Regarding the published frequency specs of the new models, Spendor has simply adopted the tactic of other manufacturers by publishing the audible limits instead of the anechoic chamber specs as they did in the past. The SP1/2R2 model also has useful bass in the 30Hz range. I imagine they realized they were losing sales because many don’t understand the meaning of "anechoic."
The SP100s are 3-way but they still retain the midrange magic and tone for which Spendor is known. If I had the means, I think I’d probably risk trading my SP2/3R2s for the new 1/2 without an audition. It looks as though they simply scaled down the Classic 100s to create the new 1/2.
I think the biggest difference will result from the cone material, which they borrowed from the D series. I think this accounts for the increase in sensitivity, which probably results in faster transients. It’s a similar material to that used in the Stirling Broadcast LS3/6, a very agile speaker.
