Can I Use An 8 Ohm Speaker With A 4 Ohm Amp?
For solid state amps (even with tube preamps): Running an 8-ohm cab from a 4- ohm-rated head is just fine. You'll typically get a little more than half the rated power of the amp, though. Running a 4-ohm cab from an 8-ohm-rated head would result in excessive current draw, and could damage the amplifier. 30 Aug A: There are many variables to consider when connecting 4 ohm speakers to your system. Please consider the following: Define your system. Are you using a Receiver or separate power amp to drive your speakers? Receivers: Most midfi Receivers may have problems adequately driving a 4 ohm load. Negative side of Speaker D. 4 Eight (8) Ohm speakers wired in Series Parallel = a Total. Load of 8 Ohms. SPEAKER IMPEDANCE MATCHING & HOOK-UP 8 OHM. 4 OHM. 4 OHM. Partial back view of some Mesa amp. 8 Ohm Cabinet. SAFE MISMATCH. WIRING SCHEMES Amplifier to Speaker Cabinets. 4 OHM.

I just found out that on one of my amps, the 4 ohm speaker connects banana plugs I had feeding 8 ohm speakers - been this way less than 2 weeks. I found how to do it, both 4 into 8 and 8 into 4, but I don't want to know how to do it - just what happens when its done. How I did it - I was running my tube amp into 4 ohm Maggie's, then over a week ago I pulled the banana plugs from the Maggie's MG-I and just plugged them into 8 ohm speakers, not thinking the other end of the wires were fed click the tube amp 4 ohm speaker connects instead of the 8 ohm speaker connects.
So to add to to my wondering, what if it was the other way around, amp 8 ohm fed to 4 ohm speakers. No problem running 8 ohms on a 4 ohm tap I didn't push the amp hard so I figured maybe I'll be alright. I figured running amp 8 ohm to speakers 4 ohm is worse than what I had done. Impedance mismatch would be worse.
Connecting 4-ohm Speakers to an 8-ohm Receiver
Best bet is too know what load your amp can run Playing four 16 ohm speakers at the same time would make an 8 ohm load, which would be safer for most amps but there are not a lot of 16 ohm speakers out there.
I know it gets confusing.
I have a similar situation but not a tube amp. I am confused as to how to connect the two. As long as you remember this, you should be on the safe side, even with a mismatched setup. Thank you much AG.
This can be a good thing if you end up not being shy on power, that is not pushing the amp all the way into clipping. Reversing the mismatch and you could get excessive heat build up in the amp's output and may increase distortion, neither is a good thing. For tube amps anyway.
MelodyMasterJun 13, I didn't know there were recommendations for this - and here I nearly had a stroke the moment I saw it, a panic shut down - for no legit reason I guess other then I thought at the moment "what am I doing to my amp! You will lose some potential power by running 8 ohm speakers on a 4 ohm tap but other than that nothing will be hurt. Newbie here so please forgive me for not knowing the rules yet. This is a new thread about bi-amping. I have a pair of infinity kappa 8. I have a pair of mcintosh mc amps.
How do i hook these up and what do i need to hook these up?
What happens running 4 ohm amp connects to 8 ohm speakers?
Any info would be appreciated. Parallel If the two 8 ohm speakers are wired in parallel and tapped into 4 ohm on the amp isn't that cutting the speakers to 4 ohm and it's all running at 4 ohms? Also what happens if you have two sets of 8 ohm speakers running from a 4 ohm tap running at the same time I have a fisher c set on 4 ohms. To a speaker switcher. Most of the speakers are 8 ohm. I never run them all at the same time. But am I asking for trouble if I have two sets on at a time And what if I run one set of the 8 ohm speakers at the same time as the 4 ohm set They sound ok when I do it but I'm worried I'll blow up the vintage amp If I'm using the 4 ohm tap Is it better to run the two sets of 8 ohm speakers?
Is that better than running one set of 8 ohm speakers? All speakers are rated at an "average" wattage and ohms load, its not set in stone. Depending on the frequency the ohms level will vary somewhat anyway.
Not sure if any harm will be done using ether tap but the distortion levels will go up as the ohms load goes down.
What about if I have 1 meter 94db 8 Ohm speakers. I find them to sound much better on the 4 ohms tap. With 94db being easier to drive? Would this make since. I had some logitech pc speakers and the speakers were 8ohm and also some packard bell which the bass speaker were blown and the packardbell were 4 ohm and i put the speaker out of the logitech into the packardbell 8ohm amp - Packard Bell with 4ohm speaker - Logitech The packard bell had a speaker guard glued to the speaker and the logitech didn't so it also has less interference on the sound but also looks cool because theres no guard.
Sagar Choudhary on February 21, Reply Sir,l have soundstandard ca20 amp. Running a 4-ohm cab from an 8-ohm-rated head would result in excessive current draw, and could damage the amplifier. The higher the sensitivity of a speaker, the louder it will play at a given power level than a less efficient design. We hope this is helpful, but just let us know if you have any more questions!
