Bi-wiring a Yamaha Z9 & Energy Veritas V2.3i

[EgoZoogo]

I haven’t built a nice stereo system in many years and I could please use some help!
I just purchased:

1 Yamaha RX-Z9 receiver 170-250 watts max
2 Energy Veritas V2.3i speakers 200 watts max
4 Energy Veritas V2.0 ceiling
1 Energy Veritas V2.0ci center channel 150 watts max
2 Yamaha YST-SW1500 subs 1,000 watts each

I still breaking in the speakers (80 Hrs to go) and I’m a little confused about how to hookup the front speakers and subs, the front speakers have bi-wires including the center channel. Is it helpful to run another wire to the receivers “B” speaker terminal? And run the fronts A+B?

Welcome aboard. Nice gear!

Speaker Break in is a bit of a misnomer. Beyond 20hrs or so for the bass drivers there really isn't any other "Breakin" occurring. Tweets especially don't break in.

As for biwiring, there is little to no benefit in doing this. I would advice picking a high quality single wire solution of 12 gauge or lower, perhaps from one of the vendors we have tested and recommend.

Here is a list of cable vendors we endorse and have special purchase deals with for our readers:

"VERY NICE" system. Quality cables and interconnects as Gene mentioned will do the trick.

Yes, welcome aboard.
Your speakers were ready after a few strokes, so go ahead and just enjoy them, don't agonize over them

Use 12 ga or 14 ga wire for the speakers. Short runs you can use even 16ga. Long ones, use 12ga. Simple, unless you also want the pleasure of seeing your cables as an art object
No need to bi-wiring.
Don't do the either of the method you proposed

Welcome to the forum. You've got some really nice equipment there.

Upon looking at the back of the RX-Z9, there are two different hookups for the sub. One has a single rca, and the other has a left and right rca for the subwoofer. You should be able to hook up the subs to each left and right with a standard single rca cable (one for each sub). Let the receiver do the bass management. Don't run your towers through the sub. Here's the rear panel:
http://www.yamaha.com/yec/products/receivers/RXZ9_back.htm

That receiver has 9 internal amps. Seeing how you're using 7 of them now, I don't think using the two "presence channel" amps would benefit your towers. I'm not one to push for using a receiver's "left over" internal amps to "bi amp" towers. I'd rather see people purchase a separate quality two channel amp to power demanding towers.

You may experience a bit more headroom if you used the "B" amps to power the top end of your towers, and "A" to power the bottom end (or vice versa), but only do that in stereo mode. This is generally not recommended as it taxes your unit and could cause overheating issues which could lead to damage.

The only drivers that need broken in are the woofers/subs. Manufacturers suggest 20 hours. That's it. Enjoy your new system!

!

Does this receiver have amp inputs too, not just pre amp out?

Where is the single one?

Absolutely. There are 7x170W, but the Presence channels are only 2x50W.

You may experience a bit more headroom if you used the "B" amps to power the top end of your towers, and "A" to power the bottom end (or vice versa), but only do that in stereo mode. This is generally not recommended as it taxes your unit and could cause overheating issues which could lead to damage.

I'm not sure that you are correct, although it's possible we are referring to different things here. I have my own speakers biwired (yes, yes, I know), and use the Speaker A and B terminals to do so, rather than splicing twice the number of wires into half the number of terminals, but this is done at the recommendation of the manual. As far as I am aware, both the A and B terminals still use the same number of amps (two, for Front Left and Front Right) as using only the A or B terminals; the extra speaker terminals are purely for ease of connectivity.

20 hrs of break in? So that's all that is needed?

At the very most, and only in the bass drivers. We will be writing an article on this topic shortly. This myth has been living for too long. Its time to put some prespective on it.

Gene,
Bless you for doing your part to stop the tide of BS that currently seems to swamp voices of reason and logic in the world of mid/hi-fi.

Quite a coincidence that many claimed speaker break in times exceed the return window for the product

 

[jaxvon]

I would have to say that after X hours of playback, all drivers, including tweeters change (break-in), as this is a result of mechanical stress, but I think the point that I HOPE you're going to make is that these changes in the tweeter are so minute that it doesn't make an audible difference.

Is the hi end immune? They should get equal time, at least

What kind of research behind it? Will you cite them? Some are interested

Good point, I agree with you 100%

The article is completed. Just going through final peer review now. There are plenty of references, measurements, etc to prove our position. Stay tuned...

Here is the article on Speaker Break In. I hope this helps demistify some of the misconceptions surrounding this topic.

I think he knows a few things about speakers and drivers

Huh? I'm completely confused by your post Mtry. I agree with the link though..

Great article. Thought you would make a new thread on it, but I guess it can still be.

Same conclusions and measurements as Richard Pierce done some time back
