Difference in amps to power subs
|
Silver Member Username: Iufan4lifeulPost Number: 524 Registered: May-05 | Ok, so honestly. When it all comes down to it what is the difference in these things. Like most people say, the distortion is never an issue on these amps. Now, I am not going to compare a Pyramid with an Orion but if say, for example you run a 1200rms Orion vs. the Kicker 1200.1 what would be the audible difference between the 2? I realize that the difference might be heard if you were powering speakers with it, but with subwoofers could you TRULY tell the difference? |

Gold Member Username: Taylor17Kopperl, Texas Post Number: 3116 Registered: Jan-05 | Yeah, good point. I'm not in to amps as much... I know just enough.:-) |

Gold Member Username: Basshead86Ocala, FL USA Post Number: 2217 Registered: Aug-05 | i wasn't arguing with you, just adding to the cause. i read somewhere that up to 10% THD is inaudible in a car environment(road and engine noise). but i could be wrong. |

Gold Member Username: Taylor17Kopperl, Texas Post Number: 3118 Registered: Jan-05 | Lol, I didn't think you were... but it wouldn't supprise me if thats true. I could see how you might be able to tell on tweeters or speakers... but on subs, I find it harder to believe an amp can make an sq difference. I'm prob showing some of my lack of knologe about amps by saying that. |

Gold Member Username: Taylor17Kopperl, Texas Post Number: 3120 Registered: Jan-05 | Well, you were right. THD has a little part in it, but not that much over all. |

Silver Member Username: TdisantoPost Number: 387 Registered: Sep-05 | damping factor plays a much bigger role than THD + noise. It directly effects sound quality bc it reflects how much control the amp has over the driver. |

Gold Member Username: Mikechec9Http://www.cardomain.c... Post Number: 1205 Registered: May-05 | actually, damping factor is very overrated. if the number is over 30, you won't tell a difference. thd, s/n, power supply, all very important. thread for thought i dug up as a muzzle on another thread. |

Silver Member Username: Iufan4lifeulPost Number: 525 Registered: May-05 | according to this site (http://www.soundsolutionsaudio.com/forum/lofiversion/index.php/t3103.html) dampening factors can get over the couple hundreds. My kicker 450.2 is rated at 250 or so according to them. That ain't bad. |

Gold Member Username: Mikechec9Http://www.cardomain.c... Post Number: 1209 Registered: May-05 | yeah. the average is 100-200. but that's the thing. so long as it's above 30, you are not likely to notice a difference. |

Gold Member Username: Basshead86Ocala, FL USA Post Number: 2235 Registered: Aug-05 | he's right, it states that on bcae1. but i would rather have a damping factor of 200 and a thd of 1% than a damp of 30 and a THD of .0000000000000000000000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000001%.  lol |
|
Gold Member Username: Taylor17Kopperl, Texas Post Number: 3138 Registered: Jan-05 | Lol... was all that needed?:-) So is a THD rating of 1% better or worse than THD of 0.05%... because I've always thought the lower the number... the less distortion. |
|
Gold Member Username: Basshead86Ocala, FL USA Post Number: 2240 Registered: Aug-05 | yes, the lower the number the less distortion, but did you read that link i posted? |
|
Gold Member Username: Basshead86Ocala, FL USA Post Number: 2241 Registered: Aug-05 | here, i'll show ya. "Many people believe that THD below 1% is not audible and I believe they're probably correct. The fact is, especially in an automobile, the amplifier is the least of your worries. Speakers used for mids and highs commonly produce between 1% an 5% THD and for subwoofers the numbers can easily reach 10%. This doesn't even take into account all of the resonances of all of the plastic and metal panels in the vehicle." understand? |
|
Gold Member Username: Basshead86Ocala, FL USA Post Number: 2242 Registered: Aug-05 | there are so many other noises in a car, that a THD of 1% or lower really isn't an issue. unless you listen to your music in the middle of a field, with the windows up and just the battery powering everything. lol |
|
Gold Member Username: Taylor17Kopperl, Texas Post Number: 3142 Registered: Jan-05 | Actually, I do. You may not be able to tell a difference from just 1%, but when looking for a good amp, you would want the one with the lowest THD, and the highest dampening factor right? |
