I have the (even performance poorer predecessor) system a party thrown in a 50 square meter room and thanks to my active cooling ("40 diameter continuously directly let cm fan on full step back blow on the heat sink of the power amplifiers of the subwoofer") ran the Annex 9 hours continuously, with absolutely maximum set volume on the PC, at maximum volume on the system itself, with all software volume tweaks that could (override's MP3 when it allows the dynamics) I find and sonicated the full 50 square meters as four 1x1 m² disco boxes! I could hardly believe it myself, but I've never bought a product of such great quality, would not even sell at a price for the "Boose" my earplugs ...
200% recommendation to buy, you will never regret it guarantees. One of the few products that you buy in the course of life and has to smile even after a few years yet, if you look forward to once again about the quality and Langliebigkeit (and which one has not bought cheaply scrap determined long ago given up the ghost would), while wonderful music echoes through the room ;-)
