Help needed with rockford fosgate box for 2 T2's.

[romans535 10+ year member]

does anybody have an idea on the right measurements for a double ported box for 2 RF T2's, I'm running them with 2 RF T1000.1bd amps. I need to make sure I have the right box and the right air space.

thanks

* 3.5 cuft for the 12s ( each )

* 5 cuft for 15s ( each )

? after displacement, seems a little bigger than needed

Bigger is better...

... LOL!

Probably could go lower.. I just like to go over needed/recommended

I like my subs to bottom out too. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Hmmm... I'd say 4cuft @ ( whatever hertz is goin' to suite you - genre of music? What are you aiming for, " SQL " or " SPL " or " Just to sound good - like Probox rocks enclosures "

....

Well, by decreasing the power you give it..

the box you see there is the one I had custom made

In the RF box wizard I put in the measurements and it says something like 6.7 cu ft

should i divide that by 2 for each sub http://www.rockfordfosgate.com/rftech/box_wizard/box_wedge2_out_on.gif

That'll be ~3.35 before sub & port displacement...

... So, sure.

the T2's have a 2.25 cu ft recommendations, so do I have too much airspace

 

[NissanKicker 10+ year member]

Nope...

The sub is gonna take .12 - .16cuft

.. And the port is probably gonna take maybe .6 - 1.2cuft
