Purchased a set of these speakers recently from Bing Lee and I can honestly say they are the best sounding most powerful set of computer speakers I have ever owned.

I recommend these speakers without reservation to anyone wanting a high performance set of computer speakers at a reasonable price.

Totally amazed at the sound, volume and sheer power of these speakers

very happy with this product.. Great quality sound and even better value.

I've had these speakers for about 6 years now (may be previous model) and they are absolutely amazing. I paid a lot more than this for them though.

I ordered a set of Z623's from Bing Lee six days ago, to replace a 14-yr old Justa set of computer speakers which had succumbed to old age. To my surprise they arrived here in Adelaide three days later, courtesy of Australia Post. Very easy to install (all cables are supplied), they were soon pumping out fantastic sound with deep, rich bass at amazing volume -- and I haven't turned it anywhere near right up yet! (I believe in running speakers in for a few weeks before approaching max volume. And in any case, max vol would be TOO LOUD so close to my ears!)
At the price I paid ($99 + postage) they're an absolute bargain. I note that the price has just increased to $149, which is still not bad. Perhaps if you speak nicely to Bing Lee, they'll let you have them at the old price..... :)
Points to note:
1. These are designed to function as PC, TV or music/entertainment station speakers, and work well as such. They are not meant for audiophiles seeking the very best in sound reproduction. For those you pay a lot, lot more.
2. The sub-woofer is quite large (30cm (w) x 23.5cm (d) x 27cm (h), and is designed to go under the desk. This wasn't possible with my configuration, so it sits on the desk where it takes up quite a bit of real estate.
3, When listening to music vocals, if you turn the bass response down from the default position, sibilants (i.e. 's' sounds) become quite harsh. Using the default position or higher, everything's fine.
4. The units seem well-built using high-quality materials.
5. These speakers are *great* for watching DVD and Blu-ray movies on the computer!
6. I would definitely recommend them to a friend.

No issues with my purchase, fast delivery and accurate tracking, Speakers live up to all the positive reviews.

Just received these speakers and they are superb for the money. Don't really look much but performance is excellent. Packed very well for transit only regret is missing out on the extra 20% discount from Ebay orders. Will check all options in future.
