Exile Audio XPE12 12" Subwoofer 600W RMS

[newonty]

I bought this sub for a VERY good price and i received it today, looking at the sub it has 2 power ports rather than just one. not like positive and negative but theres positive and negative plugs then on the other side theres another set of plugs. why is there 2 i would like to know and i would also like to know if this is a decent sub especially for 33 dollars cad.

Hello newtonty, without a picture, I really can't say, but from what you are describing, it's a dual voice coil subwoofer. Basically, you have one voice coil for right channel and one voice coil for the left channel of your amp. Of course if you only have a mono amp, and the left and right channels are summed before the power amp, then you can wire the two voice coils in series or parallel, then connect that combination to the output of the amp. However when you do this you have to remember not to exceed the minimum impedance that the amp can handle. If you wire the two voice coils in series, then you get double the impedance of a single voicecoil. If you wire them in parallel, you get 1/2 the impedance of a voicecoil. Most amps can handle an impedance that is double, but many will have issues with a impedance that is halved.
So, show us a picture, and some more spec's on the particular subwoofer, and we can help more.

Peace,

Dave

Exile Audio XPE12 12" Subwoofer 600W RMS on eBay.ca (item 160413334631 end time 20-Mar-10 18:08:56 EDT) heres a link to the auction i bought it from it has all the specs plus pics. it says its a single voice coil.

Here's the link to the manual for your XPE12

There are actually two models the XPE12(single voice coil) and the XPE12D(dual voice coil) - my guess is that they use all the same parts for both subs(other than the second VC and if you have just the XPE12(single voice coil) there is just no connection for the second set of binding posts.

 

[newonty]

so do you think i got a good deal on it? because i was thinking for 33 dollars i cant go wrong

 

[newonty]

okay looking at that user manual it says absolutely nothing about the 2 plugs.

 

[Cal Weldon]

Look at the plugs. There are wires going from them into the cone. If there is one set, it's a single coil. If both have wires it's dual coil and you follow what Dave said. They don't usually put connectors onto the basket if there are no wires.

 

[event horizon]

If the driver specifications are right (which i have never found yet with any advertised specs for car subs ) you have got a bargain

Just don't go stuffing 600W RMS into it though, take it from me that copper resistance & glue etc hasn't really changed that much over the years & maybe 200W RMS continuous might be more realistic. It's only got a 2.5" voicecoil after all...

 

[newonty]

thats the thing there are wires going from both to the cone but the ebay thing says its a single coil thats why i am confused

 

[Cal Weldon]

Don't be confused. Accept that it's a dual coil and move on my friend. Check the resistance of the coils with a multitester to confirm whether you parallel or series the coils. What amp are you planning to use?

 

[newonty]

well i have a 600 watt sony xplod amp and i was hoping that it would work because i have no more money to buy anything else as i am only 16 and im getting my license on friday.

 

[Cal Weldon]

Is this the one? It's good to two ohms but the specs on the woofer are a little confusing. Can you measure them?

[Cal Weldon]

I would first wire them in series to see if that's loud enough and go to parallel only if it's not. A higher impedance is usually better for the amp and running them in parallel is not a huge increase in volume. Still I would check the Re with a multitester and make sure that each coil is no lower than about 3.5 ohms before paralleling them.
