the PDS221 was crossed at 2,500Hz, I adjusted the Synergy
for a slightly lower crossover of 2,000Hz.
would have liked to cross lower at 1,500Hz but during the
SPL sweep, I detected the PDB512 resonanting at that particular
back at the earlier impedance plots, my suspicions were
confirmed. A peak was recorded at exactly 1,500Hz.
cross at 1,500Hz, a conjugate network will have to be installed
to tame the impedance peak. Even then, it is questionable
whether it will be of any good as the corner frequency is
still at the resonanting frequency.
before, the Oriole
woofer was used for convenience.
the outset, it was apparent that the lower cross point resulted
in a much more distinct midrange. Vocals and instruments
now have the presence that was lacking in the PDS221. This
is exactly what I was hoping for. For me, it's crucial that
the midrange cuts right through the mix.
PDB512 sounded more relaxed too. No listening fatigue was
encountered after an entire day of music.
lived with it for a few days, I highly recommend the PDB512
over the PDS221. It is perfectly usable with a 8.2uF in
series. In fact, it's quite impressive, especially taking
the price into consideration. Of course, it can be better
when crossed with a super tweeter but that's for another
