Speakers are subjective. You may like them better than the Klipsch, the B&Ws I've heard I wasn't impressed with (nor am I much of a fan of most Klipsch speakers altho I'd like to check out their latest RP series). I do have an RW12d sub, tho, and definitely better than that out there fwiw. The demands on an amp will be different, tho. Sounds like a decent price from the little I know about them, tho.
Keep in mind the speaker wattage ratings are pretty much meaningless, more important to focus on their sensitivity and impedance spec when it comes to amp choice.
