Kodomo,
A brief post about concerns. Feel free to discard it.
LF modules – are you sure that you want to go with ported
solution? You can model your boxes and use any good drivers but sonically with
port you will end up with bass that would hardly please you on a long run. In
so many words – it is known that I am only for sealed or infinite baffle but that
is me. Also the location of your bass channels. They need to be outside, not
between your horns. You can very easy to test it yourself. I am sure that you
will say that your room does not support it – well, welcome to the club of very
many people…. Anyhow, do try finding a configuration when bass channels are outside
of your main speakers.
A large glass window behind the horns is a bitch. Deal with
it somehow. Also, on the photograph the horn is sitting very close to the back
wall. I know that it is contra- intuitive but this type of horn topology is super
sensitive to the back walls. Try to move the horns for a good 5-6 foot toward
to the center of the room and you will see how dramatically the sonic presentation
will change. BTW, if you move the horn
for 6 foot forward then you will clear the entrance door and will be able to
move your right channels all the way on the right… gaining more width and
enabling to use bass channel to be outside the horns.
More about the requirement of bass channel to be outside. If
you did not make your boxes for bass then think again. The selection of TAD 1601b is fine but they are 16” that
would require a front baffle to be at least 20”. If you go with smaller driver
then you will be able to make narrower your front baffle. I understand that
larger driver is better but this will be not sub 20Hz woofers but bass module
that do 100Hz and they need to be geometrically at right position. The Supravox drive in the upper bass horn: introduce
another crossover point at let say 60-80hz. There is no reason to have LF signal
to bombard the driver if the horn will not produce it. Your sound from the
upperbass will improve then.
Ok, need to run to deal with baby. Sorry did not say anything
positive, not because your setup does not desire but juts do not have time.
Rgs, Me
