6x9 speaker wattrms question

Post by Marc »

Sorry for the stupid question but i've heard different things and i know little about car audio...

Would you get any difference in sound quality between a 60 watt rms 6X9 and a 80 watt rms 6x9 if your just running it directly from a 50Wx4 headunit....???

I heard the lower 60wrms 6x9 would be louder or sound better than the higher watt speaker. Or wud it sound exactly the same with both speakers???

can someone clarify??
thanks alot

In my opinion, the 80 watt will sound better at high volume than the 60 watt providing you have a good quality amp. Your running 100 watts rms per channel right?

running just from a pioneer headunit 50wattx4, thats what it says on the face. not sure of the actual spec.

NO amp

do you think any difference in sound could be noticed between a 60wrms and a 80 wrms 6x9 speaker??

Yes there will be a noticable difference in sound quality. Due to the fact that the 60W speakers will be nearing the peak power rating, they will not sound as clear as the 80W speakers....

Not much of a difference, but it is audibly noticable.

It depends entirely on the quality of the speakers and the parameters (such as cone quality, surround complance, voicecoil resistance and 101 other things).. You'd really have to listen to them, and preferably in the car, to make the choice. There is no way to judge the sound quality based purely on the thermal power rating though...

ok cool...

what about if were talking about the exact same make of speaker, just 2 different power outputs?

I think to the contrary of the others here.

50x4 Watt Headunits is stating the MAX output usually. The actual output is usually closer to 15W RMS per channel in most headunits normally (ie, its not very good, hence why people use amps).

As this is more than likely the case, you will probably not notice much of a difference between the 2 speakers.

I agree with freestyler! You won't hear shit! Get an amp! They're cheap, easy to install and sound great! :beer

freestyler is correct!!! it also depends on the volts of your head unit a 5 volt head unit at 4x 50 sounds way better than a 1 volt out put i have a set of spilts than are 80 watts does that make a set of 100 watts speakers sound better i don't think so my splits are worth over $2000

Also most power ratings are a crock of shit on speakers and amps i have 2 amps at 2x 25 watts which were $1,200 each also 2 amps at 2x 50 watts that were $1,800 each does this mean that a amp that is 400 watts better NO WAY i never look at power ratings when ever buying budget set ups. Look for quality i spent under $700 in my new Jb For a 6 speaker set up using all ecipse equipment. which sound ok for the money compared to what i am used to.

Some of the more recent (and decent brand) headunits are quoting RMS power, but the easiest way to tell is to look at the fuse.. 200 W RMS (4*50W) would take a 25 A fuse at least.. less than that and you know you're being lied to. Amps on the other hand more often than not quote peak power. I don't get that at all. 1200W peak ~ 300W RMS, I don't think so..

The efficiency of the speaker (dbSPL/watt) will give you an idea how loud one speaker will be compared to another. Remember a speaker 3 dbSPL more efficient will make the same sound level with half the power, all other things equal, so a small nominal efficiency change can make a big difference to loudness.

Efficiency says nothing of the fidelity/quality/niceness/listenability of the sound though, that is affected by the frequency response of the speaker (how flat the curve is relating output sound level to frequency), the system driving it, the placementof the speakers and the general audio properties of the car, choice of music, mood and a whole bunch of other things also.

Sensitivity really has no meaning in the real world either. What a speaker can do with 1W has little to do with its output at 1000W under dynamic loads.

You can pretty much leave all specs where they belong, in catalogues, and use your ears.
