Of course, I can only subjectively judge, since I do not have the means to measure the result - but my HE-500 (with FocusPads) sound much more realistic after their calibration.

I only read about it recently and it looks like quite a capable piece of software as well.

Of course there can be different opinions on what should be done such as whether we should be trying to fix frequency responses above 300Hz...<br /><br />I just have to note that Acourate does a great job and the basic technique works for me.

But, I do not think a "flat" target or measured response is at all desirable above the bass transition frequency. What is almost universally recommended is a smoothly downward sloping response with increasing frequency measured near the seating position. That is what is important for listeners.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-5602555313072153992016-06-03T10:18:12.732-07:002016-06-03T10:18:12.732-07:00I am currently reading into Sonarworks Reference 3...I am currently reading into Sonarworks Reference 3 HD, which should be more easy to use. I was told by support, the HD version can measure speakers up to 4m apart accurately and also is suited to include multiple subwoofers. Nevertheless, I had no chance to try it out so far, but I see they are making measurements on many(!) spots around a listening position, to enhance accuracy in a bigger area.Balduinhttps://www.blogger.com/profile/06780813865072444287noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-82261761809706484022016-06-02T01:21:36.561-07:002016-06-02T01:21:36.561-07:00I love what you write and your mission, but I don&...I love what you write and your mission, but I don't really endorse the use of convolution filters in the manner you are doing.<br /><br />By all means use it up to about 250-300 Hz, but above that you are causing problems.
