I just got my second pair of NHT 1.5s today to complete my 7.1 system. If you don't know these speakers, its just a basic, direct radiating two way bookshelf speaker (not a dipole or bipolar) I have the existing rears mounted on 24" stands, for approximate ear level when seated. That is what I was planning to do for the second set as well. However, all the diagrams in the receiver's (Denon 3802) manual show all the rear speakers mounted high up on walls, pointing down. I was under the impression that this was the right way to do it with dipole speakers, but not with direct radiators. I won't be mounting on walls, but I am wondering if I shouldn't get stands atleast 36" so as to raise the speakers up, or if I should stick with the 24" height, which puts the tweeter at about ear level. what do you guys advise?
