Cerwin-Vega P-Series Powered PA Speakers Make Their Summer NAMM Debut

 

Cerwin-Vega P-Series

NASHVILLE, TN – There’s no shortage of powered PA speakers, but the P-Series from Cerwin-Vega has made DJs, solo acts, ensembles, bands, presenters, and others take notice of the extreme levels of power, bass, and clarity that the P-Series offers.

Massive, tight bass, coupled with crystal-clear sound quality at high levels, delivers the goods for the pros
DJs have particularly demanding requirements, because the sound has to be loud, clean, and have a defined low end that punches through on the dance floor—so it’s noteworthy that DJ Booth.net’s reviewer said “The Cerwin-Vega P1500X powered speakers are probably the best speakers that we have reviewed on DJbooth.net thus far in terms of build quality and overall sound quality.”

But the exemplary sound, punch, and super-durable construction are also welcome for any pro audio application. England’s prestigious Sound on Sound magazine said that “After working with the P-Series for a while, I’m left with an impression of toughness. They are built and perform solidly, and are capable of banging out loud and clear audio all day and night.” And Strother Bullins described the P-Series in Pro Audio Review as “One of the most impressive and unique portable PA systems…it remains my personal benchmark of what to expect from a truly pro-grade portable PA.”

The P-Series family consists of the P1500X (with 1500W peak power, 15" low-frequency driver, 1.75" high-frequency driver, and built-in 3-channel mixer) and the P1800X sub-woofer (with 2000W peak power and 18" low-frequency driver).

As Gus Jursch, Acting General Manager for Cerwin-Vega, states “We’re gratified that the P-Series is gaining such rapid acceptance from such a wide variety of users. It confirms that our decision not to cut corners, and instead focus like a laser on uncompromised performance, was what people truly wanted.”

What is the subwoofer?

Audio Knowledge
A subwoofer (or "sub") is a woofer, or a complete loudspeaker, which is dedicated to the reproduction of low-pitched audio frequencies known as bass. The typical frequency range for a subwoofer is about 20–200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-approved systems. Subwoofers are intended to augment the low frequency range of loudspeakers covering higher frequency bands.

Subwoofers are made up of one or more woofers mounted in a loudspeaker enclosure—often made of wood—capable of withstanding air pressure while resisting deformation. Subwoofer enclosures come in a variety of designs, including bass reflex (with a port or passive radiator in the enclosure), infinite baffle, horn-loaded, and bandpass designs, representing unique tradeoffs with respect to efficiency, bandwidth, size and cost. Passive subwoofers have a subwoofer driver and enclosure and they are powered by an external amplifier. Active subwoofers include a built-in amplifier.

The first subwoofers were developed in the 1960s to add bass response to home stereo systems. Subwoofers came into greater popular consciousness in the 1970s with the introduction of Sensurround in movies such as Earthquake, which produced loud low-frequency sounds through large subwoofers. With the advent of the compact cassette and the compact disc in the 1980s, the easy reproduction of deep and loud bass was no longer limited by the ability of a phonograph record stylus to track a groove, and producers could add more low frequency content to recordings. As well, during the 1990s, DVDs were increasingly recorded with "surround sound" processes that included a Low-frequency effects (LFE) channel, which could be heard using the subwoofer in home theater systems. During the 1990s, subwoofers also became increasingly popular in home stereo systems, custom car audio installations, and in PA systems. By the 2000s, subwoofers became almost universal in sound reinforcement systems in nightclubs and concert venues.
