Single vs Dual Voice Coil Speakers

[@anodyne6760]

Great video! Thanks for the info. I get foggy on these details from time to time. One suggestion: when shooting your videos, try and find a microphone that you can have close to you to capture audio. When you go to edit the video, just overlay the recorded audio and mute your camera's audio source. If you don't have that capability you can try splitting the audio from the video using various softwares and use something like Audacity to do a noise reduction process, which looks for white noise and tries to squash it. Audacity is free to use and fairly simple if you're at all familiar with what audio editing tools look like. Then you can boost the audio a bit and slap it back onto the video editing tool you used and you'll have much better sounding videos on YT for us to watch! It was a little tough to hear you guys at times as the white noise was fairly prominent throughout.

Thank you, we have upgraded our mics since this video.

1:35 - not sure the philosophy about dual voice coils is sound; if you will excuse the pun. Contrary to what’s being said/inferred in this video . . . Dual voice coils don’t usually make the design of the transducer simpler; single voice coils do. That said, I suspect the guys are referring to installation/sales, when they say “simpler”. As, a dual voice coil woofer (and its variable resistance configurations) can sometimes adapt more easily to most pre-existing and/or planned cabinet/amplifier considerations/combinations. However, there are a few substantiate/woofers out there in the market that have dual voice coils and only have 2 (not 4) terminals on the basket. Put simply the terminal count is not necessarily an indication of how simple, complex, and/or elegant the transducer architecture is. The JL Audio driver shown in the video at 50 seconds (with only 1 voice coil) is a very basic woofer design. In fact, so is the other one. Have a look at 18 Sound’s Tetra Coil woofers to see what goes into a good woofer design. But then, the car audio market is not really the most informed market in the world. Most of the time the guys that buy these and listen to them loudly in their car, are basically driving around listening to the repeated impulse response of the woofer over and over, and over again. When done right; dual (or quad) voice coils are useful because they usually enhance power handling; as - for applications where voice coil material/length is the same with a single/dual voice coil assembly - they spread the thermal load and allow it to be transferred away via conduction/convection quicker/easier. Dual voice coils can also be used to improve/enhance the electromagnetic circuit and overall electromotive design in various ways; including controlling stray inductance. Testing for and/or relying upon the nominal resistance figures as (shown in the video at various stages; including at 3:46) a means to select series/parallel configuration with the dual voice coil woofer and/or amplifiers, is - in my opinion - *not a very good approach. Still, I guess it’s better than not knowing anything at all and/or the nominal resistance; particularly for scenarios where an accurate impedance plot is not available. There are many reasons for my *aforementioned opinion (about why testing for and/or relying upon the nominal resistance figures is not always a good approach) but one of them is because it is the impedance of the transducer (combined with any crossover reactance) that really matters most and dictates what load the amplifier will be driving. And, the only way to know that is for the manufacturer to provide an accurate impedance sweep chart across all frequencies the woofer operates over and/or for someone to put the woofer in a sealed/ported cabinet that best emulates the end use situation.

Can I wire a single voice coil sub to a dual voice coil

[@300kapslar]

Why not connect 2 amp channels to DVC, one channels POS and NEG to one terminal POS and NEG and then the other amp channels POS and NEG to the other terminal without bridging?

[@stereoking7778]

You can do that, but most boxes only have terminal per sub.

[@300kapslar]

@@stereoking7778 My OEM sub has DVC and there is coming 2 pairs of cables to each terminal from OEM amp. Thinking of replace it but no one is mention that option so it makes me wonder if there is something else they have done with the OEM sub to make that work or the amp. The OEM sub is at 2 ohm on both terminals, if I buy a 2 ohm DVC does the two channels in the amp share/split the watt load or do they have to work as hard if I had power a SVC with one channel? The DVC and the SVC has the same specs.

[@stereoking7778]

Most factory sub amps are mono so they use a dual voice sub to drop the ohm load down. The lower the load generally means more power. So if you wanted to do a single voice sub you would need a sub at a 1 ohm load. It Usually easy to find a dual 2ohm sub than a single 1 ohm.

[@kylem8702]

Good video, but it didn’t answer my question. Maybe you can help. I have a 2002 Pontiac grand am with the premium monsoon stereo. Apparently it takes dual voice coil 6x9 rear speakers but I can’t find any. Can I wire up these 4 wires to a single voice coil speaker some how? 1 set for highs and 1 set for lows. I hope you can help! Thank you

[@stereoking7778]

It's not really a dual voice coil in the normal sense. The best thing for you to do is find a pair of six by nines that have a set of wires that can be disconnected from the main speaker terminals. For our customers I usually recommend the hertz dcx690s. They will have what you need. Just connect the two wires that come from the Tweeter and attach them to the highs output from the hip and then connect the low frequency output to the standard terminals off the speaker.

[@kylem8702]

Stereo King okay, so what you’re saying is I should get a coax 6x9 with tweeter wires that run from the tweeter down through the cone to the + and - posting. Then take those wires and splice them with my 2 hi freq wires, then run my 2 low freq wires to the + and - posts like normal?

[@stereoking7778]

Yes sir. Just make sure you cut the wires that go to the tweeter loose from the standard terminals.

good day sir...Does the tweeter and mid range are excluded in the final impedance? or are they included in the calculation...Because i thought that the calculation is only meant for the woofer and sub? just an ignorant question sir pls. enlighten me...my example is 8ohm woofer, 8ohm midrange, 8ohm tweeter in parallel...

[@stereoking7778]

Generally speaking the mid and the Tweeter are through a passive crossover Network which masks the actual impedance of each component. Typical crossover Networks have resistors added for the Tweeter and sometimes the mid that altar what impedance the amplifier will actually see.

[@ACommenterOnYouTube]

Care to explain HOW it will damage the sub..??

[@stereoking7778]

Think about it like a V8 motor. If unplug half the spark plugs you will seriously damage the engine. The same goes with a dual voice coil woofer. The motor structure and cone are designed to use both coils. If you only use one to push it it simply can't create enough energy to move it properly and ends up damaging the coil.

[@ACommenterOnYouTube]

ACTUALLY..... the 5.7L hemi engines from 2007 are designed to run on 4 cylinders to save fuel.... Granted any other V8 ... yes it can do damage because even though you cut spark... there is still air and fuel going in and compressing but not igniting... So yes it can hurt unless you shut off fuel & spark from those cylinders... then it will work ok as long as you shut the right ones off.... The engine must still be balanced, you must cut 2 from one side and 2 from the other side...and it must be in a cross angle firing pattern... or else you get vibration... back to topic.. Interesting... i keep getting mixed reviews on this subject and its almost 60/40 right now. Some say there is no damage and others like you say there will be damage... One guy even claimed he has been using his dvc sub for 5+ yrs and only has powered one side and its still working just fine..

You will need to worry about the impedance. If your amp is 4 ohm stable then you will need a 4 ohm sub, if your amp 2 stable you will need a 2 ohm sub. Etc. This is based on if you only using one sub of course.

[@2569dan]

I have a stock duel voice coil subwoofer. I’d like to put a larger boxed subwoofer (single voice coil) in my cargo area. Since I’m not changing or adding an amp I’m assuming I shouldn’t run both. If I don’t run both can I simply disconnect the stock sub and and take one set of positive/negative wires and connect them to the boxed sub?

[@stereoking7778]

Unfortunately to make this work properly you will need to add a amp. The factory amplifier will probably not have enough prower to run the sub you are planning to add.

[@2569dan]

stereo king oregon I think I have 75 watts going into each side of the stock amp.

[@stereoking7778]

I believe it's best to overpower a sub then under power it. The reason why is you tend to send Distortion trying to get more from the subwoofer when you underpower it. If you overpower it you tend to scale it back a little bit and then the amp it doesn't clip.

[@slowbryan0615]

I highly recommend getting a box made specifically for that sub. Believe it or not the enclosure plays a larger role in how the system sound than the sub itself.

What happen if you connect a dual coil sub to a bridged amp. In the scenario of using a dual 8 ohms subs making the funal 4 ohm resistance to the output of the amp.

That should work great! If you are bridging a 2 channel or 2 channels of a 4 channel amp, they are generally 4 ohm mono stable.

[@stereoking7778]

If a sub is rated at 100w that means it can only handle 100w of continuous power whether it is a single or dual voice coil. Lets say you have a dual 4 ohm voice coil sub that you have wired in parallel. That means your sub woofer will receive what ever your amp will make for power at a 2 ohm load. But you wire the sub series your amp will only make roughly a quater of the power that it would make if you wired your sub in parallel.
