Wiring help

[Jazon2000]

I currently am installing 2 dvc 8 ohm speakers in a big room and can’t seen to figure out the wiring setup. I’m trying to respect the impedance. Both on same volume control playing same music. The reason I chose 2 dvc is because the room is very large and wanted a L and R in each side. One side kitchen, other side dinning. Any help would be appreciated. Here’s a diagram.

No, don't connect the drivers as you indicated. You will damage your amplifiers!

You mean you want to run a mono signal to each speaker? I agree with Verdinut so far but hard to know what you're trying to do with what....what volume control?

Maybe this page might help you with understanding wiring DVC drivers, tho http://www.jlaudio.com/header/Support/Tutorials/Wiring+Dual+Voice+Coil+(DVC)+Subwoofer+Drivers/Tutorial:+Wiring+Dual+Voice+Coil+(DVC)+Subwoofer+Drivers/287544

It’s not wired, I just show the wires to the volume control, need to know how to wire the two speakers to the volume control now

That is not the intent of a DVC speaker. It is to either provide a speaker that has the option of allowing half the impedance of one voice coil with parallel connection, or twice the impedance of one coil with series connection. Also DVC woofers can make for novel design of Baffle step compensation. It is not intended to make a mono situation. Even though the coils may not be electrically connected if you put an amp with different signals on each coil, they will me magnetically connected which amounts to close to the same thing in many ways.

The way to do what you want is to sum the right and left channels before power amplification. This is done by engaging the mono button.

Your plan is not going to work. You need a different one.

So what is the impedance of each coil in your speakers, and what is the rated load impedance for your amps?

Is it a single stereo speaker, ie 2 tweeters?

 

[Jazon2000]

8 ohms

 

[Jazon2000]

Polk audio rc6

 

[Jazon2000]

Should I just return them and buy a left and right

You have always said that speakers with a crossover should never be wires in series, yet here you are, saying that a dual voice coil speaker can be wired in that way. That's wrong.

You don't seem to understand the intent of a dual voice coil speaker.

These ARE for allowing both channels to play from one spot. It's done everywhere and amplifiers don't fail because of it. Millions of these have been installed with L and R wiring and that's how they're supposed to be wired. It's not mono, it's stereo from a coaxial speaker without separation. These are made for places where two speakers can't be installed.

The input of the autoformers buffers the speaker impedance from harming the amplifier, although it's impossible to know if that will be effective without knowing what will be used as an amplifier in this system. Some volume controls even have extra taps to allow maintaining the impedance when up to four speakers are used on one control. These have been available for over 30 years and they work.

Show your volume control- if it has jumpers on it, move them to the correct position for what you're doing.

You don't need to convert to mono- forget about mono unless you ONLY have single voice coil speakers and two separate channels of amplification. Summing to mono before the amplifier is easy- summing after is more difficult.

Apparently it is. I though he was talking about a DVC full ranger. I wish people would post what they have.

I'm not sure many are using those with a volume control ahead of them.

But I did mention they are Polk rc6s

At least you understand my attempt

Would it be simpler if I just remove the volume control from the diagram since it’s confusing to some. And see if I can wire 2 dvc speakers either from one channel or 2. ( I do have a selector, if it’s needed or not) or to avoid conflicts I will just replace the 2 dvc with 1 left and 1 right. Since I know that works. Again my question is, can I add multiple dvc speakers to rooms on 1 channel playing with wiring setups for impedance. Again speakers are 8 ohms

 

[Jazon2000]

Receiver or amp is not purchased yet and may be on my needs

 

[everettT]

Yes but it could be easily construed that the "s" meant multiples not single stereo FWIW. I prefer keypads and a multi room source amp, along with mobile support. Mig

Would you want to use a volume control for each speaker? If so, you could use the selector ahead of the controls and not have any issues with impedance- connect it normally (stereo wiring) from the amp to selector, selector to control and control to speaker. The speakers are supposed to be connected to both channels.

My setup planned so far is amp/receiver to selector to volume control to 2x dvc
