Never heard a true dual but I imagine it has a better tone than the corsa

I don't know about the sound difference as I have never listened to or measured the Corsa's. I'd like to, to be able to compare them to what I have.
This thread is as close as there is to what I have. It has a sound video in it.

It was done before the installation of the Helmholz resonator. I don't think a sound clip will capture any level of drone. Otherwise I would have done an interior one similar to the previous one.
The previous one didn't really capture the interior sound level. The db meter is what shows the actual difference. The meter would measure drone. Would need a frequency gauge for that.
