tbeats Posted April 13, 2014 Report Posted April 13, 2014 Ok so I have two sa12's d4 on a saz1200d gain set with a dd1 on -5db . Can crossover an ssf set with cc1. Crossover at 100hz an ssf at 30 Hz box is tuned at 34hz... So after playing today in 80 degrees sunny day for maybe 20min an went full tilt maybe 4-5 minutes on a track the dust caps was pretty warm ... Not like burning hot can't hold my hand to them hot but noticeably warm- hot... No smell..so is that normal with the sa??? Quote

tbeats Posted April 13, 2014 Author Report Posted April 13, 2014 What was your voltage at 13.8 dipped down to 13.1 max volume Quote
youngbass98 Posted April 13, 2014 Report Posted April 13, 2014 That's not bad. my sa 8v2 dust cap gets warm after full tilt for several songs. I wouldn't be worried Quote 06 monte carlo 2 12 rockford p3s soundstream rubicon 2500 crescendo audio mezzo 6.5 ct sounds 125.4 execution audio and shca wiring 2 xs d3400 on stock alt
Krakin Posted April 13, 2014 Report Posted April 13, 2014 This is normal for any subwoofer that has an air vent on the back of the motor. The dust cap pulls in and pushes out the air around the coil. As the air passes that hot coil it heats up, it then hits the dust cap and transfers some of that heat to it. Don't worry about it.

I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.
tbeats Posted April 13, 2014 Author Report Posted April 13, 2014 On my other system two kicker L5 15's that have a kicker zx1000.1 on each sub have never gotten as warm as these sa's... But now keep in mind my sa's are firing upwards in a hatchback Sun hitting them also... Maybe I'm just paranoid.... Quote
Krakin Posted April 13, 2014 Report Posted April 13, 2014 The surface area on an L5 15's "dust cap" (or whatever it would be called in that design) compared to the surface area of the dust cap on a SA 12 is significantly smaller. Larger surface area allows for a faster transaction of heat. This may be why you didn't feel anything. It is also possible that underneath that eye-catching cone there is a real cap that absorbs the heat and nothing is felt on the cone.

tbeats Posted April 13, 2014 Author Report Posted April 13, 2014 Only thing strange to me even after setting everything with them dd1 sub amp at -5db track 3 the clip light on my amps remote gain control is solid red when jamming hard ... So who's right dd1 or the amps clip light? Quote
xxgokouxx Posted April 14, 2014 Report Posted April 14, 2014 I was wondering the same thing as you, except I have an SA-8. Now my questions are answered as far as that.... Onto clipping, I have the at1400.1d, and was also wondering if that was clip indicator comes on EARLY, because my voltage is stable at 13.8v, and I don't see anything lower than that. I also don't feel or hear distortion at all, nor do I hear clipping. Quote
Krakin Posted April 14, 2014 Report Posted April 14, 2014 Clipping won't necessarily make your voltage drop. You also won't hear the clipping when it first starts. You will have to have a fairly large clip in order for that to happen.
