I recently saw this surround system, the Onkly GWX5.1 surround system listed on Outpost.com for $99.99. The unit has no DVD player, and the amplifier and Dolby 5.1 and DTS decoders are built into the subwoofer. It has 25 watts per channel. Has anyone had experience with this unit? I am looking to get this for my Dad since he already has a great Sony stereo system and Panasonic DVD player. He lives in a mobile home park so the 25 watts per channel power is about all he could use given the thin walls of his home. Actually, all I am really looking for is a 5.1 and DTS decoder and speakers. I don't think his Sony receiver will accept the 5.1 or DTS signals, hence the reason I am interested in this Onkyo system. Thanks.
