Well, I drove a pair of pair of Audiophile 4's at a New England Bottlehead meet (two meets ago) with a 6v6 pushpull amp (10 watts?) on the TAD 1602's following an active xo, and a a pair of 300B amps (9w/ch) driving the passive xo JBL mids and TAD 2001 tweets.The Bots were leaning toward arena rock on vinyl at that point, and in a good sized living room/kitchen area it was damned convincing. (The JBL 2123 mid was a bit prominent, and Bill M. found the bass/cab a bit "thrummy", but it ROCKED just fine.)
