Hi, I'm looking at buying a sound bar for my lg ln5300 42" tv to go in my small college apartment bedroom. http://www.amazon.com/LG-Electronics-42LN5300-42-Inch-1080p/dp/B00BB0ZTO0/ref=sr_1_1?ie=UTF8&qid=1405623407&sr=8-1&keywords=lg+ln5300 and the 2 models that have caught my eye are the vizio s4251w-B4 ($190) http://www.amazon.com/VIZIO-S4251w-B4-Soundbar-Subwoofer-Satellite/dp/B00CDIK908/ref=cm_cr_pr_product_top and vizio s5430w ($120) http://www.amazon.com/VIZIO-S5430W-C2-54-Inch-Soundbar-Black/dp/B00E1EUX6M/ref=cm_cd_ql_qh_dp_t Which of these would be better? The s4251 is the same size as the tv, and it has 5.1 surround, but the $70 difference is a little steep. How will the 54 inch sound? Will I miss the sub that comes with the other? My max price is $200, although even that may be too much. Any other suggestions are welcome.
