A subwoofer is a specialized speaker responsible for the most difficult duty in home theater. It produces the very deep, room shaking notes that add a magical effect and balance the sound. This requires providing lots of power to fill a room with sound, and large mechanical motions of the subwoofer. When you hear about Dolby 5.1, the ".1" refers to the subwoofer's special role in a surround sound system consisting of five speakers and (at least) one subwoofer.

Although it is not mandatory, just like any other home theatre setup, to achieve a low, rumbling bass, a subwoofer is always highly recommended.

The CT4830 and CT4832 are almost identical cards with different PCI IDs (as programmed into the onboard EEPROM). A CT4832 card is generally an OEM version of the CT4830, although both cards might be marked as 'CT4830'. Neither kX Audio driver performance nor sound quality are affected by the way in which these cards are recognized by kX (the same applies to SB0090/SB0092 and SB0220/SB0222 cards).

Yes. Placing your radio in a cabinet, bookcase, near walls/counters or other hard surfaces will artificially inflate the bass. Some users have reported that placing several layers of tissue beneath the port reduces bass. Placement can also affect reception. Yes. Each tuner is hand calibrated at the factory but due to the nature of the analog dial, some variation is normal.

The longer the didg , the slower ones lips vibrate to match the change in the air pressure. At each length there is a different pressure required to kick start the vibrating drone of that particular didg. There is one other factor that can potentially make two didgs of different lengths have the same note. A didg with a substantial taper, compared with another didg the same length with an even diameter hole, will play a higher note than the even hole.

The digital signal of HDTV is integrated with 5-channel digital surround sound, providing the type of sound + picture experience you get with DVD players or in a theater itself. Note that a set of surround speakers is generally required to take full advantage of the home theater experience.

Currently, most HSU Research subwoofers are shielded, although extreme proximity of a subwoofer to a CRT (Cathode Ray Tube) television may produce streaks of colors. More and more TVs are not sensitive to magnetic fields, so this gets to be less and less of an issue. If you have a plasma, LCD, or DLP based TV, you do not have to worry about magnetic shielding.

To hook up a HSU Research subwoofer (any VTF or STF-3) to a pre-amp, a stereo pair of RCA cables are to be connected from the pre-amp line-level outputs to the subwoofer line-level inputs. This stereo pair output can be sourced from secondary line-level output jacks or by splitting the line-level output jacks by an (1 RCA male to 2 RCA female) adapter. This adapter can be found at Radio Shack.

Premier Poly-Cut? will remove lacquer and some urethane paints. It will not affect enamel or epoxy paints. Most machine tools are painted with enamel or epoxy paints.

This angular tip produces a more articulated cymbal response, but also has the heft to make it suitable for playing Rock. Bouncy and responsive, these tips produce fuller cymbal sounds and fatter drum sounds depending on their size.

Poly-MVA is a uniquely formulated nutritional supplement designed to provide energy for compromised body systems. It is helpful in increasing energy, reducing fatigue, and helping enhance overall health and well-being. It also addresses symptoms in people who are receiving chemotherapy or radiation treatments.

The vast majority of people should use a mono cable (connect it to the SUBWOOFER or LFE output on your receiver). Use stereo cables only with 2-channel stereo preamps.

You have a ground loop problem. Try using a cheater plug that removes the third prong, also called the 'ground'. Do NOT ground the grounding tab on the cheater plug! That would defeat the purpose of the cheater plug for this application. You have an amplifier problem. If the ground cheater plug does not help, disconnect all interconnects from the subwoofer amplifier. If still hums, call or email technical support. You have a problem with other equipment.

If the VSX 7000s does not have H.320 capability (which is also located in the subwoofer), then an alternate power cord can be purchased that will plug directly from the VSX 7000s into the wall. If H.320 capability is needed, then you cannot bypass the subwoofer.

A subwoofer's role is reproducing low frequency audio (bass). Subwoofers greatly enhance the bass response of a system, and are especially effective in a home theater environment. Since the recent trend away from larger tower speakers towards smaller satellite and in-wall speakers, subwoofers have become an important part of a complete system for full spectrum audio reproduction.
