@icedquinn 400W is bullshit. That's a PA amp power output, not a small speaker lol 15W sounds normal for a small speaker (yes it is loud enough).

How about wall-mounting? There are various brackets you could buy that'll fit a speaker in them. If the speakers lack screw holes for mounting, then two-sided tape will do. Small speakers weight almost nothing so mounting them on walls is pretty easy.

Most active speakers come with a screw hole on the bottom for "tripod" style mounting too.

It's hard to give any actual advice, since I have no idea how much space you have and what sort of height etc you want to have. At least wall-mounting would only require wall space, but of course it also requires the permission to drill holes.
