Subwoofer SQ?

Gold Member Username: Naledge503Http://com4.runboard.c... Post Number: 2352 Registered: Jun-06 | What is good SQ when we are talking about Subwoofers? Is it how responsive they are? If you are looking for SQ wouldnt the front stage make more of an importance? What would it sound like if you disconnected all front stage and just played the substage? How would you determine good SQ? Wouldnt the enclosure make much more of a difference than the actual driver? I've been thinking these things and then I found this. And it makes dang good sense to me. http://www.caraudioforum.com/vbb3/showthread.php?t=284551&page=1 Thoughts? |

Post Number: 12571 Registered: Jul-05 | well to a audiophile like alot of us on here & other forums who mess with car audio almost daily we can tell how "smooth" a sub reproduces low freqs & how low a certain sub can play (Fs plays a large factor) & be able to tell what a freq a sub is tuned to by just listening to it but the average person will just go to any local shop & pick out a sub which 'looks good' & while they r at the shop just for ease of convinience pick up a prefab box & drop in it without even setting any amp filters or other settings & their happy with that ... it all depends on how "in" to car audio a person really is ....  |

Or if you somebody has been into car audio for a while or not. Of course a prefab is gonna sound pretty shitty cause generally they are tuned high and you miss alot of the low end extension. But what happens when you throw that same sub into a custom enclosure? It will have better response and play flatter right? Say you have Sub A, bought from your local car audio store and it has an Fs of 31. Then you buy Sub B from one of these online dealers and it also has an fs of 31. Now you build them the proper enclosures and tuned at 32 Hz. Are you gonna actually hear the difference in the SQ? Or are you just hearing the difference in the response of the subs? |

Email Post Number: 4221 Registered: Nov-05 | how smooth the transition is from hz to hz... the ability to play all types of music without distortion and the ability to have nice frequency range without distorting on a higher/lower note enclosure, design, amplifier, and charging can play a major roll in the SQ of a sub as well as how you have your EQ setup or other settings also a good SQ sub will not had motor noise.. mechanical noise.. just a smooth note whether it be 30hz or 45hz.. you should hear just that note.. nothing else from the sub.. |

Gold Member Username: Arande2Rattle your ... Missouri Post Number: 2726 Registered: Dec-06 | Trying to explain it... A good sub is a sub that converts the electrical waveform from the amplifier into sound without distortion or non-linearities in the audio waveform. That includes, but is not limited to, power compression, bad transient response, high group delay, bad phase, and other stuff. Basically, it plays back what was heard in the studio when it was mixed. To do this, the sub must be able to move within its excursion range without non-linearities caused by voice coil heat, BL nonlinearity, bad damping, and other similar things. I don't need to get into a big technical explanation, that's good enough. |
