I have a new HT system with a Denon 3802. I'm not happy with the sound field from the side Klipsh Quintets when in 6.1 surround mode. I was thinking of buying another pair of Quintets and adding them to the side surround for a total of 4 speaker (any comment on this?). I already have surround backs. The Denon has the ability to do this sending half the power to each set, I believe. But with the investment in Two sets of surround speaker would it be better to spend the money on one pair of bipolar speakers instead? If bipolar is better what can I get for a $200 budget (my cost for 2 pair of Klipsh). This system is mainly used for movies.
