pHAT BEAT with pi4

hi
i bought a pHAT BEAT, plugged it to my pi4. It is working but the sound is not good.
My speaker is : 4 Ohms , 3 Watts

I wonder if it is possible to plug more another powerfull speaker maybe 5 Watts ?

Thanks
Regards

I don’t think the speaker watts is going to make a big difference? Not as far as quality is concerned. Loudness yes, quality, not so much.
You can run it stereo, Its how I have mine setup and I’m very happy with my sound. I’m no where near full volume, maybe half way?

Haven’t used mine in months and months , oops ,mine isn’t on my pi4 , Ignore !
