I am getting ready to purchase my first home theater system and I have pretty much decided on the Onkyo TXSR502 reciever, but I need some advice on the speakers. I like the looks of the Infinity TSS-450's $350.00 they are small and come with the wall brackets and wires, but lack the center rear speaker, which I could add for around $70.00 more. I also found the JBL SCS136SI on the BestBuy site. It is a full 6.1 system but doesn't have the wall mounts included. With all of that asside which speaker system is better? I haven't been able to hear either one, and I will probably buy online. I hope someone can help me out here. Any suggestions are welcome.
