Does anyone run front presence speakers? Do they real do anything for the over all sound? I have a Yamaha V2400 reciever and it has hook-ups for front presence speakers and I am wondering if it is anything worth looking into. The only real problem I see is that you can not run both the presence and the rear effects at the same time, and being I have a 6.1 (that will be 7.1) that is a problem. I am assuming the rear effect would do more for you then the presence speakers?
