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...

Davide,

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.

So you mean that a flat response speaker (like your Focus SEs) is more suitable for movies and HT rather than music ?

If yes, that could be the reason why I feel the problem. I could easily ask the dealer for a change, but only if I will get another Legacy speaker: what about the Calssic HD or the Signature SE ?
Otherwise I will have to sell them and look for another brand: in that case I would appreciate any suggestion from you, staying on the quality level of Legacy.

Thnx

It's not that the Focus SE's flatter FR make them better for HT than music per se, but calibrating for THX Reference for HT produces a flat response, so a speaker with a natively flat in-room response (and higher sensitivity and power handling) make it a good option.

When it comes to music on the other hand, some listeners prefer a tilted/descending FR and others prefer a flatter FR so it's more of a personal preference (I tend to prefer a descending/tilted response for music).
