GRF PRO plans by Enrico




The driver is in this design, more or less, at 65 cm from the floor.
Putting a plinth under the enclosures would make them more than 150 cm
high, which, given the width of 80 cm, would make them too cumbersome. 
I even thought of modifying the first part of the horn so to accomodate
the driver at approximately 85 cm from the floor, but I don't know if
that would make any good: I believe that if GRF made such a design,
there's surely a reason. Probably I'd have built an unbalanced design.
