What the Polk Audio XT60 does well: A budget tower with a woofer and two passive radiators that gives surprisingly deep bass for the price. Watch for: Bass alignment Q (lfq 0.96) is an unusually high, underdamped figure for a tower speaker, consistent with owner reports of a slightly loose, boomy low end at higher volumes.
