You read that right. I didn't even have a chance to play with it. I had a 200L cabinet made for it, and during the weekend decided to install it. The minute I fired it up, I just knew something was wrong - at anything louder than "barely audible", the sub sounds as if its heart was being ripped out: noise was coming from the tinsel leads, from the vented pole, everywhere! It was as if the coils were slapping the driver cone, and it sounded loud. REALLY loud. I rotated the driver, and indeed, the noise was gone on certain positions. When downfiring and upfiring, it was noisy. When firing sideways, there was one position where it was dead silent - but it was in a very odd position, and inclined in a diagonal, to boot! A friend of mine told me it was probably the voice coils out of alignment with the magnet piece (I really don't know whether he is right or not). Aw, well. I can't return the damn thing because I live in Mexico, and S/H would cost far more than what the subwoofer price was. And I can't replace it, because I'd be risking getting another defective sub. I'll have to build something else with different drivers. So long, Adire Audio. Hello, Cerwin-Vega!
