Polk Speaker and Onkyo 805

Knight770

I as have the Onkyo 805 AVR and its very a First Time with the Onkyo 805 AVR, also Speakers: Tsi-500 Floor Standing, Center-CS10 and Tsi-100, Ok These Speakers all are rated 8 ohms, How that I seen on 805'setup and has seen only options 4 or 6 ohms but no 8 ohms ?

My understanding as I wont put on 4 ohms . Concern will this speakers gets along with 805's 6 ohm ?

Do you have that one ?

The Onkyo TX-SR805 is rated for 6 or 8ohm loudspeakers.

The Onkyo "Dynamic Power" is rated at 4ohms but that doesn't mean you can connect 4ohm loudspeakers.

Niether situation affects you so worry about other stuff.

Set your 805 to 6 ohm and that will take care of both 6&8 ohm speakers. How are you liking your new speakers?

Don't change the switch at all, you'll never know the difference.

I drove my LSi9's (4 ohms and lower) on my Onk805 for a short time. I didn't experience any issues-of course I also didn't tempt fate and turn it up to loud either.

Here's an excerpt from the 805 manual (page 20):

You can connect speakers with an impedance of
between 4 and 16 ohms. If the impedance of any of the
connected speakers is 4 ohms or more but less than 6,
be sure to set the speaker impedance to 4 ohms (see
page 45). If you use speakers with a lower impedance,
and use the amplifier at high volume levels for a long
period of time, the built-in amp protection circuit may
be activated

And Page 45:

4 ohms:
Select if the impedance of any
speaker is 4 ohms or more but
less than 6.

6 ohms:
Select if the impedances of all
speakers are between 6 and
16 ohms.

How did they sound?

mmadden28

They sounded fine. I definately could tell the difference between them and the RTi12s-much much smoother/richer sounding. Of course this was earlier in my audio journey, so I didn't have as much of an ear for what audio nervana sounded like then (still don't for 2 ch. but I'm def. getting closer). Not to mention the room they were in was definately not a match (way too big, etc).

Got em Back, Since Busy haven't regret take em a look at those posted it and Thanks about the Page45 that will do with the 6 ohms auto up to 16 ohms a support.
My A would like to know if you personally have the Onkyo 805 A/V If Yes so then I 'm that really frustrate doing w/ the Onkyo 805 manual as not fully understood the hz between DB Sound, as I did letting Audessy to do calibrate all of My Polk speakers and the sound that a still in Low even increase in volume,not acceptable satisfy low sound then Onkyo A/V shutdown turn to stanby due the overheating. Not so helpful Can you one if u have then I a get the Email picture of My Onkyo 805 Speaker setting , things up and email you and your to help me your a suggestion .

You must be still drunk from last night. What in the hell are you talking about?

For mass-market avr's, always leave the ohm switch set to 8. Regardless of your speakers. See posts 2 & 4.

Are you by chance using some kind of online language translator? What is your native language? What you wrote is very difficult to understand.

Alost sounds like you're saying that you ran throught he Audessy auto setup and you thing the volume is unacceptable low even if you turn the volume up. Is that right?

Something tells me that if it really didn't make any difference, the manufacturer's wouldn't put the extra money into adding the option.

If you're using an external amp, the option is irrelevant, but if using the AVR's amp, I believe the setting changes something with respect to current limiting circuitry in the AVR amp or something like that. I doubt its just fluff.

I would have to guess that in certain situations you'd be better off adjusting the switch. For instance...if you were to run some 4 ohm speakers, you would probably be better off flipping the switch to 4 ohms rather than leaving it at 8 ohms. I'm sure the manufacturers don't put those switches there just for the hell of it.

Flipping the switch to 4 ohm mode actually limits the available current from the amp section of the AVR, so the actual power output is never used. If you were running 4ohm speakers, you would probably be better off with something designed for such a difficult load. Again, I would leave the switch as is, just as Dorokusai said in an earlier post.

That's true, a lot of the AVR's out there that are "4 ohm certified" aren't really designed to run 4 ohm loads full time, but they're still capable of it. You just can't crank it for long periods of time. You're better off in all reality just not running 4 ohm speakers on most AVR's though.

I would imagine that given a situation where you were going to hook up 4 ohm speakers you would still want to flip the switch to 4 ohms. It might not be recommended to even use speakers with a 4 ohm load...but people are still going to do it.

Basically what it comes down to though...if you're running speakers with a 4 ohm load...you need to upgrade to some external amps.

and the sound that a still in Low even increase in volume,not acceptable

Go into the setup menu and increase the level. Start at +6 on each channel and then listen to something and play with the volume knob and make adjustments that work for your room.

I do like the Polk Speaker due their warm sound speaker !

Knight, sorry I also had a little trouble with this post. Just to make sure, have the Onk 805 set in the 6 ohm setting. Try re running Audessy, it does make errors sometimes. Also make sure it does not pick up other sounds, refrigerator turning on, car horns outside, kids playing, dog barking etc.etc.
Also how much room are you giving the Onk for air circulation/cooling? There were a lot of reports early on about the 805 over heating, but also many who said with proper space for cooling they had no problem. How high are you turning up the volume to get satisfactory results for you? I would not think your speakers are over taxing the Onk in any way, make sure you have good solid connections with your speaker wires on both ends and no stray strands are shorting + and - together. Also make sure the jumper on the binding post at the back of the speaker is in place and tight.

My 805 drives Lsi 25 and LsiFx just fine. But I set the switch to 4 Ohm just to be safe.
The receiver runs a lot cooler since I flip the switch.
