It depends. Live in an apartment and are reasonable about levels. Probably. I just modeled my current Seas speakers, and the SB and CSS I may use for my next build, determined what power would exceed X-Max, and yea, it should handle what I do most of the time. I ran a 40W Creek for a week while I was refurbing my 60W MOSFET and it did OK. Now, if you expect to do live full symphony or just have to crank up AC-DC, then no unless the mains were Klipshorns. If your mains are reasonably efficient, they it just might.
