Sundown 1000D weak bass??

[sundownz Pro Seller]

subs wired right. Its a D2 wired to 4 ohm....
Yes, I know I can wire it to one ohm, and I will try that. I just expected to hear MORE bass from the 1000D at 4ohm since it puts out double the rated power of the amp I was using before.

Likely it has more to do w/ the impedance rise. For instance, I was testing a sub the other day - 8 ohms nominal. Playing music it was rising up to 20 ohms and higher.

Say your 4 ohm sub is performing similarly, meaning ~ 10 ohms or so - the ED amp is "better at" putting out higher voltage as it was made for 4 ohms, which is what you need for this load, whereas the 1000D amp is more of a current amp as it was made for 1 ohm.

I'd say just wire it down to 1 ohm and use the amp how it was made for //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Adjust the gain down accordingly.

The 1000D has a phase control, I have tried it both ways and it really does not affect the output much either way.

Agreed

the 1kd is a beast...ii love it..its alot stronger than most folks think

but for wat u want i think the sax100.2 would have worked out well for u

very true, I think that knob was originally put on there for isobaric installations, at least thats what some older competitors told me.

Happy with mine, and that is all that really matters.//content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

Phase is not commonly used - it can be used to "time align" the woofer, though.

IT>EE imo lol

Prolly cuz I am IT.

EE to me is alot of commen sense and equations.

I can do alot of electronics with out really ever going to school for it. On the other hand you come and correct network 100's of computers together without any flaws and then we can talk.

I agree IT>EE. EE is its own little world that everything works flawlessly together and is easy to predict outcomes...

Computers almost never do what you want them to... (except for when you dont want them to do it)

However I disagree with your second comment... networking 100 computers with the proper equipment (and common sense) is stupid easy (at least that's just me...)

@OP: why would you even bother wiring it 4ohm?

Lol, you think it is easy to predict outcomes when designing a 1 billion transistor chip? Designing ICs and circuit boards is pretty tough stuff, plus researching new materials and things like that, there is A LOT more to EE than a lot of people think about. Btw, those computers that you work on being an IT were all designed by EEs //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Easy to predict the theoretical outcomes. However manufacturing processes are not always so forgiving //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif There is nothing overly hard about design. Sky is the limit. (and before you come back with a smart *** comment read the next line)

please refrain from replying to me as if I do not know what I am talking about. Also I am not an IT.

Most things are more complicated than they seem on the surface. Don't insult someone else's job just because you think you know what someone's friend told a person you know who in turn told you about working in a field associated with that job. That's just elitist.

People have a little sh!tfit about how their job is superior and more important and harder and whatnot. Honestly, we all need each other and one profession could not exist without the other (or not very well anyway). Can't we all just get a long and sing Bob Marley around a campfire? //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

On the subject of the subwoofer, I am with the people who say wire to 1 ohm and tune the gain accordingly //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Wow we are crapping on this guys thread. But you are wrong. They may be built by EE but not designed by.

What is it going to be out of phase with? Itself? The frontstage?
Neither of which will effect loudness. You only get horrible output from 2 subs being out of phase.

I would figure this would be the case, but I thinking my setup is an exception. When figuring which phase setting is best to match my subs to the frontstage, it was puzzled as to why one setting made the subs silent (subs still in phase with each other). //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

I'm thinking it might be a time alignment issue.

Phase is not commonly used - it can be used to "time align" the woofer, though.

IMO, the phase should always be used for subs, just like every other speaker in a system/setup. From the example above, I believe there is a correct phase setting depending on the setup/install

No, they are built on assembly lines. The chips and everything in them are designed by EEs. Your processor, designed by an EE, your video card, designed by an EE, your RAM, designed by an EE. The chips and stuff ARE designed by EEs, it's called VLSI design and if EEs didn't use it Intel wouldn't be hiring EEs to do it and colleges wouldn't offer it as an EE class, which they do.

YOu can study EE all you want. When you're done, you're still easily replaced by an Indian.

My last "easy" IT course was processor design.
