Bat 32SSE up top.
I like the Legacy's. They like to be played loud.I had infinity IRS Epsilons powered by 2 4Bst. One Emin went and I couldn't get a replacement so I parted out the Infinity's. The Legacy are a more refined version of the Infinity's. The bass is definitely tighter with the Legacy's and the Infinity's even had an outboard servo control unit. The highs and midrange also seem smoother but that could be the 7BSsT/2. Prior to the Infinitys I had the Thiel 3.6.
The Pangea's not sure but the Bit 20 did make a noticeable difference.
