They ALMOST have a point though
In many cases, as everyone here knows, a garbage product (white van speakers for example) will be rated at 20-20 (with no mention of curve or allowable variance).
In those specific cases, the numbers are irrelevant and are just misleading marketing, which BOSE knows all about.
When it comes to Axiom, Advent, RBH, Paradigm, etc. They are all high end, quality products that are accurately designed and measured. When RBH says 45 to 20 +-3dB, they mean it and can prove it.
Just because FISHER says 20-20 for a $299.00 speaker, it means nothing in the real world.
I promise you the better built speaker will reach lower and more accurately every time, regardless of the higher, advertised (more realistic) low frequency response.
When it comes to room placement and imaging, BOSE is the pickiest speaker on the market today. They SHOULD be focused on that issue as it effects their product more than others, but to dismiss it as a reason for not advertising frequency reposnses is pathetic.
BOSE should offer a frequency response graph along with blueprints so you can design an identical room to achieve it in, they are effected by such issues a lot more than anyone else is.
BOSE knows this too, of course, but they focus on dismissing and making those stats are irrelevant. They compare themselves to a low end market segment and say, "Homey don't play that game".
But Homey don' t play with the big kids either, Homey only plays alone, that way he never loses.
