I don't know why anyone would expect data in a sub review. Very few
professional subwoofer reviews ever provide any data, yet we should expect a post by a newcomer in the 'beginners' section to provide data? What kind of data could you possibly expect here anyway? CEA-2010-A measurements? The response to this guy's review has been absurd. My only suggestion is that this post would have been more appropriate in the
'write your own reviews' section rather than the 'Beginners' section.
I don't necessarily expect data either as I usually don't include measurements in my reviews.
I don't know that I would exactly call these "professional" reviews either, but the measurements are useful. Data, you know like Data-bass? It is sort of their fault, and this is the sort of data I would look at too if looking at a serious sub. This won't tell you how it sounds, but it WILL tell you if it performs and if a sub's claims are optimistic or has a glaring fault, the data will usually indicate that quickly.
