And some have overheated them...
How about asking what somebody already uses, how loud they play, who they play to, what kind of music they play? You know, things that MIGHT factor into the correct response?
Tell us more, sunny, and you'll get more than a guess. One thing that's a universal, though. A 12" is always heavier than a 10"
And convenience is in the eye of the beholder. I don't find my G70 inconvenient
The rule of thumb is, a 12" from the same manufacturer to a 10" (and an 8"
) will be louder, deeper and heavier. Whether you NEED that volume and depth (and weight) is for you to decide...
