BL is, to speak generally, motor force of the speaker. BL distortion accounts for the vast majority of the distortion caused by a speaker directly (not to be confused with signal distortion, such as clipping an amp or pre-amp). BL optimization means the BL (motor force) of a speaker remains constant no matter at what point the speaker is in in relation to excursion. let me back up and state that a non BL optimized speaker means as the cone moves further from its resting point, motor force, and thus cone control, decreases. BL optimized speakers mean that motor force is (basically) the same no matter if the cone is moving 1mm or 30mm. As motor force drops, and thus cone control drops, distortion occurs. The further a non BL optimized speaker's cone moves, the less control the motor has over it. BL optimized speakers will relate the same force on cone cone control no matter how far the cone excurts (not a real word but I dont care).
The reason I mentioned it not as an end-all positive for the XXX is, some people actually prefer the BL distortion of speakers, as they are use to hearing it all their lives (BL optimization is a new technology). Many times when someone hears a BL optimized speaker, technically they are hearing LESS distortion, but when you've never heard a speaker that does not exhibit this distortion, its often is described as the sound is 'lacking' something they think should be there. Long story short, some people prefer hearing BL distortion, because they think it sounds 'right', when reality is its not true to the original source material. It would be like someone who has only heard tube amplifiers all their life, and when they hear a solid state system that lacks the 'warmth' (even-order harmonic distortion), they think it sounds 'wrong', when we all know these days that tubes add an artificial warmth to the sound that was not meant to be there in order to remain true to the original sound.

I hope that makes sense, Ive been drinking tonight. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I also learned something. I have no shame in not knowing things that relate to car audio, as long as I have things to learn there will always be interest in the hobby for me. I've never actually dealt with any systems even remotely similar to an SQ setup, so certain phrases and tech will be chinese to me.

I'm a convert into the SQ scene, so I try to learn a little everyday.

Thanks

Just happy I could help some guys learn. God knows Ive been on the receiving end of info on these boards plenty the past several years.
