Hey Mr_Bob,
the TS specs are:
Fs: 26hz
Qts: .39
Vas: 120l
Xmax: 14mm
Sens: 88db
Power handling RMS: 500
displacement: .21 cu ft
Anything else? those are the only specs rockford has....
I thought 26hz Fs is really low, i dunno?!
Help! Ta

reasonably low, i've seen 22Hz and a number of subs between 22 and 26.
sorry i forgot what you are after,
how much box space? SQ i assume?

do you have Qms or Qes?
quick inspection i'd go for a 80-100L box tuned to 28Hz or so.

ok i double checked a 100L box (per driver) tuned to 28Hz is hella flat down to ~38Hz, then an even roll off to a -3db @ ~28Hz. which looks almost like a perfect 24db/oct HP.
so if you're car's transfer function is 24db/octave and starts boosting at 38Hz, you'll have a super flat response
group delay is not so great under 40Hz, it peaks at 20ms at ~28Hz which isn't terrible
a 100L sealed box starts to roll off at 300Hz the -3db is at 60Hz, that can't be right.
anyway, if you can grab those other specs i'll double check again cause the sealed box just doesn't look right to me, and i would have thought these subs would be ok in sealed.
if the group delay bothers you, try tunign higher, around 30-32Hz, this should minimise it.

Hey Mr_bob
Yeah, i think winisd is screwy, i think the cars peak is around the 46hz mark.... i have up to 120L to play with So, anything under that is fine.... I'm only going a single driver i think...... either that or decide on a different sub.... But i'm thinking of getting one, thats never been powered, blah blah, HX2 rockford for around $350 mark.......
So, it seems good price wise!
Thanks!
Az.
P.S. I can't get any of the other specs, they don't seem to exist!
