To help the sound of the
Grands even further the original feet were removed and replaced with
tiptoes, which improved the bass, focus and soundstage.
He had previously owned Divas. This pair originally belonged to Dan
D'Agostino of Krell. This pair are doubly unique as the have a servo
control added to the subwoofers (check right hand picture close up) which
was made by Dan D'Agostino.
The owner has removed the built-in amplifiers to the sub-woofer and
tweeter. The system is now driven by four Krell FPB600c amplifiers. He has
also removed the DAX's from the rear cabinet to put then in an separate
isolated chassis.
Information from the owner:
One picture shows the subwoofer servo hand made by Mr. Dan D'Agostino. As
I told you before, I think the Apogee's loudspeakers (all models) like
solid walls with irregular surfaces. No absorption, just diffusion. This considerably
improves the focus, dynamic, soundstage and tonal balance. I
also like to add some weight over the bases of the Apogee. With my Grands
I added 150kg of lead per channel in the rear of subwoofer's cabinet, that
very much improved the bass. I think that the Grand series (Mini Grand,
Studio Grand and Grand) have a heavy ribbon panel that is attached at the
front of the subwoofer cabinet (that 's not very heavy), so the ribbon
panel weighs down the front and affects the bass (some notes sound louder
than others). That's why is necessary to add weight on the rear of the
subwoofer cabinet. I think that this would also work with the Diva,
Duetta, etc. It's easy to try: just ask two of your friends to push (one man for channel)
the speakers supports against the floor and you will hear the difference
to the sound. |
