4 Ohms & 8 Ohms Simultaneously ??

Will 4 ohm speakers work with an 8 ohm amplifier? Yes, if you use two 4 ohm speakers or or one 4 ohm resistor and a 4 ohm speaker to equal the 8 ohm resistance per channel. An important thing to note about this, is that you will need to make sure you get a resistor that can handle the current. You can go higher in resistance but not low…er, it must be equal to or higher.. Something important is added:. The amplifier will have an output impedance of around 0. In hi-fi we have always impedance bridging. Zout MORE Will running 2 ohm with 4 ohm dual voice coil sub woofers in parallel cause problems to the speakers or sound quality?

Why no 4 ohm Celestion Speakers?

What is the effect of running a 4 ohm sub from a 8 ohm supply? If the 4 Ohm sub was a pure resistor it would draw exactly twice the current from a battery than an 8 Ohm resistor would draw. However speakers are not pure resistors and the 4 Ohms rating is a not a pure resistance, it is a “reactive” load, meaning it has a mixture of inductance and capacitance as …well as resistance.

Oct 10,  · Your amplifier will deliver a lot more power connected to 4 ohm speakers than 8 ohm, so you could potentially overload it. Honestly I think it depends on the amp, higher end ones can usually handle lower impedance speakers whereas lower end models can’t.

Maryland jerrs I keep seeing you say SS amps are are self regulating. I am not sure what you are trying to say. There is nothing inherently self regulating in any common output topology. The limits on power are supply voltage and supply impedance. If the power does not double when load is cut in half, the most likely cause is PS impedance.

Extra current that can flow in the now lower load causes voltage to drop.

4ohm vs 8 ohm speakers – implications?

How do they work together? A 4 ohm speaker is a speaker with a nominal input impedance of 4 ohms. But what’s an 8 ohm amp? That cannot be an amplifier with a nominal output impedance of 8 ohms, because all audio amplifiers have an output impedance of less than 0.

Jan 01,  · You can wire both speakers in parallel for 4. You’d really need two 16 ohm speakers wired in parallel for 8 ohms, or two 4 ohm speakers wired in series for 8 ohms. There’s no problem mixing different wattage rating speakers, but you have to remember that you can’t use more than double the power of the lowest rated one.

Originally Posted by big ol shea I notice a lot of power amps I’m looking at for PA usage lately stuff like the Crown XLS or a cheap Behringer have four outputs presumably for two speakers and a sub. We have six stereo speakers and two subs we’re trying to hook up. What’s the best way to do this? My speakers are all 8 ohms each and I assume it’s the same for my friend who is providing the other speakers?

You’ll need to do some math before you hook it all up. Basically, you’ll need to find out what the output impedance of the power amp is and hook up all the speaker so that they match that. A lot of these amps can run at a couple of different impedance ratings, so you’ll want to make sure you get it within those specs. Mess that up, and you’ll probably burn up the amp. To hook these up, you’ll have basically two choices.

Run the speakers in parallel or in series. You may even need a combination of those two. To calculate the impedance of speakers in series, you just add up the impedance of each speaker. Let’s say you have three 8 Ohm speakers in series.

Monsoon amp …[zboner stay out]

One thing I learned pretty early in life is that speakers are not meant to be wired together in a haphazard manner. In fact, whenever you plan to connect more than two speakers to a two-channel amplifier — or more than four speakers to a four-channel amp — there are a few things to consider, not the least of which is the amps ability to handle low-impedance loads.

Ignoring the basics is like playing Russian roulette with your amplifier: If youre lucky, itll drive the speakers without incident; if youre not, the amp will fry. The great thing about a multiple-speaker hookup is that once you master only two basic wiring procedures — “series” and “parallel” — the world is yours to conquer. When you know how many speakers youre going to use and the impedance driving capability of your amplifier, youll be able to select a wiring scheme that will deliver the best sonic and electrical results.

Speaker Wiring Configurations but it’s important to be aware of how the speakers are connected up, as well as some of the implications of wiring up multiple speakers together. There are two ways you can wire a 4×12 (or 4×10 for that matter), the main one is Series/Parallel: 4 X 8 Ohm Speaker = 8 Ohm Load; 4 X 16 Ohm Speaker = 16 Ohm.

It’s german, but I’ll post the link anyway: Amp 8 Ohm, Speaker 4 Ohm: Risky, because the speaker will draw too much current at high volume. Amp 4 Ohm, Speaker 8 Ohm: No problem, but speakers will not be as loud as expected. Amp 8 Ohm, Speaker 8 Ohm: Right now i have non-matched surround speakers at home – the fronts are 8 Ohm, center and rears are 4 Ohm. The Receiver is set to 4 Ohm, and as expected everything works but I had to increase the level of the fronts as they don’t sound as loud as the 4 Ohm center and surrounds.

There might still be some general issues when cranking the volume up to the absolute maximum as it’s always a bad thing if you push the amp to its limits using speakers that can potentially draw more than than – but the amp will start to distort the sound quite heavily before the point where its dangerous, so nobody will normally do that anyway. I am not an electronics expert, so please correct me if I got something wrong. I am very sure that I got that one right, though.

Loudspeakers and Speaker Stuff

Originally Posted by Scottnot Older tube amps were designed with a specific output impedance; for best distortion free audio it was best to use speakers that “matched” the output impedance of the amp. Solid state amps are different; their output impedance is typically 0 Ohms and they are able to drive just about any speaker that one may wish to hang on them.

Yes, lower impedance speakers will draw more current and so the amp will run hotter or may overheat if the impedance is too low. However, since lower impedance speakers will draw more current at any given volume setting, they tend to “play louder” than higher impedance speakers.

On a Twin Reverb, there’s a 4-ohm secondary on the output transformer to develop the full (or 80) watts across two 8-ohm speakers wired in parallel (for a 4-ohm load). A Super Reverb has a 2-ohm secondary winding to develop 40 watts across four 8-ohm speakers in parallel (a 2-ohm load).

In my case, I also have the added burden that two of my main contributors are or were speaker manufacturers, some of whose products you will see as References below. Other associates are distributors of speaker lines. Accordingly, I made the only decision I could: All the choices in this category are mine alone. What I say to those who question my objectivity is; please closely read the rest of the References first to see my consistency and sensitivities, before making judgements on the few choices you may be understandingly skeptical about.

Any final and true judgement concerning these or any specific components requires a personal listening session with them.

I have four 4 ohm speakers connected in parallel to my connect:amp

It shows on the picture by the two AC outputs 7 and 8. I cannot find a download for the manual so I cannot confirm that both of these AC outputs are milliamps but this is what it looks like from the data on their website. Will this damage the unit? The amp comes with FX loop but currently my new setup is running everything upfront. I only want to gate my drive pedals and vibe. The pedals in use are as below:

There are two ways to wire four speakers to a two channel amplifier: in series or in parallel. Which one to choose depends on both the speakers and the amplifier, specifically their impedance levels and limits.

In reality, a lot of these variables are mutually exclusive: If you want maximum power output, be prepared to pay more for the drivers and sacrifice some frequency response. Keep these things in mind as you read over the next sections. A Note on Speaker Selection Don’t skimp too much on the speakers: However you can have all of the above qualities without spending a fortune. A word to the wise: However, like most older things in the music industry, they have a “magic” premium attached to them, and hence you must pay more to get them.

Try and stay away from speakers with cloth accordion or treated paper surrounds for any designs other than open backed. The surround on these speakers can be a large source of air leaks in sealed enclosures, which results in lowered efficiency. Remember, each 3-dB increase in efficiency results in twice the apparent sound level at a given power input. Most speakers for instrument use are very high in the high 90’s, and some are over for the wattage they accept.
