How is the effect of Bose L1 family karaoke? Specifically?

Needless to say, of course it is good, it is a small performance equipment.

Of course, you need something else. There is a limiter in L1, but there is no reverb or exciter. You may need one to make your voice sound better.

Also, L1 needs to be used with a subwoofer. It is best to use one stick and two boxes for the best effect.

Finally, this thing is very powerful, so be careful about complaints from neighbors.
