Crutchfield now shows these in stock. Alpine still hasn't posted the T/S parameters on their website, so I called them on the phone and they were willing to fax it to me.
Parameters are very similar to last year's model (SWX-1242D). Motor strength is increased slightly (more copper in the coil according to Alpine), and mechanical mass (Mms) is reduced. As such, SPL efficiency is increased by ~ 1.5dB and box volume requirements are slightly reduced. All in all, the 2006 and 2007 models should perform similarly, considering the specs are so similar and they model about the same.
Sorry I don't have the info for the 10" version, however the difference(s) should be on par with what they changed on the 12".
Here are the specs: (Items not listed in bold were auto-calculated using the other parameters)
Qes .64
Qms 7.48
Qts .59
Fs 29Hz
Vas 38L
Mms 314.6g
Cms .0957mm/N
Re 7.2 ohm
BL 25.39648 Tm
Le 3.25 mH
Sd 529 cm^2
Xmax 19.0mm
Pe 1000 watts RMS
SPL 83.64 dB
Dual 4-ohm VC
Anyways, I'm planning on ordering a pair next weekend from a local dealer. Has anyone else been waiting on these to be released?
