I am looking to make a big upgrade in speakers and I was wondering if the Piano G2 is too small for my 18' x 30' room. I have a Bel Canto Black ACI 600 integrated amp, 300 watts/ch 8 ohms, 600 watts/ch 4 ohms. I listen at levels of 70-80 dBs at most but a lot of the music I listen to has significant low bass. On the other end of the frequency spectrum some people opine that Tidals (and Vimbergs) can be a bit too prominent in the upper midrange and treble. I prefer a full-bodied sound with a wall to wall sound stage.
