Archaea Posted November 20, 2015 Report Share Posted November 20, 2015 I have a suspicion this might be in the interest of showing the 212HT/HTR - etc aren't lacking in 'mid-bass' as is a occasional discussion on the JTR thread. With that much headroom, you can EQ them to any amount of midbass you desire in your own personal setup. Check out them compared to the LMS-5400 in a sealed enclosure for instance. Above 55Hz the 212HTR start to significantly have more bass available than arguably the best 18" subwoofer sealed. They have zounds of headroom actually...

lowerFE Posted November 21, 2015 Report Share Posted November 21, 2015 How come the 212's are rolling off at 200Hz? Last time I checked they go up to 24KHz? Even if you disabled the tweeter shouldn't the response roll off closer at 300Hz to be -6dB at the crossover point of 360Hz? Link to comment Share on other sites More sharing options...
tuxedocivic Posted November 21, 2015 Report Share Posted November 21, 2015 I'm not sure how Ricci feels about this, but I wouldn't consider the data above about 200hz very useful in a GP measurement. Link to comment Share on other sites More sharing options...

Why do you think the data above 200 Hz not useful in a GP measurement? Link to comment Share on other sites More sharing options...
tuxedocivic Posted November 22, 2015 Report Share Posted November 22, 2015 IME it doesn't capture the response of the speaker very accurately. Especially at very high frequencies where the wavelengths are relavent to the distance between the mic and the ground (1", top octave). They don't seem to capture the baffle step response very well and the speaker needs to be stood up and angled down towards the microphone carefully. If you're outside and measuring, why not just throw it on a ladder and get a more anechoic representation. That's not to say above 200hz throw the data out. But if the speaker was laying on the ground or not angled towards the mic or something (since Ricci was focused on bass) then the result isn't surprising.

Ricci Posted November 22, 2015 Author Report Share Posted November 22, 2015 JTR specs are for 1m fullspace. The measurements here were taken at 1m halfspace. That's a 6dB difference due to the methodology. Full range measurements above the bass range do need to have different considerations made for the setup. The low pass filter was in line.

shadyJ Posted November 23, 2015 Report Share Posted November 23, 2015 Hey Josh why no comments on that beastly Rockford Fosgate driver? I would be interested in what you have to say about that monster. Link to comment Share on other sites More sharing options...
Ricci Posted November 23, 2015 Author Report Share Posted November 23, 2015 Ran out of time...Had to pack and drive to NC for the gtg and just got back home. I'll get it eventually. Link to comment Share on other sites More sharing options...
