Now, I have to really come out and say something here. This product is described as a "budget" product. Well, if you own a mansion and want the best stuff you can get it probably is, but for the average Home Cinema enthusiast you really cannot go wrong with Mordaunt Short.
I had long had seperates for my Home Cinema system but I lacked a subwoofer so I invested in one of these. The guy in the shop described it as " a beast". I thought that was just nonsense sales talk, but sure enough this product blew me away. Using it for some cinema is one thing, but using it with high definition sound is something else entirely. This thing literally shakes the walls.
Like most good subwoofers the sound you get is not static. It can be regulated to your liking and so you can have just as much or just as little punch as you like, irrespective of what the volume of your system is otherwise set at.
I would perhaps go as far as to say that this is the best speaker I have bought to date and highly recommend this manufacturer. When I replace my satellites I will be going back to them.
