Can someone with type R 12s (1222D or 1242D) check their spec sheet and tell me what the driver displacement is? I'm building a new box and my spec sheet is about 3 hours away, and alpine still hasn't updated their online manuals past the 2004 model. bunch of lazy b@stards. thanks.
Thanks rave'n, .071 cu.ft. I think is the added volume of the cone if you mount the sub inverted. I need the displacement which I think is somewhere around .3 cu.ft. but I can't remember for sure. Someone PLEASE check, I'm stalled till I can make the ports. Thanks a lot.
