You should of posted in the Audio section. But still, i will help.
Here, these speakers are just subwoofers, and im pretty sure there loud.
However, they are good quality, but you could do better for 50 dollars, but you just want loud and bass, and you wont beat these.
From a technical point, the bass is gona suck if your some kind of audiophile, but by your description, your not. Therefor they'll be perfect
