Hi all, I am trying to look every where as I have lost my manual. I can't seem to find it on Yamaha's website either. I am planning on the purchase of the M80's. So I want to know if my receiver supports 4ohm speakers?

The manual for the HTR6090( I would think the 6190 is nearly the same ) has a spec:

• Dynamic Power (IHF)8/6/4/2Ω .....................155/195/250/330 W

So I guess it should work with a 4 ohm load but usually a receiver that works at lower resistance will have those specs published more like:

• Minimum RMS Output Power for Front, Center, Surround,
Surround back
20 Hz to 20 kHz, 0.04% THD, 8 Ω .................................... 120 W


Buy the M80s and if the receiver doesn't work out, you now have a great reason to upgrade the AVR

Frosti, welcome. This point comes up frequently and you can look at the Sherwood 770 thread for a relevant discussion by Alan and others. The answer is that no, it doesn't "officially" support 4ohm speakers because the lab torture testing that would be necessary wasn't or couldn't be done. Nevertheless, the 6190 wouldn't know that it was connected to speakers that were rated at 4ohms and there's a high probability that it could supply the voltage and current necessary(the M80s are slightly above average in sensitivity and so require less, not more power)unless played unusually loud and long.

I looked in the manual. It appears there is 2 settings in the menu.
it is 8ohm and 6 ohm. under the chart, it looks like if set to 6ohm. The fronts impedance is min 4ohms, while all other channels' min impedance is 6ohm. So it looks like the receiver does work.

I have just bought this receiver less than a month, so I will not be upgrading anytime soon. This receiver is same as the RX-V1800.

So is it ok to mix impedance on speakers? Would it be suggested to buy the M60 instead? My room is about 17ft long x 12 ft. I have just bought the M22 for my surrounds. I am planning on buying the M80 for fronts and the VP150 as center along with another set of M3 as my surround backs.

I just want to make sure my receiver will be able to handle it.

any suggestions?

Disregard the lower impedance setting described in the manual. Always leave it set at 8ohms regardless of the impedance rating of the speakers used. The lower setting is simply a safety precaution which makes overheating less likely. It does this by lowering the maximum voltage which the amplifier can supply, and because of Ohm's Law, when the available voltage is lower, so is the current and power lower. So, although the risk of overheating and fire is reduced, so is the maximum performance capability.

Yes, there's no problem with using speakers that have different impedance ratings. The M60s should be fine in a room of that size, but if you really want the M80s you shouldn't hesitate because of the 6190. It isn't possible to be "sure" that an amplifier, regardless of whether it's in a receiver or separate, will handle a particular set of speakers, source materials, loudness levels used, etc., until it's actually tried, but folks have been using the M80s and other 4ohm rated speakers for years with similar receivers without a problem.

Since you want to use direct radiating speakers for surrounds, it's suggested that the M2s would match your other Axioms better as back surrounds than the M3s would.

i was doing some reading and it appears their will be risk of over heating and fire if driving these speakers too hard. However, what is consider too hard?

I decided to go with direct drives for surrounds as I have had some Dipole surrounds....I don't like them. The sound specially bad when I have 7 channel music going.

Here is the brochure. I doubt very much that you will push this receiver anywhere close to its limits. How big is your room and how far away from your speakers will you be sitting?

ok..I did some actual measurements. My room is 18'x13.5' I will be sitting about 13feet from the speaker.

That tells me that you will most likely be listening with a nominal power of a watt or so with 64W peaks. This is nowhere close to the full power of the amp.

Frost, don't put the Axiom quadpolar Q's series in the same category as other manufacturers bi or dipole speakers, they are not dipole speakers. They have 4 drivers that fire in phase, totally different. The Q's are awesome for 7 channel music listening and are the best in the industry for HT applications.

Direct radiating speakers will not give you the same experience as speakers designed to simulate theaters lined with speakers.
