This speaker was recommended by our electrician who said that, despite it being one of the most expensive on the market, it would be worth the money and he was definitely right - both the volume and quality of sound are incredible for a single speaker with no sub etc. and it can be heard throughout the house (not what my wife wanted but never mind lol!) when on top volume.
I listen to a lot of electronic music (house, techno etc.) which has a lot of bass and often comes across very poorly on even high-end smaller speakers but not with this one - would 100% recommend although definitely hunt around for the best price (I saved well over £200 buying it here vs. some other websites).
