I had a pair, they're the ones with a passive bass radiator.
I only used mine for a couple of months before selling as a cheap pair of Mission 752's came up locally that I couldn't turn down but the Wharfedales were ok considering they were entry level model. Pretty good bass extension and quite a revealing tweeter. My wife even liked the trapezoidal shape of the cabinet too so they got a thumbs up from her.
Bottom line is they're ok but only if the price is right as some properly good second hand floorstanders can be had starting at around £150, I think I paid around £40 for mine but sold them a couple of months later for £60
