I purchase these on sale more than a year ago from Amazon and they be amazing . I could not be more pleased with these speaker . I do not have a large room so for I this system be more than enough . I connect these speaker to my Denon avr 391 and when I be watch movie or play game the 5.1 be awesome ! I be not much of a technical guy when it come to sound but I know these speaker sure do not disappoint .
