Remember the whole trying to figure out what my box was tuned to thread? My prefab Obcon ported box is tuned to 39 hz...thats from Obcon themself.
So, if I get a custom made ported box tuned to about (I got 2 12" Alpine Type-R's) 28-30 hz, would that make a huge difference in SQ, and SPL. I DO know that the lowest lows on some songs sound WAY less loud than a bit above. I deffinately dont get much of a flat response at all. Would paying $150-$200 for a box for the 2 be well worth it in the long run?
Yes, you'll notice a pretty big difference. I would honestly try to sell your Obcon box and spend a little extra to get the box done right. What's the sense in buying good subs and then dropping them in the wrong box?
What I really want to achieve is making the LOWEST lows as loud as the ones a bit higher, you know? Kinda hard to explain I guess. It sounds crappy when the song has a bass line with a super low note in it that hits hardly at all and ones higher shaking the car.
That would be because of the tuning of my box right? Also, what should I ask the builder to tune it to?

You could use a parametric EQ and cut the frequencies right around peak output to flatten things out. I tried boosting stuff right around 20 Hz with the one my Xtant has onboard. Works ok with my sealed stealthbox. Sound like @$$ with my ported 10w3's.
28hz is plenty low and a great SQ tune, most music goes down to around 30hz and that's about it. In the rare cases that it goes below 28hz, you can drop down close to 20hz safely, below that point you need to use a subsonic filter. You'll get a flatter response and a more balanced sound by upgrading your box, with better SQ, but your SPL won't really improve since you're moving your maximum amount of gain down to lower frequencies, you'll lose a little SPL and gain a lot of bandwidth and depth. Definately worth it though, IMO. As far as the box, detroit bass builds excellent enclosures.
So getting this box would make my subs sound better than most people you hear going down the street if they had the same subs? What do they usually go with, because I know its probably not a prefab ported box.
Lol, im so cautious, but I guess its good to be...I just want to sound good and not have stress over car audio lol.
