crossover question

[bigbassdave]

I just ran the EZSET EQ on my 635 and for the most part it sounds awesome, but I noticed it set the sub's crossover to 120 hz. Does that seem high??

Yes, that seems too high. 120 for all of them? Can you manually set it and run it again and see what it does?

 

[bigbassdave]

just 120 for sub the rest are all different and yes i can manually adjust. what do you think i should have sub set on?

 

[j_garcia]

80Hz is usually a good place to start, but if the other speaker's crossover points seem fine, you might even try 60Hz (if available). 120Hz will allow the sub to play high enough to be localized.

my surrounds are set at 40 hz does that sound low? they sound good to me though just the sub sounds like it needs tweaking. I will try 80 hz on the sub.

 

[bigbassdave]

the are set as follows:
L/R: 40
Center: 80
All surrounds: 40
LFE: 80 (ezseteq put this at 120 but i switched to 80)

they sound good to me though just the sub sounds like it needs tweaking. I will try 80 hz on the sub.

I'd try 60Hz on the sub.

 

[j_garcia]

If it set the mains to 40Hz, I'd try 60Hz also. That does seem low for the surrounds, but if they can handle it, then so be it.

 

[bigbassdave]

the specs on my surrounds are
58Hz – 20kHz
52Hz – 40kHz (– 6dB)

so should I change them to 60 or should I just trust the receiver's ezset? They sound fine to me now set at 40.

 

[j_garcia]

Try both, leave them on whichever sounds best. My guess is you probably won't hear too much difference in the surrounds between 40 and 60.

thanks for the help fellas I think its just about dialed in now

It sounds to me like the receiver allows you to set the low pass filter for the subwoofer and different high pass filters for each channel. That is unlike most receivers with a global xover for all channels where the one xover frequency applies to all channels and you are setting the high pass filter for those channels.

It probably set the low pass for the LFE channel to 120 because that is the highest allowed frequency in that channel. If you change it to 80, then you will lose some of the signal for those few discs where there is LFE content greater than 80 Hz.
