Hmmm...You use a low watt SET to listen mainly to classic rock? Well, I guess a Zu Essence may be your best bet. 10.3 inch woofer, 97 db sensitivity. Some folks are happy with the Tektons, also with a large driver and sensitive. I'm loving my Omega MaxHemp V2s, but it has an 8 inch driver which may not be enough for you to rock out with in that size room. As a former Essence owner I will say hands down that the Omega is a much more organic and natural sounding speaker than the Zus but our listening tastes differ as I listen mainly to jazz and classical. Just a thought: if you consider changing your amp, your speaker options will open up IMHO.
