings, depending on the listening mode you are in. With “DVD” as your “source” use the above calibration routine. You may well find that CD stereo music calls for a lower bass settings. The above is a guide, experi- ment! The louder your master volume though, the more you should back off the sub level to compensate. 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 (center cushion, right?). Be ad- vised, strong bass levels can vary tremendously simply by moving a few feet.

Such is the nature of long wave-length, low bass sound. Don’t hesitate to try dif- ferent locations and different levels for your subwoofer. Calibrating too high (and often, too low) is the most common subwoofer setup error!

Powered Cylinder amp. We scoured the world for the best perform- ing sub amp (that’s still affordable). The result is a custom-designed, North American-made, rock steady amp with Mil-spec like build quality, and an unbeat- able feature set.

Volume. Use volume (in conjunction with your receiver’s subwoofer output level control) to come up with a bass calibration to your liking. Start calibration with the sub’s volume 1/2 to 3/4ths of the way up (or turned to the right).

Crossover Frequency. If you use your DD/DTS receiver/processor’s internal crossover to manage bass frequencies (highly recommended), the setting of this knob on the sub is irrelevant. (Note: You should use the crossover “Enable/ Disable” switch discussed below to take advantage of this configuration.) Other- wise this knob is used to best blend your SVS to your other speakers. Typically used in stereo only systems today.

20-39PCi, 16-46PCi, 25-31PCi specifications

SV Sound (SVS) has established itself as a sterling name in the realm of high-performance audio equipment, and the trio of subwoofers – 16-46PCi, 20-39PCi, and 25-31PCi – showcases its dedication to exceptional audio quality, innovation, and craftsmanship. Each model is designed to deliver powerful, deep bass reproduction, allowing audiophiles and home theater enthusiasts to enjoy a rich, immersive sound experience.

The 16-46PCi stands out with its dynamic 16-inch driver and a tuned port design, optimizing performance at both low and high volumes. With a frequency response that extends down to 16 Hz, it is capable of producing sub-bass frequencies with unparalleled accuracy. This model features a powerful amplifier, offering 500 watts RMS and peaking at 1,200 watts, ensuring robust power and minimal distortion even during the most intense movie scenes or musical performances. The 16-46PCi's cabinet construction incorporates high-quality MDF, which aids in reducing resonance and enhancing clarity.

Next in line is the 20-39PCi, featuring a larger 20-inch driver designed for deeper bass extension and pressure. Ideal for larger rooms, this subwoofer also offers a frequency response down to 20 Hz. The 20-39PCi employs a similar high-powered amplifier configuration with remarkable 500 watts RMS, peaking at 1,000 watts. Its rear-firing port design permits airflow that enhances both efficiency and sonic impact. This model excels in seamlessly blending with other speakers, providing a balanced sound that can fill large spaces without overwhelming the listener.

Finally, the 25-31PCi subwoofer targets those seeking an optimal mix of size and performance. With a 25-inch driver, it delivers impressive power and depth, producing frequencies as low as 25 Hz. The 25-31PCi is designed for ultimate flexibility, sporting a dual port configuration that allows users to adjust tuning based on room acoustics. Boasting similar power specifications as its siblings, it ensures that dynamic content is reproduced with tight control and precision.

All three models incorporate SVS’s proprietary technologies, such as adjustable phase control, low-pass filter, and variable gain settings, ensuring seamless integration with existing audio systems. Their stylish aesthetics, combined with exceptional build quality, make these subwoofers not only functional but also visually appealing additions to any listening space.

In summary, the SV Sound 16-46PCi, 20-39PCi, and 25-31PCi subwoofers cater to diverse audio needs, offering high-quality engineering that brings cinematic and musical experiences to life.
