I have heard from Enrico that there will be an addition to the 1.Studio tweeter.
You will have a Studio 6.1 Neo (for excellent midrange), a Studio 6.1 Pro (for better midbass), a Studio 4.1 Neo, and possibly a smaller format Studio tweeter.
When I know more, so will you!
btw, the amps are supposed to be out in April. They are very pricey though...hovering around $2500 each. First one will 2x235 w most likely with the naming convention of 2235
