Wayne,
Sounds like the 704 can use a cabinet similiar to the 416.
704-8A specs are as follows:
fs 30.9hz
Qts .261
Qms 8.49
Qes .270
Vas 16.35 ft
Eff 4.87%/98.5db/watt
I tried Pi-align and it gave me a 4 cu ft box, but I am still trying to figure out how to use it. Why does it ask for bottom cutoff, I would think the program would figure it out. I just used 40hz since I did not know what it was asking!
What do you come up with? Bill is building 10 cu ft box for me and that is exterior, I expect after bracing and driver accounted for that I will have approx 8.5 cu ft.
And yes, I used the port size from the 416 info since I figured it would be close!
Any comments here????
Regards, Ron
