We are comparing Data-bass, audioholics to newspaper publication?
Data bass and audioholics backs their reviews with measurements, they rate quailty of a product by taking it apart and inspecting driver, amp, enclosure etc. All tested subwoofers/speakers are ran through a consistent measurement protocol.
That is not opinion. Nor similar to a general article from a newspaper. It's a review backed by researched measurements.
It's always easy to recommend what you own, especially if you satisfied. Also the user has spent enough time with their recommendation to provide real world feedback. At the same time it also leads to bias and writing off a potential better option for someone else.
OP, you have enough information here to make an informed buying decision.
