4Ω speakers useable with 6Ω tuner?

AI Thread Summary
Using 4Ω speakers with a 6Ω tuner can cause damage to the tuner’s output transistors, especially if it is a solid-state receiver. Solid-state amplifiers prefer higher impedance loads, while tube amps can handle lower impedances better. A potential solution is to wire additional 4Ω speakers in series to create an 8Ω load, or to use a passive resistive load in series, although sound quality may vary. The safest and most effective option is to purchase 8Ω speakers that match the amplifier's power rating. Overall, opting for 8Ω speakers is recommended for compatibility and performance.

I just got a new home theater tuner with outputs that say 6Ω, but the speakers I have are 4Ω. Can these speakers be used with this tuner?
 
Engineering news on Phys.org
If the tuner is solid-state (I assume it is, and it's actually a receiver, combining the functions of a tuner and an integrated amplifier), you have an impedance mismatch that might wreck the output transistors. Tube-driven amps can handle low-impedance loads pretty well, but solid-state amps can be pretty touchy about that. Solid-state amps are much happier with loads that are higher-impedance than their nominal rating.
 
thank you for replying. does this mean that there is no solution to make these speakers work with this tuner?
 
If you can get another pair of 4 ohm speakers AND wire them in series, you'll have an 8 ohm load on each channel and your output transistors will be happy. You could also wire a passive resistive load in series with each of those speakers, though I can't vouch for the sound quality. Your best bet is to get a pair of decent 8 ohm speakers (most common impedance) that are rated to handle the output power of the amp.

So, speaker ohms can be higher, got it. I'll get some 8 ohm'ers then, thanks!
 
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
