Why does it matter (honest question), if the HP (or any speaker system), produces sound that is louder then most people need, and the HP seems to fit that category, then what does it matter what the wattage is?
It doesn’t, not really. So many things combine to make an audio system work.
There’s only one important factor, whether it sounds good to you or not.
It’s why there are so many different (quality) HiFi amplifier and speaker makers, we don’t all hear the same thing.
But wattage is a damn near meaningless way to try and compare one system to another. Something anyone who’s serious about HiFi or Home Cinema will quickly learn. It’s there, by and large as a boasting factor and for people who just want to pick the “most powerful” one they can get.
If wattage were the be all and end all then a cheap 100 bucks sound-bar with 500W of output would sound better than a several thousand bucks setup of, for instance, Arcam and Monitor Audio with 100W yes? No, of course not.
What’s more important is the ability to generate, well pure clean power for want of a better description.
You will, if you’re a HiFi nut come across stories, or know of someone who’s willing to spend many thousands on a simple 20W Valve Amp. Why? Because the good ones can blow the arse off of some amps with 5 or 10 times the wattage.
It’s an incredibly complex field, one that’s definitely worth looking into if you’re interested. There’s plenty of online resources and books that will explain the finer details. But the one overriding factor is power and clean controlled sound, isn’t directly attributable to wattage.
Oh, if you’re curious on what one way to help tell, if you’re in a shop for instance, and just can’t decide between a couple of amps after considering all of your options (and I do just mean traditional ones here, not valve amps) and you just can’t come to a conclusion, pick the heavier one.
The array of components and the quality of them, required to make a good, powerful amp end up making it heavy.
I’d definitely not suggest that as your only way of making a decision and it’s anything but scientific. But it’s something I (and friends and many a journalist) have noticed in my 20 odd years of HiFi, the better sounding ones often seem to be the heavier ones, go figure.
