Gallo Reference 3.1 in a 11x14x10 room. Plenty of juice in my Sig 30.2 to give me realistic levels on most music. And even though the Gallo's are only 88db eff., the little Red Wine TOTALLY kicks ass on the bottom end, tightest, fullest and most tuneful bass I've ever heard. The Gallo's are a very easy load, very little X-over. Beats out my all time fav in that department ,the Vandersteen Model 5. Doesn't go as low, mind you but listening to an upright bass on this combo....... pure magic.
