I cannot say for sure. However, 3 ohm simply means your speakers have less resistance and can therefore be powered more easily. I have never seen 3 ohm. It was always 8 ohm house and 4 ohm car. With 3 ohm speakers the receiver should easily push them, you will simply need to be extra careful not to blow them. This receiver will push a lot of power for those low resistance speakers and Okyo does not want to be held responsible for speakers less than 6 ohms being blown. Power them at your own risk.
Sorry, there was a problem. Please try again later.The previous answer is misleading IMO. Because your speakers have 3 ohm impedance and the unit is designed with a 6 ohm output, there is an impedance mismatch which usually means that some of the power will not be put through to the speaker. The speakers will work but not as efficiently as speakers with correct impedance match to its amp. It is a speaker's power rating (in watts) not its impedance that determines how loud they will sound when matched with an equivalent amplifier.
Sorry, there was a problem. Please try again later.Ohm refers to the electrical resistance of a material. The lower the ohms, the lower the resistance, which allows more current to flow through it. Resistance in an electrical circuit is what holds back the amount of current from flowing as easily. Every electrically functioning component has some level of resistance, including the wires you use to connect things to each other. If there is no resistance in a circuit, there would be nothing at all holding back all the current flowing within it. Heat is created when current flows too rapidly and can cause things to melt. This is considered to be a "short circuit" and signifies a component failure. When it comes to audio equipment and proper speaker to amp matching, the biggest things you need to consider are Power aka: Watts, and Resistance aka: Ohms. An amplifier, like this Onkyo, may be rated at a minimum speaker resistance (ohm) rating for thermal protection and equipment stability. The chips and other electrical components used within it may have a certain thermal rating before they start melting or malfunctioning. When you connect a speaker that has less resistance (lower ohm) rating than what is specified, it allows a larger amount of current to flow which produces heat within the circuit components. Ohms in audio speakers do not signify the quality of the speaker. They are neither good or bad. You just have to properly match your speakers to the amplifiers you are connecting them to. You may notice that at lower volumes, speakers with lower ohm ratings may sound a bit louder than speakers with higher ohm ratings. This is because the lower ohm rated speaker is not resisting as much power to flow through it allowing it to utilize the small amount of voltage a bit more efficiently. Watts is the amount of actual work the speaker can handle and what an amplifier can produce and is inline with current. You will notice that watt (power) ratings on amplifiers will change depending on the ohm loads. Again, this is because lower ohms allow more current to flow through the system, which in turn produces more watts, as well as heat. In this situation, I would recommend sticking with speakers that are rated to this receiver's 6 ohm minimum requirements. This will ensure you do not damage your receiver, and your speakers by sending too much current through them. You may be able to get away with 5 ohm speakers as long as you don't raise the volumes too much, but I would advise against it. I hope this may have helped someone.
Sorry, there was a problem. Please try again later.I would stick with 6 oh speakers, 3 ohms may run amp hot. That's why amp says 6 ohm min.
