Right George, the Tympani bass and midbass is really something: very "percussive", taut. They do a drumset like nothing else I’ve heard. An aptly named loudspeaker! ;-) They "go" lower than do many cone woofers (the two bass panels compromise a considerable square footage), but to get the most bass out of them they need to be braced. Grant VanderMye makes a great stand for the Tympani, but it'll cost ya. A cheap way to do it is run a wood rod from the back of the bass panels to the wall behind them. Not pretty, but effective.
