ported enclosure for 12" pg rsdc x2

[lithium 358]

need some help to come up with net volume and frequency for this sub. my friend will be running 2 of them in a blowthru and space is not an issue.

the gray line is the rsdc (2 of them) with 1200rms, the red is 2 12" AA arsenals w/ 600 rms, and the orange is 2 12" l7s with 1200rms

you can get the specs from the image if you like

pg recommended, according to someone on pheonixphorum.com, specs for ported are 2.5 cubes per sub tuned at 23.28 hz. (spl secs are .8 cubes and tuned very high... like 50 hz iirc...)

as you can see i bumbed it up to 24.5hz. but i still think this looks very low. i also notice you run out of xmax @ 600rms per sub.

just checked the pdf on these.. they rec a 3 inch diameter port thats 11.8 inches long.... that 23.3 hz... ~7 sq in of port area... has to whistle like a bird...

I'd definitely throw in more port area and a higher tuning frequency. However I have never used the subs so I don't know what would work best. If he is planning a blowthrough I'd imagine he wants it fairly loud? Definitely tune ~10 hz higher then.

when modeling with winisd it starts to get real peaky, ill post up a pic with afew options im considering. he's looking for 65-70% output and 30-35% sound quality, basically my idea was get some subs that will sound decently good and run alot of power to get them loud..

edit: ya the recommended port area is not gona fly... im probably going to go over board on port area since space doesn't matter.. and big ports look bad ass

bump with a question. should i pay attention to magnitude transfer function? comparing different boxes, i notice that the transfer function is less peaking with the rsdc's sq specs vs a box tuned higher.
