Questions for Soliloquy fans
From the post by Jax2:
The 'i' versions of the speakers are
the newer versions of each of the models. They went from hard corners
on their cabinets to rounded corners. They also changed the drivers and
the 'i' version drivers seem to be aluminum or some metalic material.
The new drivers look very similar to those used in their sister line of
speakers AAD's E-series, but appearence may be where the similarity
ends.
