Cubo Sub - Acoustic measurements with three different drivers was created by jjazdk
Hi All,
I have build one Cubo Sub, for test purposes with a number of different drivers.
Unfortunately I cannot talk much about the drivers, as they are prototypes not yet on the market
But all drivers are of course 18" PA bass drivers, with supposedly suitable parameters.
Attached are the measured responses.
Do my measurements look similar to other frequency response curves on the Cubo Sub, or..?
I find it very hard to find any documented measurements on the Cubo Sub, and I have used quite a lot of time googling for measurements to have an idea of what to expect.
The graph has 6 curves in groups of 3.
Lowest set of curves are measured with the microphone centered in the horn opening, and in plane with the opening.
Upper set of curves are measured at 3m distance with app. 150W RMS input.
All measurements where done outside, as seen on the photo (though on the photo the mic is at 1m distance from the Cubo Sub).

I have just gotten word from the company (SB Acoustics Pro division) behind the drivers, that I am allowed to share the T/S parameters for the drivers
