Just bought 2 12" Memphis subwoofers,and I have music coming from the woofers also...?

Question

is this okay,with my subs in the past all I have gotten from them is the bass.I bought these used and not sure if they have voice coils.and want to make sure that there isnt somthing I need to do to turn the voice off.I want to keep the speakers safe,and am unfamiliar with voice coils.I hope my question was spacific enough if not ask me what you need to know to answer my question.

Is there a way to turn off the voice,or is that feature suppose to be on my amp,If I dont have this feature on my amp,is it safe for my woofers to play with the voice playing also?

I dont have the low pass filter available on my amp,is this safe for my subs to have voice running thats all I need to know now.

Answer 1

Ok, to answer you main question...
No it is not safe for your subwoofer. A subwoofer is designed to play low bass frequencies. Not high frequencies....
This can cause your subwoofer to heat up badly.

Note:
all speakers have voice coils.

Here are some possibilities on why its happening...
Your amp may not have a low pass crossover to block out the high frequencies.
If your amp does not have a built in crossover than you will either need to buy an "active lowpass crossover" or a new amp with one. usually the older amps dont have crossovers.

you also might have a setting at your head unit where you can adjust what frequencies get sent to your subs and which stay at the speakers. unless you have a lower end head unit that might not have this feature.

Your best bet is that your amp does not have the crossover, or it does but you did not adjust it.
Running your subs like this could damage your subs.
And it is not a feature for it to play higher frequencies.

good luck

It is correct that all speakers have voice coils. To test if a voice coil is bad use an Ohm meter and ohm out the coil.
As far as the low pass filter check some of your car audio stores in the area several manufactures Pyramid I know use to carry an active low pass filter with a selectable bass range and an adjustable 12db boost at 40 Hz. An electronic crossover will also allow you to do this.
The 12db boost will help you get that real strong hit on the low end and if you set the low pass at 100Hz you should be fine. Invest in your mids and highs also.
In my vehicle I am running 2 10"JL AUDIO W3's with a Memphis 500watt mono-block class D amplifier. Mids and Highs are all Memphis. And I have my low pass set as such. It hits harder than a lot of 12's I have heard, It all comes down to how well you set it up.
Good luck I hope this helped...
Oh an after though, look up the speakers you have on the net find out what there RMS range is and get an amp that can produce that same amount of power stably. Memphis has a good line of class D amps that can fill this roll. Get the class D there are normally mono amps that are designed just for the bass frequencies, class A and B amps produce to much heat and it is harder on them. Class A and B amps are better suited for mids and highs.

I think you're getting confused by the term "voice coil". A voice coil is just the name for the coil of wire that makes up a part of every speaker, including every subwoofer. It's not just a feature of speakers designed to play voices. Some subwoofers have more than one voice coil attached to the same cone, which allows more power handling and more options for wiring, which is why some are "dual voice coil" subwoofers.

If you only want your subwoofer to play bass, then what you need to do is filter the higher frequencies before they reach the sub, using something called a crossover. Almost every modern amplifier has some kind of crossover built in; if yours does not, it would be very unusual. Look for a small switch labeled with something like "LPF", "HPF", "FULL", or maybe just LP and HP. If the switch is there, it should be set on the "LPF" setting. There may be a dial that allows you to set the crossover frequency; if it's on the amp, try setting it around "80". If you tell us your amplifier model, we can help you find the crossover settings if they're equipped.

If your amp doesn't have a built-in crossover, you can use an external crossover like this one: http://www.crutchfield.com/S-ZadQrXxvSx8/cgi-bin/ProdView.asp?g=82600&I=069900061&search=crossover or this one: http://www.partsexpress.com/pe/showdetl.cfm?Partnumber=267-766 .

If you decide not to use a crossover and let your subwoofers continue to carry the high frequencies as well as the bass, it won't hurt them, but it will hurt your overall sound quality.

Answer 4

all subs/speakers have voice coils. set the low pass filter on ur amp. what kind of amp is it? it would be easier to know the amp and sub models. also, what kind of cd player? some cd players have low pass

Answer 5

Check the low and high pass filter settings on your stereo (if you have this feature). If not, your amp isn't suited for these speakers.

Answer 6

it wont hurt them a bit just turn up the bass a bit and adjust your crossover on your amp and cd player and you will eliminate the problem
