I have a pair of Nakamichi SP80 bass drivers (for car) that I'm trying to design a vented enclosure for and I would really appreciate any advise or help you can give.
The specs I have are;
8" driver
Fs 40
Qts .255
Qes .268
Qms 5.29
Vas 30.6 ltr
Xmax 7mm
4ohm
92db/w/m
So far the best I can come up (win isd) with is 22ltr, 42hz tuning and a port of 6x17cm
Would love to see what LEAP suggest as I believe you can add room gain or in this case Cabin gain being a small sedan.
size and power required are of no importance as I will use two in an isobarik setup with a 2x80wrms amp.
Not after Boom boom, after the best deep rumble I can get from them.
Many thanks....
Edit, found dimensions of car if it helps.
Passenger volume 2,670.3L
Boot volume 322.8L
TAAAA

Ta, 15 ltr sealed, now that s a surprise, everything i've tried it in says ported.
Freind has one in a 15 ltr ported tuned to about 47hz.
Whats the chance of bigger copy of that graph ? it's not quite readable sorry.
Yup diameter is exactly 180 (cone not surround)
Thanks for your help.
