The EV ELX115Ps sound great! You won't need to worry about them being loose. The twelves will have a more accurate off axis response but won't be as loud.Ok! Than you for your infos! I've already read that 15" might be good for some reasons but less tight than 12"... thats why I am a bit in a dilema between 12 and 15.... -_- And I still am haha!
