[QUOTE="Jeff Babcock, post: 22907, member: 46"] Re: 12v Eco project sound system I would suggest that by the time you eq the BFM boxes to a relatively linear response, you will have lost a good part of their claimed sensitivity advantages. Also IMHO the "piezo array" only sounds about as good as an ENTRY LEVEL compression driver, has a very high crossover point, has considerable potential for inconsistencies between piezos, has limited peak headroom, has jagged response particularly off axis, etc, etc. I'm also not a fan of the lengthy "U turn" curved MF horn extending to such high frequencies, as there is higher potential for interference as the freq rises. They might be fine for your needs, certainly you can build them very cheaply. But I do find that the performance claims sometimes are overstated, so want to ensure you have fairly realistic expectations of capabilities. Fitz frustrates me sometimes with comparisons, for example his comparing the DR300 to an EAW KF760, which is just completely ridiculous. [/QUOTE]
