I'm gonna bump this thread now that CAFO is on these forums, and he has extensive experience with the Rockford range:
T115D4 is currently in 2.24 net cubic foot sealed box. I'm generally happy with the output, but im looking for more. Just wanted your opinion on going ported. No-one could give an opinion from experience which im hoping you can. Rockford tune looks high... and the group delay sacrifices look considerable. Thanks mate appreciated
PS - please PM me the cost of a T212D2 and T1000 amp, as well as the cost of the 15 version... i MAY be buying in late Jan if it goes ahead. As usual i commit to nothing

The T212D2 is $699.00 about $700 saving over any other RF Dealer!!!
The T10001bd is $ 850.00 and the T20001bd is $1450.00
I would suggest the T20001bd so you have to opinion later of adding another T212D4 plus gives you a few wiring options.
Depend on what you are trying to do with the SQ or SPL with the Sub etc to where to tune it to.
Here is a bit of temptation on the T212D4... very nice looking sub... like the T115D4
Port Box from experience on these Power SUBS will give you more low HZ and hence more DEEP BASS, though if you are after just base I would suggest to go to a SVC not a DVC.
I prefer the DVC Power sub range and they can be tuned to DEEP PENERATING BASS... again depends what you are trying to accomplish.
As for the
T115D4 - We found the best for the Vented Enclosure is the following to get the most out of the T115D4
and will make a big differenct over the 2.25cuft
Recommended Vented Volume Internal: -- 2.75 cu/ft - 77 litres
Recommended Number of Ports: -- 2
Recommended Diameter of each Port: -- 4" - 100mm
Recommended each Length of Port: -- 16" - 400mm
The 2.24 cuft is the Min size for your sub and the max would be 3.24 cuft
Though stick to the top and you will not be disappointed.
PS the T212D4 is a much prettier SUB!! lol.
