Box for RF T115D4

[Joe Peeps]

Hello all,
Bought a Rockford T115D4 and will be building a box for it soon. i have been fumbling around in winisd and the Rockford rec ported have big group delay and gain peaks. im after real world experience with sizes and tuning. I'm thinking ~2.8-3cuft tuned to 30hz?? or sealed 2.25 as per Rockford rec. Sortof an SQL kinda vibe..

Qts: .501
Vas: 89L
Fs 28Hz

Cheers

i guess you mean an SPL vibe?
so you want max output over quality?

[jds303]

SQL, sound quality level, a combination of sq and spl.

[garfa]

haha ok.
well i dont really see the problem, build a temp box a bit larger than the reccom. box size and put bits of wood in it till you like the sound. the figure out the total volume of the pieces of wood and subtract that from the original box size.
yeah?

[Joe Peeps]

Yep, Jds is correct. I was going to build the box ported, and then if i didnt like it fill it bricks or something and plug the hole, then i realised what a hassle it will be to make a ported box then not use the ports. I was hoping someone else had the same sub and could impart some experience thus saving me the time and effort... (some may call it being lazy) No substitute for doing the work i guess. Thanks for the input tho.

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.

PS

If you still go the 2.24cuft which is out by .01cuft

should be 2.25cuft

you can vent it though you will need to extended the above ports by 4" to 20"

YES INSANE though ... TRUST ME!!!!

Joey, this may help as well

Dont forget to use the RF supplied gasket under the facia of the Woofer when you put it in the box..
