Input:
i have owned this center channel for almost 2 years now.  It took me almost a year to finally get it to where it sounded good, as others have stated it was very quiet and nobody could really hear any of the dialogue.  I recently purchased a new amplifier as this speaker is 4-8ohms and most amps are 6-16ohms.  having an amplifier with a lower ohm rating will push more power per channel which will in turn make the speaker sound better, i also used 12 guage wire which may be a little bit big but it made the speaker sound 100% better i can now hear everything in movies with no distortion at all
