Elipsa's vs. Extrema's is a very interesting trade. If you need a speaker with more ability in the bottom end, I would go with the Elipsa's. However, not at any kind of uppricing.
OTOH,some of this would depend on the condition of your Extrema's.
You would be trading a speaker with a better mid and high freq driver for a speaker with a more modern design and as previously stated a little more bottom end drive.
Like Donjr asked, what is it about the Extrema's that makes you so eager to trade....IMHO, they are one of the best speakers that SF made.
