...especially how someone could examine something without seeing or testing
it.
This question should be directed to Ralph Karsten.
8 ohm speaker hooked up to 4 ohm post ?
Blindjim, your question is in reference to Ralph's comment to me about the impedance curve of the Sonata III, yes? For full explanation of how he came to his conclusion about what he suspects is the Sonata III's minimum impedance, he would need to chime in here. He did not describe to me the method of how he determined this, and therefore I cannot answer your question. Ralph shared only his opinion with me based on what he saw on the Silverline website about the speaker's design, and what he knew already of the drivers utilized. Apparently, he is familiar with Silverline speakers, and has recommended them in the past for use with his OTL amplifiers, although Silverline Audio is no longer on his speaker manufacturer list. I believe he still recommends certain Silverline models due to their more benign impedance curves than the Sonata III, but I do not know which models. I have emailed Ralph with a link to this thread. Perhaps, he'll share how he came to his conclusion. Hope that helps. |
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. |
