Has anyone used the Bravox 5.25 shielded driver at PE? I would like to attempt a DIY speaker project. I am a firm believer in tried and true designs to start with, but the price is pretty tempting. The response curve looks as good as any I have seen. I have completed one speaker building book, but I still feel a little clueless on the matter. I feel I can layout a basic crossover and handle a sealed or vented enclosure; however, handling issues like picking the in-phase crossover point and correcting for a tweeter that is more sensitive than the woofer still seems a bit past my understanding. Also, if i use a MTM design, does that change my crossover layout dramatically (other than impedance adjustments)? Is there any free or reasonably priced software to do this? I am also leaning toward a Vifa 3/4 shielded textile dome tweeter.
