fair enough, I only took offense to the comments about how terrible ported boxes were for his application, when, although a sealed box is probably best, a ported box could easily be worked in aswell, plus I was on a roll after bitching at that other guy //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

i use ported boxes for my dailys because of the output...however you put them on a rta and your going to have to do ALOT of tweaking to get a ported box to give a flat response like a sealed box on pink noise.

and at the shop i help out at i hear all kinds of bs statements everyday and i agree with them getting thrown around....the 12db i'm talking about tuning is at SUPER low spl like around 105 - 120 db where you won't really notice it to the ears but the rta does.

either way you wanna go though with your setup you would be fine i'd think, maybe tune a lil higher to get some more kick at some higher frequencies of guitar rhiffs but you'd be happy with a properly tuned ported box //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

what kind of box would be good for 2 12" type r's new ones. for the same kind of music?

Ever notice how a car that scores great on the RTA sounds like trash with music? The absolute best sounding cars have to be tweaked between the RTA and the listening tests. Competitors that don't go to the trouble of doing the tuning don't win overall, period. Flat RTA does not equal SQ. Get that idea out of your head. Because of the frequency sensitivity of the human ear, for the lower frequencies to sound blended with the rest of the frequency spectrum, it must be played at a higher level.

Unless you royally screw the basic enclosure size or severely under power the sub, even a sealed box will leave a shelf in the freq response on the RTA because of the progressive nature of cabin gain. Depending on the sub, you can get just as good a dynamic response and accuracy out of a ported enclosure as you can from a sealed one. It will almost always take a bigger box and the tuning has to be correct for the sub and there will be a hump in the in-car response in the 30-40hz range compared to a sealed box but it will SOUND good. It may score like crap on the RTA, but since I don't listen to pink noise and the sensitivity of my ears isn't a flat line anyway, who cares? Metal and hard rock sound great with a ported sub. That extra output in the sub-bass range IMO is even more important to the sound of metal and rock than it is to rap.
