Myth Busting: Damping Factor - A Misunderstood Rating

 

---------- Post added at 09:46 PM ---------- Previous post was at 09:45 PM ----------

 

Now go away and only come back to talk about the woofers you are designing to be the best ever.

i've already explained this. butler say that because of there POOR *** feedback. no thanks.

its simple if you cannot pull the inductance out of the circuit its going to generate feed back and alter the signal. these articals are old as me. the new stuff on the market has WAY bigger inductors and motors than they ever tested.

the feed back in the new high output drivers are WAY higher/stronger than they measured. sure in 1995 when you have 150-300 watts with a voice coil 2"s dia by 20mm tall and a 4 ohm RE the dampening factor was plenty high.

meaning that the amps output impedance was low enough to absorb it.. in the last 10 years that has all changed.

look at the parts used today. there resistance is higher as output increases and cap-banks have a higher ESP. there are ways around it but most companies dont use any techniques to increase the damping factor.

thats why these cheap amps sound like ****.

you say SQ in speakers is snake oil. dampening factor doesnt matter. it shows how little you actually know about the industry..

My team member has a 3500 at .5 on 4 shok tritons and actually sounds pretty good. No weird sound signature.

as compared to what? if you dropped a zapco reference and a acoustic elegance driver with the lamba motors and some real music like off a drum line, or piano Id bet you hear a difference. but needless to say Id imagine it doesn't sound sloppy but as far as the actual signature. you have to compare it to something worth comparing to..

damping factor is just like anything else. to much feed back and too much damping can have ill affects. its one of those things that like los said is kind of irrelevant because most good amps have PLENTY there are cases where you need the higher damping because of the amount of feed back.. i bet if you listed to a well tuned sub and amp not in the truck cause that able to makes 10-15% distortion you would hear differences.

very very few people go out of there way to do this testing and wwhen they do the field testing so very narrow and doesn't account for alot of situations that are realistic.

the US amps are soild stuff. unlike that cheap Chinese **** AQ has..

I looked at there amps a few years back and they seemed like lower midrange Korean boards. Thats unforutnate if they outsource it to a cheap Chinese source

misprint. sorry. the US acoustic amps. they are good budget amps and they are from china as well. but its not that china doesnt make great amps. its just the people who source Chinese amps source the CHEAP ****.

I wasn't comparing to super high end amps. I never heard any amps that super over priced like that. But compared to your normal Korean boards I didn't know any difference in sounds. I have a fsd 2.6k just waiting on my soundrive 12 hopefully no issues.

like i said. they have good and bad from everywhere. china DOES make good stuff. but your going to pay. Toshiba is know for making highend electronic components and they are in japan.panasonic is know as well for making highend components again in japan. nearly al the components used ome from china or japan.. even in the Korean boards,

i dont know if jacob is still using the faichild transistors they are out of USA. but again they have lower line stuff and they make higher end stuff.. it just depends. companies like arc and zapco use proprietary circuity and chinese parts for the most part but they are excellent amps. it has alot to do with the circuitry and alot to do with the parts. just like some parts are superior some circuits are superior..

im not trying ot be a **** but super over priced means what? example Rockford Fosgate T600-2 Power Series 600W 2-Channel Amplifier 500 bucks wit a typical class A/b desing an no real feedback(still sounds great no doubt)

KS 300.2 - ARC Audio 2 Channel 700 Watt Amplifier Class H with feed back and greater efficiency. rivals the highend class AB amps 20 bucks cheaper.

people just buy re baged junk and think its good.

No it shows how gullible and inexperienced you are.

I'm talking these "sq" amps that are double the price.

it's a 2000, yeah there's actually a throttle cable on mine. it adjusts just like yours does but maybe its much much slower. also maybe because your load is distributed the computer is already increasing the throttle to maintain idle

Yeah, no throttle cable on mine. All electric. It sucks because if the computer throws codes, the engine RPM is governed to 1500 //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

You will never hear a shift in dampening factor. You can barely measure it. Sounds like his filters where set different or the FSD was running out of power faster. No dynamics.

Your ears might not hear it, but the meter does. There are a few tenths difference that can be made. To most people, that doesn't matter whatsoever. To people chasing tenths, it's a big deal

Countless times ive been full tilt approaching a stop and the engine has died. Thats not counting the numerous times ive had to lower the volume to save the motor just before stalling.
I dont ever think ive seen lower then 11.7 during this current pull lol.

I've been doing this longer than you!

what I'm telling you is what a lot of people who build amps will tell you..

some believe feedback is bad some think feed back is nessicary. it depends on the design. your **** off sites are from companies that offer NO feed back and have high *** output impedances. IE low dampning.

fact is that most high END tube amps have very low dampening factor(10) they fair horribly with feed back.. I don't like um and they are snake oil.. the real RIP OFF.

if you know anything aboubt basic electrical you know that back emf can pleauge the signal. its the reason we are using inductive based distortion analysts. high inductace and inductive loads that have greater back EMF. this plagues transient response.

not so much as in frequency response but the drivers abilitly to reproduce more than one tone in a defined period of time and return to its rest position.

Blah blah marketing bull ****. Go to Scrappin and bring your favorite CD. I'll let you sit in my car as long as you want. I promise you won't want to get out. Then tell me what's not snake oil.

and it you turn off all EQ and processing it will sound like ****. its simply a tricky way to altering the soundstage lower than the levels most people can perceive. that's not low distortion its simply masking the distortion.

Lol. You really are clueless. Sure I'll defet the EQ to show you what it sounds like with no magic dust. Then you will see how important that EQ dust is. And what really matters.
