RT600i ohm question

jbaker

I've read some where on the net that the tweeter in the RT600i is 8ohm and the woofer/mid is 4ohm. If this is true, doesn't this make the speaker 6ohm? As I doubt it's wired the opposite as 12ohm. If all is true, then I should be switching my receiver down from high to low ohm usage. Any information or truth on this would be great, thanks!

Ok, I just remembered I had a multimeter. So I tested one of my speakers with the multimeter from the 5-way post and it reads somewhere around 3.8 or 3.9 ohms. So my question is now, why are these speakers labeled as 8 ohm?

Don't change the settings on your receiver. Even if they are 4 ohm speakers, keep the receiver setting at 8 ohms.

NOTE: Some Receivers have an impedance selector switch. In most cases we recommend the 8-ohm or more setting. The manufacturer puts them there for UL/CSA approvals as well as easing consumer concerns about driving low impedance loads. These switches step down voltage feed to the power sections which will limit dynamics and overall fidelity. Keep the switch set for 8 ohms regardless of the impedance of your speakers and ensure proper ventilation of the Receiver.

Thanks for the info but I'm glad I tried it out before reading that. My polk towers have never sounded as good as they do, by switching the receiver to low/4 ohm. And it's not just a slight difference, it's huge. Let me explain.

The tweeters now actually sound life like. When a cymbal is hit, it actually sounds like a real cymbal. Before, at the high/8 ohm setting, the tweeters sounded soft and kind of dull. Also, now it sounds like some of the sounds coming from the tweeter are actually in mid-air and not prominent to the tweeter itself. It's not harsh at all and I didn't even need to turn the treble up like I did before.

The midrange is definitely better. Just like the tweeter but more so, the audio sounds like it is mid-air. While doing some test, some of the mid range audio or effects was beautifully diffused around me. This was a big shocked as I didn't expect that at all. I also noticed some sounds that I hadn't noticed before.

As for the bass, it is definitely tighter but also still strong. Again, the bass control was left flat. But I've never really had to turn this up before on these towers. It is almost like I got better dampening response when switched to the low/4 ohm setting.

I would have never guessed that one little switch could have made such a difference. It's literally night and day. Sure, it sounded good before. But now it's like I have much more expensive setup. Granted, what I have isn't cheap but it wasn't thousands of dollars. My wife even noticed the difference. The over system is now very clean, accurate and powerful sounding. And I was going to buy new speakers and possibly new rca cables. I'm of course not buying anything new now.

My setup is the following just in case anyone would like to know...

Yamaha BD-S1900 Blu-ray player (I use for CD's and of course movies)
Yamaha R-S300 Receiver
Polk Audio RT600i towers
Monster Cable Interlink 400 mkII
Monster Cable Z1R speaker wires

Oh and when I was doing my test, I was just testing CD's. I tested some rock/alternative music, which I find overly compressed and not the best source for testing. Really depends on the artist in that area though. But also classical and some black eyed peas (that's the closet thing to rap I have for testing deep bass). I can't wait to go back and rewatch some of my blu-rays now.

Anyway, according to the above article link, I guess it would depend on the components you have or their quality maybe. So I wouldn't just go by that alone. Test your own setup out and see what's best.
