Amp question?

If I put a celestion tube 10 speaker (30 watt) in my epiphone valve special amp (5 watts) will the speaker make it louder? I'm asking because the amp is already too loud, but I want to change the speaker as it is bad, but without making it louder.

only way that will get louder is if you get more watts in the amp .... speaker watts no matter.

nope. it won't get louder. you're ok.

no worries it won't make it louder, but 30 watts isn't loud
