... It's more about what the product can do in one's system that matters...
From a manufacturers point of view, I would think it is about who they are selling to. There are other things than absolute output or performance to consider when one of the decision makers is not an audiopile.
This is true ... and often true even for an Audiophile. We all have criteria which is important to us. For example, the EP-500 is about half the size of the XS30-SE.
To some, this is a huge deal. For example, the EP-500 might be better a comparison to some JL Audio sealed subs, in terms of size and performance.
I could be wrong about this, but it seems the conventional wisdom is Axiom subwoofers are more often matched in an Axiom system while companies like PSA are more geared to someone looking for the most "SPL from 20 to 80 Hz" for the buck buyer.
One thing I have noticed about Axiom buyers - one rarely sees the Axiom owner disparaging other company's products.
