on our loudspeakers.
Unfortunately, not all +/- 3db frequency response specifications you'll
read are measured under the same conditions.(Meaning, the measurements
from one loudspeaker company may have been conducted under one set of
conditions, while the measurements from another company may have been
taken under a completely different set of conditions.)
There are no industry standards that all loudspeakers companies follow.
Specifically, where do you place the measuring microphone (on the floor,
or suspended directly in front of the speaker - and at what distance).
Where do you place the speaker, on a stand or on the floor.Do you take
room reflections into consideration?If you don't, it's difficult to
accurately measure a bipolar speaker.......
So, be careful when you compare specs from one company to another.If
at all possible, I'd recommend auditioning our loudspeakers (and any
others that you're considering) and trusting your ears.
