Gran Gioia MK 3

The Gran Gioia MK 3, even closer to reality than before.

It was time to upgrade the Gran Gioia to the MK 3 version with our own developed 16" woofer.
The result reflects the additional qualities we expected. Our expectations were completely fulfilled and… surpassed.
We make 2 versions of the Gran Gioia MK 3, one version with titanium compression driver for the mid high range horn and one version with a more advanced beryllium based compression driver. The more advanced compression driver permits to have a lower cross over frequency and therefore the field of application of the woofer takes advantage of it as well. The further difference between the two versions is the sliding system of the top horn.
