you can try e-mailing them or calling them but im willing to bet you wont get a stright ansewr outta them. I have been trying to figure out the exact size for mine for months now and still dont no. But its worth a shot. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

True, ill do that and if i get anywhere ill post my results

Ideal enclosure size for an Eclipse Aluminum 12" woofer;

1. For SQ put it into a .9 Cu Ft enclosure, sealed with a back angled at 20-25 degrees off of vertical. Make sure to use at least 3/4" MDF, 1" is preferable and put at the very least 500 constant watts to it.

2. For SPL use a slot ported 1.7 Cu Ft enclosure tuned to 35 Hz and power with up to 500 watts. I you want to use a cheap POS amp make the enclosure a bit bigger but DO NOT exceed 2.0 Cu Ft, doing that will sacrifice alot of SQ and will most likely cause the spider to rip.

Dont worry a whole bunch about blowing the speaker in a sealed enclosure, mine is in .8 Cu Ft of fully corner braced 1" MDF and its eating 1000 constant watts like it's nobody's business. With the ported enclosure you dont want to go much over 500 watts. Hope this helps.

I'd go with 1-1.25cf sealed. You don't need 500 watts+ to make it sound good, that's just a myth. It'll sound great off of any reasonable amount of power. If you want full potential out of it, I'd say 500-600 should certainly do the trick.

I have the same quesiton

I have the spec there if you don't have it.

I am considering building a ported box, currently I have a .9-1 Ft2 sealed box.

It is good, but i don't think I used it properly. I don't know why, i just have that feeling.

Maybe we can help each other, consider you are in SI, I am in Brooklyn. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Well it depends on your definition of sounding "good" then, if you like weak, muddy bass with no punch, and a lovely distortion sound at higher volumes, go ahead and run it off of a 200 watt pos amp, if you want nice clear bass notes, with good definition and well defined shifts then you need power. thats all there is to it, you cant underpower speakers with a crappy, low power amp and expect them to sound good just by turning up the gain. This is a common mistake made by wigger types who want to squeeze out more SPL than is reasonable given their equipment.

Now dont get me wrong and think that I am saying there is no place in the world for cheaply made, underpowered amps that fake everyone out by advertising ridiculous specifications under the guise of ("Peak" power, or "Musical" power), its just not what I am about...look around at competitions and see that all the top SQ setups are running quality components, not profile, legacy, or other "brand name" car audio equipment. What you see there is a reflection of what is the best of today's technological advances in car audio and if you dont want to pay for that then you need to settle for an inferior system. Rant over, dont underpower Eclipse speakers, they dont like it.

You don't have the faintest idea what you are talking about. The ONLY way it's going to sound worse is if you are clipping the amp, period. Speakers do NOT sound better with more power. This is an inescapable reality of physics. To claim otherwise demonstrates a severe misunderstanding of how loudspeakers actually function.

You are just perpetuating an ignorant, poorly reasoned myth.

So long as you don't try and make the amp do more than it can (i.e. clip it), a larger amp will NOT be better. If you clip ANY amp, it's obviously going to sound distorted, whether it's a 200 watt amp or a 2000 watt amp. Provided that your amp doesn't clip at the output levels you desire, having a bigger amp isn't particularly important.

Lastly, how did you then devolve the amount of power argument to one on amplifier quality/brand? I don't recall that being mentioned in this thread, and it certainly isn't at all relevant to the post at hand. It in no way, shape, or form supports your other blatantly false claim.

I run a TC7 10" (same motor and a similar coil but slightly varied suspension from an Eclipse Alum) in 0.7cf sealed with about 225w RMS available. I have NEVER clipped it, nor has my sub ever been terribly distorted or inaccurate. If you think having more power when you aren't clipping the amp is going to make a difference, you are sadly mistaken.

Remember, no driver has EVER died from too little power. It's just not possible.

If you think having more power when you aren't clipping the amp is going to make a difference, you are sadly mistaken.

Remember, no driver has EVER died from too little power. It's just not possible.

Actually it is a widely known fact that drivers that are runnning on to little power are more subject to strain BECAUSE amps that are underpowered are more prone to being clipped, since their is not a sufficient power output available to adequately move the cone of the speaker. You have no understanding of how a speaker works if you believe that any speaker can be powered off of any amount of power and sound good. You say that you are running your speaker off of 225 Watts RMS power, well it probably is not all that loud then is it? I base all my knowledge on a large study of physical dynamics (including a Bachelors in engineering with a minor in physics).

Now, so that you dont go flying off the handle again without thinking first about what I said let me explain it so that those here who arent quite as swift can see the point being made. I am saying that an amp without sufficient power will be pushed to hard in an attempt to drive that speaker. A larger amp is most certainly better, now listen to the actual scientific reason why:

A larger amp that is capable of producing more power will not be overstressed providing the amount of power that a given speaker requires, while an amp that at its peak puts out just enough power will constantly be driven to its peak performance.. This analogy can be easily translated into the field of automobile engines: A car weighing 3000 pounds and having an engine horsepower rating of 100 HP will need to be worked harder to provide the same amount of acceleration as a vehicle weighing 3000 pounds and having a horsepower rating of 200 HP. Thus increasing the stress laid onto the parts of the engine and increasing the likelihood that the engine will succumb to premature wear. Now for those of you that are saying "well, an engine is a MECHANICAL device whereas an amplifier is an ELECTRICAL device." Well, to you let me say that amplifiers are subjected to internal wear by a constant flow of current through the circuitry, anything you can do to decrease the amount of electricity that passes through a given electrical component will obviously increase the life of that component.

Therefore, my statement:

."..you cant underpower speakers with a crappy, low power amp and expect them to sound good just by turning up the gain..."

Is entirely correct, if you underpower a speaker with a lousy low power amplifier than you will be forced to turn the gain up in order to extract an acceptable amount of output from that amplifier. So in essence what I was saying is basicaly agreeing with your statement that the only way to damage a speaker is to cause the amplifier to "clip". I did it merely in a different way, by using a particular speaker as the basis of my reasoning. And I specifically stated that the usual problem I see with people underpowering their equipment is that they are trying to get too much from too little:

"...This is a common mistake made by wigger types who want to squeeze out more SPL than is reasonable given their equipment...

And lastly to you as well, the way that I devolved the amount of power output into a rant (which I agree it is a rant with very little purpose) was to make the connection that most amplifier manufacturing companies use false advertisement in the form of "peak" or "Musical" power ratings to essentially lie to the uneducated consumer.

So, I hope you learned your lesson Warbleed, what people say can be interpereted many different ways, before calling someone uneducated and saying they know nothing about what they are talking about try looking at it from a different point of view, and realize that you are not the only person in the world with an understanding of the way that speakers work.

Incidentally you were correct when you stated that to get FULL POTENTIAL out of the subwoofer 500-600 Watts will do the trick, I should have given you credit for that, my mistake.

ok.. basically u two both know what u r talking about

this is just a simple misunderstanding.

1. too little power wont harm the sub IF the person doesnt overpower it, or else turning down to volume would cause everyone's speakers to blow.

2. too little power will likely lead to people turning gains a little higher than they should, and is likely send clipping to subs.

now we must ask ourselves, who is smart?

im gonna be running about 800 watts, i think that should be just fine
