Subwoofers – The Speaker With the Big Bark

Subwoofers, or "woofers," have usually seemed quintessentially masculine to me. I suppose it's due to all of the young guys I've met who have shown me their car trunks, the entire interiors of which happen to be taken up with gigantic speakers. Yet as silly as it can sometimes appear, the subwoofer is an important component of any top quality music reproduction method.

Initial produced inside the 1960s, the subwoofer was developed in response to complaints about a lack of bass response in electrostatic speakers. For the initial decade or so, these loudspeakers had been identified only to music specialists and also the genuinely dedicated fans.

Then, in 1974, the film Earthquake was released in Sensurround. Inside the seventeen theatres exactly where it was shown, six very large subwoofers driven by a pair of 1600 watt amplifiers had been employed to simulate the sounds and effects of an real earthquake. This film and its use of sound were accountable for bringing subwoofers towards the public's focus.

Then within the late 1980s, the advent in the typically used compact cassette made it possible to add a lot more reduced frequency content material to recordings. The result was that subwoofers became more and more popular in domestic settings. Since that time, there has been an ever increasing recognition for subwoofers in residence stereo systems, residence theatre audio systems, and automobile audio systems. These days, it really is nearly impossible to go to a skilled concert or music venue that doesn't utilize the unmistakable resonances of a minimum of 1 subwoofer.

The introduction of Sensurround sparked a trend of subwoofer installation in cinemas. That program was succeeded by the Dolby Stereo 70 mm Six Track, which was in turn followed by Altec's devoted cinema subwoofer model, the 8182. Nowadays, the THX certification qualifications define the parameters for audio systems inside the cinema, including subwoofer needs. These requirements help to make sure that when "the audience is listening," they appreciate what they are hearing.

Additionally to industrial applications, almost all modern home theatre audio systems feature a subwoofer supplemented by two to five tiny "satellite" speakers. The benefit of having a subwoofer as part of an audio program is the fact that it allows the satellite speakers to become smaller with out sacrificing low frequency capability. Within a domestic setting, the subwoofer is typically separated in the other speakers and it is usually hidden within a cabinet or other piece of furniture. For optimum reduced frequency sound, experts advocate that the subwoofer be placed within a corner of the room, far from large room openings and close for the listener.

As previously mentioned, the automobile is the other popular place for subwoofer use amongst the general populace. Due to their dimension, most vehicle subwoofers wind up inside the back seat or, more generally, within the trunk. In this kind of an application, as a result of the normally tiny room of a car's interior, it is truly achievable for a subwoofer to generate dangerously substantial levels of sound pressure. Over time, such circumstances can result in hearing loss or tinnitus, that is generally indicated by an unidentifiable ringing or buzzing in an individual's ears.
