I know this is a dumb question but how do you know if your sub is a dual voice coil or single voice coil? Is it identified by the number of "wires" going into the back of the woofer cone? Yes yes I'm a noob when it comes to subs.. just trying to get into it..

Yes it is. Dual voice coils subs have 2 sets of tinsel leads attached to 2 sets of terminals. It usually is listed as one on the label too.

Mine doesn't say dvc or svc on the back. The speaker however has 2 tinsel leads for (+) and 2 leads for (-) but only one gold/copper "wire" going from the positive and same for negative.. so basically 4 leads and 2 "wires" altogether.. that's a dvc sub right?

While DVC subs have been around for quite a while now, I still love the statements and questions I STILL get from customers about how DVC subs are so much LOUDER than SVC subs.

Is it just me, or is anyone else still getting these?

What brand of sub is it? Does it have a model number listed on the back? Most manufacturers have some sort of coding of the SVC/DVC and even ohm loads built into the model numbers.

You have a sinle voice coil, the additional terminals are for ease of wiring purposes... It allows an additional terminal for parallel or series wiring with another woofer.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I don't know what brand it is.. it doesn't say. The symbol on the woofer is a big red "R" with a white lightning going through it. On the back.. all I see is a code "asmc-1r". I've tried googling it but nothing shows up. ust want to know if it's a dvc or svc so I can wire it accordingly for the use with my amp.

Would anyone happen to have a pic of what a dvc and svc coiled woofer looks like.. I've tried searching but no close up detailed pics can be found. Thanks in advance.

While this seems like a very stupid question, I appreciate you asking. I had a customer come in yesterday who had 2-2ohm subs with the same type terminals, which he had wired together. He said he had 2 2ohm DVC subs with the voice coils wired in parallel, and the subs in series. His amp was 2 ohms stable, so he wired them as such, but when he metered them, they were showing a 4 ohm load and he couldn't figure out why.

When you do the math, his thinking was right, but his subs were only SVC.

Hey thanks for the input. yeah after much of asking around from co-workers and such.. I do have an SVC sub.. sucks cuz I wanted to use the higher wattage feature on my amp.. oh well.. time for a new sub. Thanks everyone for the help.
