I've pretty much always gone with the usual regarding speaker settings but the last week or so, I've been adjusting things and changing various settings. I've always set everything to small but have changed most of my speakers to large for the last week and watched some new and some older movies just to see how much, if any, difference it would make. I'll have to say, the difference was quite dramatic. Both my GF and I noted more dramatic bass and low end and more in your face power. My system is comprised of: RXV-1 Yam receiver Acurus 200x3 driving mains and center JBL L100 mains Veritas 2.0C center Energy RVSS surrounds JBL Sat 2 as double rear centers SVS 20-39pci All except the rear center set to large and the LFE set to BOTH has made a dramatic difference. Tonight we re-screen LOTR-FOTR in preparation for LOTR-TTT. We were both stunned at how powerful this was in all the dramatic sequences. Next week I hope to have my 2.2 Veritas hooked up as mains. Received them last week but one was damaged (thank you UPS) and is back at the dealer for repairs. So far, the Veritas 2.0C has excellent sound and is very accurate. Plus, those Veritas are really a nice looking speaker set.
