Sorry for the delay. Some family stuff going on.
I looked at the link you sent me, and if you want my opinion, unless they sound really good (which I can’t tell from the pics/features, but seriously doubt) I personally would never buy such a set. There is all kinds of stuff you don’t need , but DO pay for (money that didn’t go in to better drivers or amps). I think they look sheepishly amateuristic, but that is just my personal opinion.
Be aware that there is no power in the satellites (that I can see), you’ll always need the sub ( which houses the amp). If the main amp blows, you are left soundless. Two true active speakers would offer you redundancy if one blows, you still have the other one going. It has happened to me once and I was sooooo happy I could just play on.
I stick with my earlier advice, get some 10″ PA speakers like the Behringer EuroLive B210D with digital (built in) amp, which are small enough to use while practicing and have enough power for small house/birthday parties. You can always add a sub later if you want the extra uhmpfff (and the pleasure of fitting the thing in your car and hauling it around :-)).
They come in at about 144 euro each, 290 for the set. That boils down to 240 pounds or less? Leaves you money to get some decent speaker stands (it is a good investment,get K&M ones, they’ll outlive you) and perhaps some cables.
If you are lucky enough having to play a bigger gig, rent bigger and better.
Just my two cents. Good luck with your choice!
