They are pretty good - the ones with kevlar woofers. Another one you might want to consider is the www.ascendacoustics.com They got raving reviews and are reasonably priced - since they sell direct, cutting out the middleman, they can offer more quality for the buck.
You can try it for 30 days and return them.
Thank you James. I have never heard of these speakers, or heard them, but they are certainly very reasonably priced. Have you listened to them?
the wharfedales are very nice speakers but they are power hungry and not very efficient. You need a more robust receiver or power amp to drive them, driven by the right equipment they are hard to beat.
Now the ascend acoustics are a totally different matter, they have a very nice staging quality and should match well with your HK. cheers
