... to address the subwoofer problem -lrb- which I run into myself -rrb- , it be not hard to fix . the connection cord be probably backwards and just need to be flip , or the subwoofer have not be turn on THROUGH the reciever . this be the first home Theater I have ever own . believe I when I be go to buy something like this I do lot of research . Research be what I do ! for about 2 month I read review after review , look at every system in every store , conduct interview of people who own system . after all that the Aiwa HT-D580 be what I choose . this have Dolby Digital and DTS decoder . it also have a pro Logic decoder which let you watch normal cable in surround . it have a great separation that put you in the movie . the subwoofer sound great . 50 watt may not sound like much , but it be power with little distorion even at high volume . this have a volume level of 50 . although the highest I have listen to it be 25 , and that be make my house shake . so it be definitly powerful enough for a large family room . it be also pretty easy to use all together , many thing be very self explanitory . the best thing about the sound be that it never be distorted even at high volume , many other system I look at do . if you do not have much money , want killer sound , deep bass that put you in the movie , Dolby Digital , pro logic and dt decoder , get this system you will be impressed !
