I have order 4cu feet sealed enclosure for two 15 drivers. It
is relatively small box but I need to hit minus 6-8 dB at 50Hz. The collection
of the drivers I have would be following: Vitavox AK51 and 15/40, Altec 416B
and 515B. I like Vitavox tone (a lot) and I love now 416B runs across dynamic range
with good SS amplification. The 416B has dynamic advantage in ported
configuration and I have no idea how the sealed box compression might hurt it. Vitavox
has great tone but it is paper-suspended driver and loaded in air spring it might
just stop “ringing”. The 515 is wonderful and has extra 3-4 dB sensitivity but
with extra magnetic force it a bit wrong sounding driver. You do not want to
have a woofer with 1.7T in gap… The most important is how to get the midbass channel
to get me 0dB at 100Hz and minus 12dB one octave lower. Sure a sharp filter would
do but can I do something more intelligent? It would be nice to tune the enclosure
size and thigh the pneumatic spring until I have proper SPL drop, however, how
will it affect the compression? The ultimate
fan would be if I were able to combine the Injection channel with Midbass channel.
Pretend a time-aligned enclosure with 10” and 15 drivers siting in own spaces.
I might even would consider in this configuration to go for ported topology for
midbass.
