"Perhaps the most important speaker in a multi-channel surround system is the center channel. Enter the AC-300 from Energy. The AC-300 houses one 1 inch, magnetically shielded aluminum dome tweeter with cloth suspension and two 5 1/2 inch, shielded so called I.M. carbon/mica polypropylene woofers with compression molded N.B.R. surrounds. The AC-300 is a very good center channel for the money. It puts forth a very intelligible dialog never sounding distorted or overly bright."
