I am planning to build a new speaker to replace my
main system. They are wonderful but slightly large:
They are 6'2" and weight about 200 lbs.
I'm planning to build a 4th order sub in the basement.
This would be a 32 cubic feet enclosure with 4 x 12"
woofers. This covers the range 25-60Hz.
The port would go through the floor to the living room.
I would like to make the speakers a 3 way active
system with electronic or digital cross-over (4th order).
I will custom build the amps myself (Based on the LM3875).
I've looked at the tweeter and think I will go with one of the
LCY crossed over to a Fostex FE168 Sigma.
I need a woofer that will work well in a enclosure
of about 1 cubic feet (30 liters) and has a reasonable
sensitivity >89 dB/watt (As the amps will have not much more then
30-40W). The woofer will need to cover 60-250Hz.
Needs to have a very low distortion. I prefer an 8 ohm
driver as the amps really like 8 ohms better then 4.
I think a closed box would be preferred as there's no
phase shift to the port.
What would you use as woofer?
