I am wondering if it's worthwhile to upgrade my left and right main speakers or if I should wait until I can afford a sub.\n\nSo my setup is like this: Receiver is a Denon AVR X1500 running to Dayton B652 Airs with a C452 Air center channel. I also connected some old Optimus speakers that were destined for the trashcan but I figured they'd make okay surround speakers. So it's a 5 channel surround w\/ no sub. \n\n\nSo I was planning to save up 500$ or so for a sub but today I went down a bit of a rabbit hole with tower speakers and I'm wondering if Id get a noticeable improvement from a speaker upgrade. \n\nI'm not exactly unhappy with what I've got but I feel like it does a lot better for movie watching than it does for music. I figured a sub would solve my problems but then I don't want to get a kick-ass sub and discover that my little Daytons are still dragging me down.
