some settings for my Harmon receiver......

Hi all,
I have:
Harman 325
JBL N38 Tower speakers
JBL N 26's and the satalite 24's.
Velodyne 10" sub


1. Do i set my sub to "SUB (LFE)" or "SUB LFE + L/R" on my receiver?
Which will sound better?
I have also been told to set all my speakers to "small" even though my tower speakers are pretty big.

2. What do i set my X-over to on my speakers and sub?
Someone told me to set them ALL to 80 HZ. All my speakers are diffrent sizes...not sure if that matters....so i still set them all to 80HZ?
What do i set my Velodyne sub to? 80hz also?

3. I have a choice of "global" or "individial" for my sub...i only want my system for movies....so i'm safe to assume i set it to "global"?

Thanks everyone in advance.

Someone told me to set the speakers to 60HZ, so i set all 5 speakers to 60 HZ.
They also told me to set the sub as hight as it will go, so i put it to 200HZ.

Any thoughts or opinions?


also from my last question....."SUB (LFE)" or "SUB LFE + L/R" on my receiver

I set the speakers to SMALL so i cannot choose the above...i can only choose it if i set the speakers to LARGE.

I have this question as well.

I have the HK 525 and a couple S310's as fronts with an SVS 25-31pci sub.

It seems like such a waste to have the fronts set as small when they're probably very capable of handling some of the lower frequencies. Similarly, I don't know if setting Sub LFE + L/R to on will do anything wierd to the sound. I'd really like for there to be a formulaic answer to this question, but it's probably a "listen for yourself, see if you like it" kind of situation.

I'll be watching this thread...

So 60HZ instead of 80HZ and also my sub at 200HZ?

Anyone

Thanks in advance guys.

Set your mains at 80hz, that should be good. Set your subwoofer to maximum on the crossover, and use the one built in to the receiver to control the bass frequency.

Do you have a crossover adjustment(other than volume) on the receiver?? If so I'd say set it around 60hz. Try a little higher, but you amy start getting male vocals comin through your sub.

So set my speakers at 80HZ and not 60HZ?

Also the sub setting is on my receiver....200HZ. So i should keep it at 200HZ?....your saying put the sub to 60HZ?
Yikes now i'm confused on what to do lol.

Someone told me NOT to use the x-over on the back of the sub.
Just use the volume control and turn the x-over on the sub to off so its not being used.

The setup doc of my SVS clearly states that the crossover on the Sub should be disabled (which is likely 200Hz on your sub, if there's not a switch removing it altogether) when you have a Receiver that will be peforming Bass Management. By turning the Sub on in the receiver, you're enabling the receivers crossover for that channel. 200Hz is way too high for your Sub I believe. You want your Sub to concentrate on the lower Hz, so I think a setting of about 60Hz is probably correct.

What I'm still not clear on, is what the receiver does with bass when you set your mains as Large and set LFE Sub + L/R.

I don't know whether it would be ideal for the fronts to take care of the somewhat low bass, and leave the Sub to the really low bass, or if bass frequency overlap between the mains and the sub is desired (and even possible, though I think I've read that it is).

If your sub has a variable crossover, open it wide up - as in the knob on the sub itself.

If your sub has an "LFE" input, use that. It will skip the crossover circuitry in the sub.

When selecting your bass crossover levels, keep in mind that you are also letting the receiver's amps work without bass, which should allow for more headroom and better dynamics.

Lok at the specs for low frequency rolloff on all of your speakers. If the speakers roll off at, say, 60 Hz, set the crossover above that, like 80. Global at 80 means everything is crossed at 80, whereas individual lets you spec different cutoffs for different sets of speakers, depending on their rollof point. Bokshelves may be best at 80 or 100, when towers would be OK with 40 or 60. But 40hz really is pretty low, and to play loud it would be best to free up the towers from that load and let the sub do it.

LFE + LR usually means you are running the mains large and the sub gets LFE and whatever bass is recorded in the L/R, resulting in some duplication of effort. Measure to see the effect, but I wouldn't use it. My preference.



Always experiment to see what's best. Measure if you can, so you can see what you are hearing.

You call that a knife?

Ya, my sub x-over is turned off on the back of my sub.

I'm just using my Harmon 325 for all the settings.

So all 5 speakers at 80HZ and my Velodyne sub at 60HZ....


Why did someone tell me to set it at 200HZ, thats a pretty big diffrence from 60HZ, doh!

Jay Blanchard

Wouldn't setting your crossover at 80Hz for the mains/surrounds and setting the Sub crossover (in receiver, not on Sub) at 60Hz result in a gap between 60 and 80Hz?
