overall I be very pleased with the Panasonic sc-ht640w 5 dvd home Theater System . it sound great and be a great value for its price . it be extremely convenient not to have wire to the rear speaker . I do wish the rear volume be a bit louder , but again a minor problem for I . for those who have a wireless router -lrb- computer signal -rrb- you will likely get interference from the Panasonic Home Theater System . I do not have the spec on the home theater system , but it must also run on wireless Channel 6 , which be the same default signal for my wireless router . if this be you problem -lrb- drop wireless signal on computer -rrb- , you will need to reconfigure you wireless router to another channel . usually a wireless router have channel 1-11 . I set mine to channel 1 and now both system work fine .
