This was a firehose of information. Watch multiple times to get more out of it. All of what's in it are things I've learned over the decades. Good stuff.

Got to appreciate the work that goes into making these videos. Thanks Justin!

I'm only a little half Wade through this video and I just want to say I love it thank you

Wow, super informative! I knew most of this already, but this is great information to pass down to new bassheads. I do wish you had touched on damping factor, as it's an important concept. It shows how well an amp can control the current, which directly affects the subwoofer's performance. A higher damping factor results in better control, giving you improved sound quality and punchier bass.

12:19 "When you pass a coil through a magnetic field you create voltage". 11:41 - That impedance spike @ 62hz is directly due to the voltage the speaker itself creates as it moves its coil back and forth in the magnetic field. Since the cone vibrates the most at the resonant frequency, it creates the most back emf (electromotive force - voltage) back towards the amplifier. That measures as increases resistance to current flow therefore increased impedance. When you put that driver in a box that impedance curve will change. Anywhere on that new curve you see an impedance minimum the cone hardly moves back and forth (although it is sucking lots of power and pushing hard) and it's the boxes/ports/chambers/horns resonance that does most of the work. Anywhere on that curve you see an impedance maximum, the cone is moving like crazy doing all the work and the boxes/ports/chambers/horns are not resonating much.

Another excellent video! You should do one comparing power levels of parallel vs. series wiring using the same drivers, amplifier, and enclosure. This will debunk the term "box rise."

[TimpBizkit]

The impedance is both from the coil inductance and how much the speaker is allowed to move. If the speaker is allowed to move a lot, the impedance goes up. If the speaker is restricted by box loading, the impedance goes down. The speaker is generating a reverse voltage which has the effect of lowering the current going in.

did you really say that it doesn't matter if you wire a single 2 ohm dual coil sub in series or parallel because they both will give you 1 ohm? wow that's gonna screw somebody up...

[joshgreen]

Excellent explanation. Ive never been able to communicate it quite so concisely.

[Bobby]

I always paralleled mine back in the day. Dropped them to 2 ohms. Of course you have to an amp that can handle 2 ohm stable. I burned one amp up because of that. Lesson learned. Lol

[RedCan_Rick]

Fantastic, informative video. Another home run sir.

Ohm’s Law is a fundamental principle in electrical engineering and physics, describing the relationship between voltage, current, and resistance in an electrical circuit. It states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.

Ohm’s Law can also be extended to include the concept of electrical power. Power in an electrical circuit is the rate at which electrical energy is converted to another form of energy, such as heat, light, or mechanical energy. The unit of power is the watt (W). Voltage is electrical potential to do work ohms are the resistance to the work and amps or current is what carries the voltage it does the actual work. Watts are the power. V=I•R, R=V÷I, I=V÷R.

im sorry my understanding in english is not very good but which part is the more power and more bass connection ? 5:04 ? or 5:48

[hamiltoncouple]

Speaker “impedance”, when measured with multimeter is only electrical resistance of the coil, not speaker while being driven. While under load, speaker impedance continuously changes. Nominal impedance is usually the lowest at a given frequency which is a very narrow. Most impedance is much higher. I’m using Hertz amps which are 2 ohm stable, yet I have them loaded to 1 ohm at zero negative impact, going now on 3rd year, running them just below 15 Vdc. at high volumes.

[kadebrown]

What size wire do you use to connect the speakers to the terminal

[carlosv]

If you had a high impedance multimeter such as fluke 87v you measurement would be closer to the target reading. An oscilloscope should be the most accurate for reading.

[laszlosokolai]

Wire a dvc sub in series as it doubles the BL (hits harder, more control). Wiring a dvc in parallel you make the sub sloppy by cutting the BL in half and you kill the damping factor.

[carlosv]

How does a speaker make AC electricity? I'm curious because AC current will 100 percent kill your battery very quickly. Your alternator generates AC current but rectifies it in the rectifier bridge . The reason alternator does that is because otherwise you would need a new battery every other day

[billahler]

Idd so it more bass or just louder. Would buying a large enough amp do the same???

[RinksRides]

8x 8in DVC 4ohm subs. wire each in series, then parallel pairs to the 1 ohm amp. easy BBeassy!!

[antoniop]

Thanks I was about to parallel my sub to 2ohm but my amp is @4ohm voice coil.
