edit: lots of tech blabla on top, but do you have any personal experience with this set of speakers? My brother has these and neighbours will start complaining before the speakers struggle.
I have. We had the Z-2300s in my old school, and the Z-5500 in my current one. I haven't gotten a chance to do any real benchmarks on them other than running sweeps and listening.
And you need to understand that there's more to this than power. Power is cheap, I can design a half-decent 2x200W amplifier for 30€ in a night, using the same kind of cheap chips that Logitech uses. The hard part is to make that power into sound, something that Logitech fails utterly at. Look at my speakers, for example. They're twice as big as the subwoofer of the Z-5500, with 10" drivers that feature more excursion than said Logitech driver. Yet, they're rated at 50W each, where the Z-5500 sub is rated at 180. That's because my speakers are a lot more efficient at making sound out of electricity than the Logitech.
Now, if my drivers, which aren't any top-end things by far, can make as much sound at roughly 40W as the Logitech can make out of 180, that's quite some excess heat created in the Logitech driver. Now, there's a whole science behind this, but in short, a driver gets less efficient the hotter it gets. The Logitech, producing almost five times more heat, will warm up much faster than mine, resulting in
even less efficiency, and even less sound. Driving it at that level for long will make the adhesive holding the coil together melt, and break the driver beyond repair.
The satellites don't have a high-pass filter on them, making them output low frequencies too, which, being one-way drivers, results in distortion in the higher frequencies which they should be covering. Being cheap one-wayers also gives them some serious issues in very high frequencies. Neither the Z-5500 or Z-2300 can produce much sound at all above 16kHz.
