I was hoping to hear solid differences, like I heard the 1700 has different cone material than 1280. It's like he found different vague descriptives of them or experience of each one but he probably wouldn't say the rest were void of the same for the most part.
I recieved the 1280 damaged on arrival from Amazon and sent them back for a refund and got the 1700. It's a lovely bit of kit for the money, I've got them as a set of desktop speakers but feel they could do with more oomph.
What was the point of this? I'm glad I skipped to the end to hear the reviewer's final opinion ...which never came. You can't just ask the audience what they think!
