I can vouch for the HK rig also. One of our club-members has the 600-watt version (300w bass bin and 2x150w satellite tops). It's surprisingly powerful for such a small rig and the floor-standing bass bin gives a nice round sound. Don't be put off by the small pole-mounted satellites - they're loud, crisp and punchy. The only drawback (apart from the need to buy a seperate mixer as TJ mentioned) is that you also need Arnold Schwartzenegger standing by, or a small crane, to load the bass bin into/out of your car - weighs lots!
