PL- 28 center speaker includes two 8" poly- injected woofers. Like other top-rated BIC center speakers, the PL-28II is specially designed to recreate voices and center effects in movies rich in clarity. Delivering output to 119 dB (live rock band levels), the PL-28 includes a state-of-the- art 6 1/2" high efficiency aluminum dome horn tweeter.  As with all Acoustech horn speaker models, this exclusive tweeter produces such d etailed, startlingly lifelike sound that it will leave you speechless. All Acoustech Platinum Series speakers come in elegant enclosures with hand- rubbed black lacquer tops and bottoms. This extra step ensures each cabinet has a deep gloss shine that is more scratch resistant than many lacquer finishes on the market.
