Will be waiting for your response next week
Well, the PE Air Jordans arrived today. I was very interested to see whether PE had really fixed the woofer breakup by building more inductance into the woofer voice coil, as another reviewer (No Audiophile) had claimed on the link zieglj01 had posted. And, of course, I wanted to see how the new amt tweet sounded and measured. The results were a little frustrating. First, there has been no change to the woofer. It still has a big honking peak at 3900 Hz. Since there's no crossover on the woofer, there's nothing to suppress the ringing breakup mode. As for the new mini AMT tweets--will the real new tweet please stand up? My pairs didn't match at all well. When mated with the woofer, one sample had a huge dip at 5 kHz, which didn't really sort of flatten out until 7 kHz, above which the response was a little ragged but acceptable. The second sample filled in much better, although it was also pretty bumpy. I hate it when that happens, because now I don't know which sample is more representative, and I can't develop a revised crossover that will perform consistently across samples. Despite all this, does the AMT version sound better than the original dome version? A little. The AMT, or at least one of the AMT's, has a bit more output down low, and that tends to distract attention from the woofer peak. But my corrected version of the original sounds much better than either of the stock versions, so I'll probably still with a mod of the original. There's not much bass coming out of the sealed woofer, but it sounds a lot more balanced with a real low pass crossover that provides some baffle step correction. All that said, I suspect a lot of people will be very happy with the new stock AMT version given the price. It's voiced bright, which is exacerbated by the woofer peak, but it doesn't honk at you and sounds pretty darn good on simple program material.
