Heard only the towers before, they are.... meh. The center speaker being so small is kinda of a downer tbh - it's the most important speaker yet in this package, it's by far the worst speaker. 

I suggest you get either ELAC or QA instead. Don't have to buy every speaker at once. Just put all your money into the L/R and Center speaker first, then the sub then surrounds can be whatever. All surrounds need to be are they can play loud without crapping itself - unless you want to squeeze out that last 10% of soundstage immersiveness for an obscene amount of money.
