Beautiful stuff there, Ilkka! Impressed with your charts! With more like minded people doing them charts, we could probably have the world's most comprehensive collection of demo material. Keep them coming, Ilkka! :emoji_thumbsup: :emoji_thumbsup:
I will be doing one for Resident Evil 2, AVP, incredibles and sky captain. It will take some time as I foresee myself a bit tied up for the next 4 weeks, but will not dissappoint. Stay tuned.
SVS's port tuning is actually a great feature, despite it cutting SPL levels. Was just looking thru some of my old measurements. This is a THD measurement of about 90dBC.
In room responses will vary from room to room, but lower tune modes should still be apparent in the same room, shouldn't it? In this 16-46+ in-room response, the lower port tuning did take a huge hit in the SPLs overall, although a bit more extension gain. 12hz is probably too extreme low...
When I used to have my PS-1000, I found that blocking 1 port appealed to my ears. It may not be necessarily better, it appealed to me. You could try blocking 2 ports too, but not all 3 ports for obvious reasons. But the PS-1000, being a bandpass subwoofer design could be naturally boomy...
You should get interesting results from the BFD. I used to have the same PS-1000 but I felt is was boomy on its own..... but try to sock the sub. Sometimes helps to curb the boom.
Teh DSP8024 and the DEQ2496 are autoEQ devices, but they are based on 1/3oct autoEQ for the graphical EQ. Not very useful in the LFE region because 1/3 oct is too coarse for any useful EQing for bass. PEQ is a better EQ for bass fequencies because certain bass peaks can be much much narrower...
