If the measured speaker's response will result correct (flat) you may think that I have some hearing problems... But I have heard other prestigious speakers that sound great to me (for example B&W 802D). I think that nonlinear effects in the response to transients will make a great difference between different speakers, a difference that could be not detected with a simple frequency response test.
Anyway I will try to arrange for a serious frequency response test...
I meant that different speaker manufacturers design their speakers with different Frequency Response patterns.
Many speakers, when placed in an average sized room with little to no acoustic treatment produce a descending FR, so the lowest octaves are typically anywhere from 10db to 20db higher/louder than the highest octaves/frequencies.
In addition, depending on the type of tweeter used, a graph of the speaker's FR may also show a greater downward curve above 12kHz-16kHz, in which case, 16kHz may be more than 20db lower than 30Hz.
Legacy Audio speakers tend to produce a flatter frequency response all the way out to 20kHz, so the highest frequencies are almost as high in measured db as the lowest frequencies.
If you're used to a descending FR, you might find the Legacy Audio speakers to be too 'bright'.
The speakers I previously had produced a descending response with a measured 15db drop in my room from 30Hz to 20kHz. I prefer this response for a lot of music.
The Focus SEs that I have are great for movies and HT though, where they're calibrated for a flat in-room response (which happens to be very close to their natural non-EQ'ed in-room FR) to reproduce THX Reference.
