Sheep-
I completely respect your perspective and your experience. I am a student of objective data myself, after all, I am an engineer(in fact, licensed).
That said, there is something to be said for those who have a lengthy audio experience. I've been putting together systems since I was 17, and that was 15 years ago. I've heard many, many, very exemplary systems, both car and home. During that time I'll admit I haven't always had the instrumentation to document exactly what I've heard. In fact I never have. But I am confident that I know what sounds good and what does not. I don't claim to hear difference between speaker wire, and I don't think RCA quality makes a damn difference.
That said, I do not intend to say that my opinion rivals those who test and document performance of current technology(on a level basis, that is very very, valuable.). But I will say that I can use fairly qualitative descriptions to describe what I do hear. I don't split hairs, the differences I mention would be easily discernible by any enthusiast(and any average Joe with a little instruction). I.e, I don't use esoteric language like "warm". I can hardly see how language such as "tight" is esoteric in the subwoofer world..
My current system is many times better than yours(no offense intended), and I have heard many better. It may seem trite when I say that one sub is tighter than another, but rest assured that if I do so I am comparing two components with relatively small differences. I know what money can buy, and bashing cheaper equipment just isn't my deal. In the mid-fi arena, it is the small differences that count. You can't always rely on a simple review of one item to be the end all.
I suppose my thesis would say that objective performance data is no doubt king. But if you put a couple fairly equal items together on a level platform with an experienced listener, there is no reason to poo-poo a couple of simple qualitative descriptions.
Sponging what I'm spilling?
