the clock is ticking on starting my new homes, include a dedicated home theater. my budget is around $2k for speakers, including a sub. with all the talk about SVS subs, i think $500 of that will go towards a woofer, and the rest for 6 speakers. my room is roughly 10x18, and i'll be buying a denon 3806 for a reciever. it doesn't matter to me what size/type of speakers i use (bookshelf, tower, etc.) i'd like advice on a few things: 1. is 25% of my budget too much to spend on a sub? 2. what would your recommendation be if i spend $1500 on my 6 speakers? 3. i'm planning on a 6.1 setup, but i don't think i can get one of my rear/side speakers lower than 7' off the ground. will this be a problem? any input would be appreciated. thanks.
