I've been eyeing these bad boys since before black friday and they have been unrelenting in coming down in price, that is... until today.
I decided to upgrade to these from my previous Z323 (which are great speakers), but the 623s give you just so much more. The bass response, jesus.
If you're more of a snobby audiophile you might be better off with the Klipsch Promedia 2.1s (supposedly they're the better version of these, with a less powerful bass response, from what I've read.) but my main use is watching movies and I listen to all sorts, from hip hop to film scores and to me they sound great. I rarely turn them over halfway as to not upset the neighbours, but that's usually more than enough.
I wouldn't call £120 a steal for these, but you'd be getting them for 20 quid cheaper than I did and I do not regret it at all.
