Art Dudley reviewed the Gradient Helsinki 1.5 in our August issue. The speaker combines almost-conventional tweeter and midrange with a sideways-firing, dipole woofer. Room set-up is critical with these speakers. This is where they ended up in my own listening room, against the sidewall, and toed-in at almost 45 degrees, for a follow-up to appear in the November 2010 issue.
