I just bought your intimus hybrid 4T system, and I realized that the tower speakers have a 6 ohm impedance while the center channel and the surround speakers have an 8 ohm impedance. My reciever is a Pioneer VSX-1019AH-K and it has a setting that allows you to chose between 6 ohm speakers and 8 ohm speakers. which setting do I chose since the speakers are a mix of the 2? You cannot specify which channels get which impedance. The setting applies to all channels.

 Thanks,

Anthony

For that receiver you want to use the 8 ohm setting.  Using the 6 ohm setting will likely enable protection circuits that will actually limit the amount of power that the 1019 dishes out.  You don't have to worry about harming the receiver or the speaker with the 8 ohm setting though.

Hi Jason,

I am going to order the 5T & 5C next week and I have a similar question. I have Pioneer VSX 9040TXH which also has the option of 6 or 8 ohms. Should I use 6 or 8? I will keep my current Celestion surround speaker for effect, and Jamo Sub 300 as sub-woofer for the 5.1 setup.

 

Thanks.

I'd go with the 8 ohm setting for that receiver too.

Hi Jason,

Thanks. I have been testing my 5T & 5C for the 3rd day…

Jason, you are such a dedicated Aperion employee working on a Saturday, or it is coming up on performance review time!  No, I think it is the first option.

 

Cheers

Ha well in all honesty I originally posted the above to the wrong thread when I was "on the clock", so I was just correcting my mistake. 

However, you can feel free to continue to think of me as a supremely motivated and dedicated employee, I won't mind.   [8-|]

How will having the receiver set at 8 ohm for a 6 ohm speaker affect the sound quality?

It will depend on the receiver, I would recommend trying both settings to see if you hear a difference.

I'm very new to this and just trying to understand everything to make an educated purchase and not spend a couple grand on something that I won't like so bear with me on these questions, which some may seem stupid.

 

If the 4B bookshelf speakers and 4C center channel were designed to have an impedance of 8 ohm, why were the 4T tower speakers designed around 6 ohm impedance?  In the example given in the OP there is only an option for all 8 ohm or all 6 ohm. Can 8 ohm speakers be powered at 6 ohm?  Are there receivers that can detect different impedance in different channels?

Maiden,

This is a tricky subject. It involves ohms law, varying frequency inpacting impedence, and many other factors, most of which you probably don't care about (or maybe you do?). Let's see if we can make this simple……

To make a long story short, most amplifiers will handle the 6 ohm speakers just fine set at the 8 ohm setting. Usually, when setting an amp at 4 ohms, it adds resistance so that the amp "sees" it as being 8 ohm to avoid overheating. The resulting outcome is less volume. Keep in mind….not all do this, some may be designed to run the lower impedence without employing such "tricks". 

Going back to my car audio days, amp designs are all over the place. Some amps are designed to be used at lower impedences, but not at face value. I have a monoblock amp driving my dual subs. The rating is: 220 watts RMS x 1 at 4 ohms (400 watts RMS x 1 at 2 ohms). In the old days, this is how people would cheat in car audio competitions. The drawback to this is that you need more current (technically, double).

Wow! half the impedence, and almost double the power (there is that damn ohms law crap)!!! So, I run my 2, 4 ohm 10" subs in parallel to get the 2 ohm load, and double the power. Versus. wiring in series, which would double the impedence to 8 ohm, and would half the power. But, I need twice as much current…..Oy….

Now this is totally different than most home amplifiers, that are rated at 8 ohms. Car audio does that so that you can get into comptetions at the rated power (the 220 watt), but yet actually get 400 watts of actual power.

So, taken ohms law into consideration, if your speakers are 6 ohm, and you run at the 8 ohm setting, you should get more power, right? Well….maybe yes and maybe no. Most speakers are rated at "nominal" impedence. In layman's terms, this is an "average". But again, frequency impacts this, as well as other factors such as speaker length.

I am sure Hicks could get more technical than that if you want….I have not touched ohms law in years. But his advice is solid. Just set it at 8, and let er rip. The last thing you want to do is get paralysis from overanalysis. I am wayyyyyyyyy to guilty of doing that myself.

I know I asked the same question with my Onkyo 805. It runs just just fine at 8 ohms, as I am sure yours will. I asked the question, as I did not want to cook my Onkyo. Belive me, it gets warm enough on its own (btw…the onkyo heat issue is a bit blown out of proportion). Heat is a byproduct of power.

Let us know how it goes! You will love your Aperions!

BTW…..I am doing this all from memory. I have not been into the tech stuff in well over 15 years. If my info is not accurate, let me know and I will pull this post down.

Scottie,

 

Thanks for the educated, informative response.  This definitely helps!

Scottie is pretty on the money, I would just stress the point that what we term the impedance of a speaker is in fact an average value and the reality is that a speaker's impedance will vary greatly depending upon the frequencies that it is producing.  A speaker that averages 6 ohms across it's impedance range does not present much more of a load to a receiver than an "8 ohm" speaker.  It is really only when you get to a speaker labeled as 4 ohms that you need to concern yourself with having an amp that is stable enough to drive it. 

As for why we design some speakers to be 6 ohms and others to be 8, we don't design our speakers to be a particular impedance.  We design them for sound first and foremost, then once we have gotten the sound that we desire from the speaker we take an impedance reading.  As long as the speaker's average impedance is above 4 ohms, then we go to production.  So really it's a consequence of getting the sound we want that causes some of our speakers to have different impedance values.  Sometimes I wish we just called them all 6 or 8 ohm since it really doesn't make that much of a difference, but we just aren't that type of company.  [8-|]

Just let me know if you have any other questions, it's really no bother, thanks!
