Default Help with crossover setup for my new Engergy Speakers?

Hello,
I am about to receive an energy surround system to be powered by a new Yamaha RX-V663 receiver. This will be my first surround system setup so any advice I could get would be greatly appreciated!

I am trying to get an idea of what to initially set the crossovers on the speakers. I believe the key spec is the Frequency Response but I am also including the "Crossover point" as that sounds like it would be relevant?

Here are the specs:

Mains: Energy C-300: Freq Resp: 40Hz-20kHz +/- 3 dB; Crossover Point: 2.6kHz
Center: Energy C-C50: Freq Resp: 60Hz-20kHz +/- 3 dB; Cross. Pt.: 2.2kHz
Surrounds: Energy C-50: Freq Resp: 65Hz-20kHz +/- 3 dB; Cross. Pt.: 2.9kHz
Sub: Energy EWS-8: Freq Resp: 3Hz-150Hz +/- 3dB

Please let me know if you would like any other specs as I would be happy to provide them!

Thank you!!

A good starting point for the cross-over setting on the receiver is 80Hz and the same for the subwoofer though setting the sub's cross-over at 100Hz is also good. This way you let the subwoofer handle all the low frequencies below 100Hz and the rest of the system will take the rest from 80Hz to 20Khz.

You can play around with the setting from there. I see your mains can go down to 40Hz and you can let them handle less than 80Hz (down to 40Hz) if you want but it is recommended to let the sub do what it does best.

Thanks for the input. I know the crossover setting for the sub is actually located on the sub. But for the speakers it is handled on the receiver, correct? Furthermore, can the speakers be adjusted individually so that I could set my mains a bit lower, to say, 60hz with the rest at 80hz?

In the Audio Setup portion of the menu is where you set that up. You can set the cross-over frequency to the mains differently than the center and surrounds. I suggest starting them at 80 and listen to a piece of music or video, back up and play it again a few times until you are familiar with that sound, then change the cross-over point.

Another thing to do when you are using a sub is to set your speaker size to small in the menu.

One more thing.. most speakers require a bit of "break-in" time.. usually a few hours of low to medium volume playtime.. refer to your manual to see what they recommend of contact the manufacturer. I found this was the case with my speakers.. they sounded very harsh and almost like a tin can when I first powered them up.

Ok wow thanks for the advice. That should really help when I get them all hooked up. The speakers just arrived and I unwrapped them all.. BEAUTIFUL! Now I'm just anxiously awaiting the receiver and sub and then I'm set!!

I'd recommend 100hz to keep the other speakers as clean as possible. But try out 80 too.

You can always use the towers at full range during stereo playback.

i know THX standards say 80hz. but my sats and center don't go below 110hz so from a logical standpoint it doesn't make sense to set the crossover to 80hz. so i set the crossover on all the speakers to the next closest point which is 120hz. i also read somewhere that u don't want to create a gap. LIKE BOSE. example: setting your mains & center to 100hz then your sub to 80hz. creating a 20hz hole or gap. but i'm still learning and u guys have been a great help.

I agree with your theory. An overlap would be OK, just not a gap. At least that is how I understand it.. if the cross-over and sub was set to 80Hz for your mains but the speaker's low end is 110Hz, then you'll lose that 30Hz span between 80 and 110.

I would set the sub at 120 and speaker cross-over at 110, if it was mine and then adjust from there.

Ok this is making sense. Logically you wouldn't want to create a gap which would result in a loss of part of the final audio output. I did talk to an Energy tech guy and he suggested putting the speakers in the "small" setting because if lower frequencies go to all speakers, the result is a "muddy" sound.

I will play around with the settings once I get everything arranged correctly in my living room. I would think a small overlap would be acceptable. Especially with the mains in my case which are rated at going pretty low (40hz).

This stuff can be confusing bbut once you get it... it makes sense

Small is the recommended size setting for speakers when using a subwoofer.

So is the small and large setting independant of setting a crossover limit as well or does the small setting override any crossover setting on the receiver?

The small setting works in conjunction with the crossover settings. If you set large, the lower limit for the speakers "should" go lower.. down to roughly 20Hz or so.

As far as overriding, I am not sure. It's really easy to reset the numbers if they do change though.

The "Large" setting just tells the speakers marked 'Large' to ignore the crossover and play full range.
