Hey everyone! I currently have a set of Logitech X-540's that i am using as a sound system plugged into the headphone jack of my 42" LG TV and was looking to upgrade to a real sound system. So ill just start off with what i am looking at buying: 1) 5 Piece Kevlar Driver and Ribbon Tweeter Surround Sound Speaker Set for SLS Q-Line Gold Home Theater System (from AV-Express) - $155 2) Sony STRDH820 7.1 Channel 3D AV Receiver (from Amazon) - $279 3) Acoustic Audio PSW-10 400 Watt 10" Audiophile Series Powered Subwoofer (from TheDeepDiscount) - $118 These three plus some standard cables for the entire hookup would total me just under $600. I was looking to get some feedback on this, and any suggestions if anyone has any better ideas. I haven't heard of SLS up until recently while looking for speakers, but they seem to be a very good deal for the price. I noticed that the sub and receiver were the weakest part of the system so i decide to just get the speakers and get a better Sub and receiver. Same goes for the Acoustic Audio Sub, but i read an owners forum for them, and everybody that has owned one seems to be pretty happy and the price seems pretty good for the quality of the product. The Sony receiver is fairly new so there aren't many reviews about, but the earlier model seems to have good reviews and is almost the same price. The other option i was looking at was an Onkyo HT-S6300 HTIB. This option would be much cheaper ( I am a college student with not a ton of money). I was wondering how the sound quality compared to the SLS speakers? Would it be that noticeable of a difference or should i save my money? I'm sure both of these would be a huge improvement coming from X-40's and would just like to get the best bang for my buck. My goal is to keep this setup under $600 so if you have any suggestions, please stay close to this number. The room these will end up in is a 10'x20' room. Thanks for the Help!
