The 5 speakers will be shelf mounted and the sub will be on the floor. I will be building the shelves so I can customize the speaker placement. My budget for the next several years for this 5.1 is < $500, so I will be buying these speakers/sub at the same time. I am wanting 5 speakers and sub for home theater that play good and loud, and the louder the better. The 5 BIC speakers and Parts Express sub look like the best choice for buying new. But I really would like to buy used or discounted so I can get a better sub. Are there any other speakers/sub I should consider? Thank you all for helping me with this.
