Considering new A/V receiver

[majac777]

Hello,

I have two new AxiomAudio M80 front R/L floorstanding speakers (4-ohms) currently powered by a Harmon Kardon AVR25II (old). I'm considering replacing the HK with the newer Onkyo SR805, which the specs say is "Certified 4 ohm Performance". What actually is meant by that statement?

Also, the support person at Onkyo said that if I use 4 ohm front speakers, that I'll need to use 4 ohm speakers "all the way around". He had to ask someone else to tell me this. My question is: if I later add a center-channel speakers, rear speakers, and a subwoofer...would they ALL have the be 4 ohm speakers?

And if so, why is that?

Many thanks,
Majac777 (Andy)

NO, they don't all have to be 4 ohm. That would put more of a load on the receiver. The 805 is designed to be able to handle speakers with a 4 ohm load.

Thank you for your reply..

Using Onkyo is new to me, as I've been using Harmon K. for years. I can already see that the difference in quality telephone support between the two companies is like night vs. day. H Kardon has always had superb support from my point of view.

That Onkyo rep doesn't know what they are talking about, 4 ohm speakers all arround is never a good "recommendation".

Thank you all for your suggestions.
Tomorrow I'll be setting up the Onkyo sr805 I bought today to use with the Axiom M80 R/L front speakers. I'm planning on picking up Boston Acoutics XB6 powered subwoofer tomorrow.

Here's a question: how difficult is it to build your own center-channel speaker for a home-theater? I don't know that much about audio technology, but I think that it probably would not be that hard.

What do think?

Well I would suggest against building your own center since you have already purchased your front two speakers unless you can get the same tweeter/drivers for the build from Axiom to keep timbre the same. So my suggestion would be buy a center from Axiom preferably one in the same series as your mains.

As far as building a speaker goes. It can be as easy or as hard as you want it to be, but taking short cuts will only let you end up with a substandard specimen which would likely be lower quality than something you can buy. Keep in mind that if it was very easy to build a set of speakers wouldn't everyone do it? I am currently in the process of attempting to build a very high quality designed speaker and even with the guidance of someone with large quantities of experience it has not been easy and I have barely entered the design phase. Although I will say that the method I am pursuing is far more complicated than typical designs.

i think it's best you buy the matching center speaker for your left and right speakers, so you can get a matching sound from the front speakers.

The front soundstage being timbre matched is pretty important to me personally but not a HT breaker. It often depends on how radically different the loudspeakers are in actual build. That being said, I would stick with was was mentioned previously, keep them matched. The rear channels are less critical in a surround format.

We often get questions on the Polk forum about matching vintage speakers with newer speakers and we have some suggestions set up that seem to be working well for those folks. I haven't heard anyone come back pissed off, so I figure that's a good thing.
