Polk PSW505 Specifications

I normally use speakers with Polk PSW505 subwoofer cone diameter of 12 inches.

Polk PSW505 invariably uses cones of huge diameter as a result of the low frequencies involve the displacement of a big quantity of air.

Currently, the technology relies on amplitude greater than the dimension of movement rather than coming back to an excursion of regarding twelve mm.

Subwoofers are typically powered by an amplifier with adequate power and frequency dedicated to them is cut with a crossover circuit which ensures that mid and high frequencies from being sent to the subwoofer.

Polk PSW505 is equipped with cones twelve-in. usually inserted in boxes of plywood to thirteen layers.

For power 300 watts RMS, the Polk PSW505 subwoofer employed in the most effective stereo speakers are capable of reproducing frequencies of twenty eight Hz at -3 dB, with fidelity usually higher than that of a subwoofer.

There are special subwoofer, typically utilized in clubs are in a position to operate with powers larger than two hundred0 watts RMS at frequencies well below 20 hertz.

A subwoofer is very explicit the servo drive contrabass in that the speaker cone is moved by a belt driven by a motor. There is also a version with trumpet call BassTech-seven mainly utilized in theme parks.

Professional applications of Polk PSW505

The Polk PSW505 subwoofer is used in a skilled setting in live concerts, in theaters and when it serves to strengthen the sound in particular settings (nightclubs, theme restaurants, etc.) and in recording studios.

Polk PSW505 can be in a position to provide a high sound level from the moment that in a very home theater in terribly giant spaces. Generally, the employment in music will not would like to succeed in extremely low frequencies in distinction to what happens within the film but things is changing as a result of modern popular music often emphasizes this type of sound. The difficulties in this field then increase due to the distances at stake even a few hundred meters.

Polk PSW505 for Cinema

Some applications require a high noise level as that provided by the Polk PSW505 certified for use in the movie with THX sound.

The normal speakers in use in theaters, located behind the perforated screen, use cones with a diameter of fifteen inches will reproduce lower frequencies with a high sound pressure.

An unconventional use of the subwoofer was made when the movie Earthquake of 1974 for which it absolutely was used a system known as Sensurround to recreate the sensation of an earthquake.

This system was simply constituted by a set of enormous subwoofer designed to provide infrasonic that would be perceived, but not felt.

Polk PSW505 with Home Theater

For Home Theater system with an audience of thousands of spectators will use a lot of than twenty cases with 2 cones placed eighteen inches on both sides of the stage or in horizontal line below the stage itself.

Even the array of speakers used in massive concerts as well as the subwoofer. Most of the speakers is placed in an exceedingly higher position than the subwoofer is placed near the stage (to avoid problems like the Larsen impact) or in area in front of it to the right and left of the scene.

Polk PSW505 and Household uses

It is important to consider that a subwoofer will not necessarily mean better quality in the bass compared to a standard loudspeaker of medium or massive, is that just because a subwoofer must reproduce very cheap frequencies. A standard woofer should reproduce frequencies up to 200-300 Hz, or in a very box 2-approach audio, this woofer medium (as well as a tweeter) additionally reproduces the intermediate frequencies up to 3,0zerozero Hz and higher than.

The classical configuration of a multichannel system provides home-use tiny speakers (satellites) main (two for stereo and five or a lot of for surround) and place subwoofer elsewhere, so as to enhance the extent of the sound at lower frequencies and use a fanatical amplifier. The Polk PSW505 subwoofer can be part of one product that has the satellite speakers, purchased separately or included in the same container as other speakers (usually within the lowest position).


The distribution of audio systems with separate subwoofer and satellites is increased with the introduction of systems like lifestyle merchandise from Polk Audio and speakers for multimedia just like the Polk PSW505. In most audio systems is just a marketing move, especially for the most affordable devices: there is no reason why a little Polk PSW505 woofer in an exceedingly separate fund has higher performance than sensible speakers. Most subwoofer for multimedia systems should more appropriately be referred to as "woofers" as a result of they need the facility to be in a position to produce deep bass.

The little satellite systems are typically adjusted to breed the sounds higher than 90 Hz, giving an effect of localization to the subwoofer. On the other hand, domestic high-finish subwoofers are manufactured by firms like Polk Audio, these will be purchased separately to be added to existing systems. Polk PSW505 is often equipped with internal amplifiers.
