That's not really a question anyone can give you a definite yes or no for. I suggest you play with the distance and with toeing them in and see what sounds best to you.

Are you going to try bi-amping them?

Ya I did bi amp them, Also i have the receiver set at

80hz for the fronts
150hz for center
80hz for surrounds
and 120hz lpf of lfe

Do these look right?

It looks kind of high for the center, but I don't know what kind of frequency range your center speaker has. If you're looking for an upgrade to your system, one of the biggest you can make is to replace your center with a Polk CS1 or CS2 to match your Monitor 60s.

[ryandubbz]

which would better match cs1 or cs2? Also its a yamaha entry level htib center speaker, do you think i should change the 150 to something lower like 80 for all of them?

Like these speakers http://www.yamaha.com/yec/products/p...2&CTID=5000800

[Steve]

If it was my system, I would go with the CS2 since it's the bigger/beefier speaker. Polk says either is a good match for your Monitor 60s. Also, if you prefer, it's my understanding that the CS10 and CS20 are newer models, but still basically the same as the CS1 and CS2, and would still be a good match with your Monitor 60s.

No, don't change to 80. The 150 was set when Audyssey measured the speaker in your room. I agree that it is high, but when measured that is all it could do.

Your front speakers should be timbre matched. This means that everything should sound the same in each. Having a Yamaha center with Polk mains is a bad idea. You should upgrade.

Ya I plan on upgrading the center and the surrounds, but just upgraded the fronts so hopefully soon i will get the center. So i should un biamp the fronts? so i have more power per speaker? Do i have to re run the audessy calibration then after i do this?

Anytime you make a change to your set up you should run the calibration again.

That includes moving a speaker, changing the direction the speaker is pointed, replacing a speaker, etc.

That's not correct. I've had Audyssey measure the frequency range of speakers incorrectly before. It almost always sets my center at 120, but it can go down to 85, so I always manually change the crossover for my speakers to match their actual frequency range, or my preferred crossover level. There's no good reason to leave it where Audyssey sets it, if it happens to set it incorrectly. Audyssey is just a good starting point for the total calibration process for your speakers.

Audyssey correctly measured your speaker IN YOUR ROOM. What the speaker does (or what the manufacturer claims) does not translate to your room. By turning it down, you not only lose the corrections below the Audyssey discovered value, but you potentially have a hole in your sound (if the speaker can't play below 150hz, why force it).

One thing to note about bi-amping with your receiver is doing so will reduce the power per channel for all channels. The Onkyo 706 will also get much hotter doing so. The drop off is significant. You will get less power to the front speakers even though 2 channels are dedicated to them and the surrounds will surely get less power.

The bench tests on the 706 show 5 channels gives about 75 watts per channel. When you bump it up to 7 channels (which bi-amping effectively does) the power per channel drops to around 28 watts.

Overall you will decrease the performance of your set up if you bi-amp with the receiver.

As far as your center channel is concerned I suggest the CS1 to match your 60s.

I seen that before as well... I'm convinced it is a typo since the x05 series didn't drop off that much. I mean, that dropoff is HUGE...

I hope it's a typo too but the xx7 series seems to be getting the same type of drop off. The xx5 was a beast series but after that they seem to have lost their power.

Really? That stinks. I was a huge Onkyo fan (I have a 705) due to the cost vs features they provided. Now, with the power issues and the less capable Audyssey EQ, I'm not so sure what I'll get next time....
