Wouldn't that be impossible to tell unless you actually did give them the proper box, appropriate power, and used them in the same vehicle....... and you should test them all with the same equipment too. Actually, somebody should try that. Would cost a lot though.
that's why I am asking all with experience..and I'm hoping for unbiased answers. Seems to me like all those who are capable of answering...are afraid to answer or they simply "don't care" even though most or all do care.
If you were to put all the "superwoofers" together as far as the proper enclosure and power, they'd still perform differently in the same vehicle due to their frequency characteristics and vehicle cabin gain. Furthermore, a fair comparison would be anechoic, and if you were to put all the woofers beside each other in a typical enclosure, they'd be so close to each other in SPL that it really wouldn't be worth spending the money to compare them. One sub really wouldn't blow out the other, although it may show a little more SPL (within 1db of difference). Once you get into this type of comparison with these types of subs, you really should start choosing on what your ears prefer.
RE MT - Happy now?? Is that an answer you're looking for? In all seriousness, Jon's right, it is what your ears like. There is no loudest sub, but the MT is pretty bada$$, that is if u properly power it.
Yeah, I've seen that. The only thing I don't get is it only has 2.5 inches of excursion. On the site their not sure if that is one way or peak to peak, but still, even one way; isn't that small for a 300 pound sub? I meen some 12's and 15's can have 1 - 2 inches peak to peak, can't they? I would think something with a diameter of 3 feet would be able to move a ton, like 8 inches or so. Maybe I'm missing something though. I also wonder how loud the 36" Audiobahn sub is. Even though Audiobahn is crap, still, it's as big as the mtx. I think it costs a lot more than 6k too.
