Those results show that the HM801 is using a sharp roll-off output filter. The slower roll-off is either due to an additional filter, possibly internal EQ, or due to NOS.   Gibbs phenomenon is roughly as bad as other...

Some low resolution applets exist on the web to do this. There is some variability in the results, but that's the nature of what you're measuring - perceived loudness. Generally its pretty accurate though.   By the way...

There is no direct measurement for this. The closest is probably intermodulation distortion. Possibly also spectral decay graphs.

If you don't believe a flat, centralised driver can give a 3D SS, you should try one of the true HRTF processors like Smyth. You'll quickly change your mind.   Angling the drivers, increasing the enclosure size,...

That's true, but my god I hope nobody is using the K1000 to listen to music which is so compressed

udauda, those charts refer to average sound pressure level, not peak. The calculation of 99dB SPL is the maximum SPL you can expect from that amp/can combo. In properly mastered music, the peak SPL can be more than 20db higher than the...
