Phase. Think of bass waves as conflicting or enhancing each other, depending on the timing of their arrival at your listening location (either together, or not). Since some of your HT bass might come from main, center and/or surround speakers, as well as your sub, getting these bass wave forms to arrive in a com- plementary, enhancing fashion is the difficult job of the phase knob. Essen- tially this control varies the timing of the bass waves coming from the sub. You can tweak this endlessly and not hear much difference; but don’t despair, the effect of bass cancellation will vary by volume and frequency in your room, and no one setting is likely to ever be “perfect”. One simple technique to opti- mize phase is to find a nice “bassy” loop (such as the menu of “Godzilla”) and measure the loop’s bass response at various bass SPL peaks. As the loop runs, you can make gradual changes to the phase knob. Where you see the most re- sponse on a given bass passage is the phase setting providing the least bass cancellation in your room (for the frequencies of the demo loop you chose).

Line In/Out. Use one of the sub’s “Line In” jacks to connect the subwoofer to the output jack of your receiver/processor. Feeding one input is enough. If you are using a conventional amp and/or a stereo setup you can use the “Line Out” jacks to send sound (filtered of bass information) back to your system amp.

Bass Boost. Your Powered Cylinder is tuned “flat” so that no bass boost is needed to get it’s full natural extension. Still, you might find the +3dB or +6dB “bump” (centered on the 30Hz range) sounds good. This may be espe- cially true if you listen to movies at a relatively low level. Be advised that such a boost can significantly lower available amp head-room. If you like to push your system to reference levels (loud!) we recommend running a 0dB boost.

Crossover By-Pass.If you allow your DD/DTS receiver or processor to man- age bass frequencies (recommended) this switch must be “ON”. This disables the “Crossover Frequency” knob and allows your sub to reproduce just what it’s fed from the receiver.

Power (with LED). “Off” is off. “On” is (always) On. And “Auto” allows your sub to switch itself on or off depending on whether there is a bass signal fed to it. Even if there is NO signal fed to the sub in this mode, the sub’s amp takes few minutes to switch off (so it’s not continually going off and on in a movie!). It turns on in a split second from it’s “sleep” mode.

High level inputs/outputs. Not commonly used today, but binding posts are there in case you don’t have low-level inputs/outputs on your receiver/ processor. Typically used if you are not using a DD/DTS compatible system.

A/C connection/Voltage Selector. Plug your sub into a dedicated A/C outlet. “Convenience” outlets of typical receivers often don’t provide the needed cur- rent. Select the correct voltage for your A/C system (115v. in USA).

Fuse. User replaceable with a 4 amp, 125 volt 5 x 20mm “Slow Blow” fuse. Fuses can be found at Radio Shack (Part Number 270-1066).

16-46PC, 20-39PC specifications

SV Sound, a renowned manufacturer of high-quality audio products, has established a strong reputation for delivering exhilarating sound performance in home theater and music systems. Among their acclaimed subwoofers, the SV Sound 16-46PC and 20-39PC stand out for their impressive specifications and innovative technologies, catering to both audiophiles and casual listeners.

The SV Sound 16-46PC features a 16-inch front-firing driver, designed to produce deep bass with remarkable accuracy and power. Its unique design allows it to reach frequencies as low as 16 Hz, making it perfect for replicating the rumble of cinematic explosions and the deep notes in music. The subwoofer is equipped with a sophisticated 500-watt RMS amplifier, providing substantial power to drive the driver effectively, while allowing for dynamic range in sound reproduction.

On the other hand, the 20-39PC houses a larger 20-inch driver, enhancing its capability to deliver even deeper bass and higher output levels. This model is also engineered for low-frequency extension, reaching frequencies down to 20 Hz, making it an excellent choice for enthusiasts who demand nothing short of an immersive audio experience. The 20-39PC features a robust 600-watt RMS amplifier, ensuring that it can handle demanding audio tracks without distortion.

Both models incorporate SV Sound’s advanced technologies, including a custom digital signal processing (DSP) circuit, which optimizes performance and minimizes distortion. The cabinet design for both subwoofers is built with high-quality MDF (medium-density fiberboard), ensuring durability while allowing for increased resonance and decreased vibrations that can muddy the sound.

Additionally, each subwoofer comes equipped with a phase switch and a low-pass filter, giving users the flexibility to tailor the sound to their personal preferences and room acoustics. The versatile connectivity options, including line-level and speaker-level inputs, ensure compatibility with a wide range of receivers and audio systems.

In conclusion, the SV Sound 16-46PC and 20-39PC subwoofers exemplify the brand's commitment to high-performance audio. With their powerful drivers, robust amplifiers, and cutting-edge technology, these subwoofers deliver exceptional sound quality that can elevate any audio setup, be it for movie watching or music listening. Whether you're a discerning audiophile or a casual listener, these models are sure to provide a thrilling auditory experience.
