Just to help give people some sense of the value you are getting with these speakers, I would ask you this question.
Let's say you have a choice of say 2 speakers.
One is older, sells for slightly more, has just 2 drivers, the larger of which is tiny, and has a Sensitivity 9dB lower, which is like comparing a Corrolla to an F1 car, OR
The 'cheaper' speaker, has the highest sensitivity one can buy in a non-horn speaker of 95dB, has 5 different drivers to more effectively cover the frequency ranges and reduce 'holes', including 2x12" woofers, and would no doubt be equally well made as the more expensive speaker. Of course quantity doesn't trump quality, but when you have both...OMG!
The choice is embarassingly easy. Put the 2 side-by-side and run the full set of speaker tests using something like this:

And I'm confident the outcome would be completely obvious.
Something you will almost NEVER see on an official review site, is QUANTIFIED measurements.
Many manufactuers would never allow it, because it will show the warts and all of their utterly poor speaker performance. Sadly, it is generally just too complex to arrange for most speakers.
I would argue that the standardised information MUST be supplied to potential buyers as part of consumer law. This would prevent the OBSCENE rip-off that is no doubt a plague in itself in the industry. We have already seen this with reviews of many name brands being tested on www.audiosciencereview.com.
