OK- here's how I did it: I googled the Sonata III and did a lot of reading and combined that with experiences our customers had with the speakers.
I suspect that the break-in discussion in this thread is very real. When the woofer is new and the suspension is stiff, it will resist efforts to move is to a greater degree than after the suspension has loosened up. I have experienced this before on the Snell B, which needed to be broken in for several weeks on transistor gear before tubes would sound right/could be used on them (no bass otherwise).
I suspect this phenomena is occurring with the Sonata III as well. The reason we took them off our very abbreviated list is that a customer sold his amps when they did not drive his Silverlines. In the old days any of the Silverlines were easily driven by any of our amps (in fact we showed with Alan at CES), but now-days it seems like the Silverlines are being built for transistors, which dominate the market. That way you can sell more speakers, although IMO/IME they will never sound as good.
