bass juggernaut Posted June 20, 2013 Report Share Posted June 20, 2013 so i was on the "cone area" thread and seen Ray say the first thing she looks for in a sub is "BL first then XMAX then QTS and QES then watts" and i would like some one to elaborate on that and why those matter and what they mean (the simple version) i really appreciate it since i will be purchasing new subs tomorrow either AB HD1822 or Obsidian 18 D2 or AQ HDC3 those are what i have narrowed it down to.

Azagtoth502 Posted June 20, 2013 Report Share Posted June 20, 2013 http://www.bcae1.com/ also motor size doesn't tell the whole story and low FS does not mean the speaker will play lower. pa-pa-platypus sorry not everybody has a companies nuts so far down their throat they catch every drop ball sweat when it falls Link to comment Share on other sites More sharing options...
BoomZoom808 Posted June 20, 2013 Report Share Posted June 20, 2013 As I understand it (I am sure an expert could provide more accurate/better description) - BL - How strong the motor force is of the speaker XMAX - Max distance the cone can travel QTS/QES - The mechanical and electrical amount of control/dampening in the speaker aka the brakes to stop the cone going one way and send it the other. 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...

BoomZoom808 Posted June 21, 2013 Report Share Posted June 21, 2013 Sorry no can do a vs thread it is against da rulez. 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...
SnowDrifter Posted June 21, 2013 Report Share Posted June 21, 2013 VS threads are not allowed Neither is rent-a-modding BL is the force-current ratio. If you know the BL and the Re you can find the motor force by using bl^2/Re. That's why dual 2 and dual 1 coils have different Bl values. But if you calculate the motor force they are the same Xmax is how much the coil can move, one way, before it leaves the gap. Generally your maximum usable excursion Qts is a function of Qms and Qes. A combination of mechanical and electrical dampening Qms is a mechanical dampening And Qes is an electrical dampening. ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
