Alright guys, i read all the posts religiously every morning when i get home from work. I read about sq, spl, and sql . . . i know sq = sound quality, i don't really know what spl stands for, but i know it basically means loud bass with high dbs. but i have now clue what sql is . . . my first thought would be like sound quality with an alot of bass too? :help:

SPL = Sound Pressure Level
SQL = Doesn't actually stand for anything. Means retaining SQ at high levels, like you said.

SQ is sound quality
SPL is sound pressure level (volume)
SQL is just an amalgamation of SQ and SPL. high volume sound quality.
