Should I chose the 10 or 12" brahma. I think the 12" would be deeper but the 10" would save space. Are they sq or spl speakers. Also would a MTX 1000d amp be enough to push them. With all that said how far away would you be able to hear this speaker. Everyone on this website is talking about them. I have never heard of them until now. Also can you tell me some more information about them.
