Best SQ Sub setup

I noticed that most people doing sq competition will use 2 12's. Does a 10" woofer give less accurate frequncy slopes(10's seem to drop off steeply at the low end) or are the 12's used purely for the cone area to receive the maximum points which include hittin over 130db somthing like that. I want to get 1 10" but dont want it to be lacking in the low end and not keep up with those the high bass notes. I have had 2 different 10's and one of them got low but both would kill the high bass making the low bass seem very weak. Im not going for huge bass hear just somthing that is going to give a very balanced low and high bass. I have been looking at the Soundsplinter rl-i 10". But do yall thinks 12's in general sound better. Also I know the ported box basically solves this problem but I am wanting sealed due to space and my personal preference. Also in a reg. cab truck how could I figure out what my cabin gain is going to do to the frequency slope. I have had all of my systems in small truck could that be why the highs are so much louder?

10"s / 12"s, it depends on the insall. in you case you have limited room. you can get away with 2 10"s in a proper box. and it would sound great. but if you build a box for 12"s but dont have the right amount of space for a proper box, then you are not going to get the best outta the 12"s you know?

Yes I totally understand. I was also thinking 2 10's or maybe even 8's but I was gunna do one first just in case. I know bigger boxes increase low end to a point.....so your saying 10's done right can sound great like even low-high bass. I can beleive this but have not personally heard it most likely due to various details with previous systems. Is their any SQ reasons for going with a 12" instead of a 10"?

Plays lower, gets louder with less excursion required. Frankly, if you have the room and money there is really no reason to not get a larger sub. Especially if you plan on competeting (you referred to the 135db req.) A fundamental 11hz tone on a pipe organ is NOT an 8inch sub's best friend.:naughty:In the early days of SQ comps it wasnt' unheard of to use several 18's for subbass duty for lots of headroom. It's just a balancing act between, space, money, effective cone area, and power. Frankly, I've usually went with single larger sub setups. A smaller area usually enhances reinforces the lower frequencies. If you know your not getting enough low end find a larger sub that likes smaller boxes so you can put in a slightly bigger box sealed or a ported box tuned low, since you prefer sealed, I'd do the former.
