i need some help with the basics

ok so here i go i was wondering what the difference between SQ and SPL is i can make the assumption by using common sense, logic and some research i have sone that SQ means sound Quality and SPL means Sound Pressure Level but i am still somewhat confused at the actualy difference between the 2. and from what i can tell the decision between achieving either of the 2 is a key factor in the design of ones system so if i could get a little help on this topic i would be much obliged... thank you in advance

SPL = loud

SQ = not so loud, but better quality

sq = sound quality (when you want the best sound quality)

spl = sound pressure level (when you just want volume, dont care about quality)

sql = combination of sq and spl (when you want it to sound really good and get LOUD)

ok thank you guys very much so from the sounds of it i guess i would like SQL. Given that i would like to know what the best kind of enclosure would be to use i currently have 2 Infinity Kappa 124.7w in a folded horn box and was wondering if that is the best box for my desires or should i go with a different type of box. i also was wondering about how much in general a custom box would run and if anyone knows of anyone in the San Diego area that would be able to make one

thx
