Most times that would include a subwoofer for bass and tweeters for added clarity. Coaxial speakers are known as two-way speakers. In 1954, The Acoustic Research Company released the Ar-1W, which was a high excursion woofer. They included their sub woofers into compacted sealed speaker boxes. The speakers’ bass went down to levels of 20 Hz without being hooked to an equalizer. Works Cited Cosper, Alex. Www.EHow.Com. Ehow Contributor. Web. 1-10-2011 Epand, Victor. Www.
