After trying these surround replacements, my speakers sound better than ever before! The perforated design creates an even distribution of sound, making my music and movies sound fuller and more immersive .The installation was simple and quick, so i didn`t have to spend hours tinkering with my electronics.

Overall, I highly recommend these replacements for anyone looking toSee full review
