Shoot for all I know the things might not be playing anything below 80 Hz. I just plugged those values into my DSP since that was what GZ listed.
I will say that I've got some Kenwood 6.5s in one of my trucks that do seem to play that low. The reason I say that is they sounded pretty muddy at a 50 Hz setting. I bumped up the filter to 70 and they sounded a lot cleaner.
All of this is just my tinkering. I ain't got enough sense to lick myself without falling off the couch and banging my head on the coffee table. My solution was to sell the table.

When do installed the gz , I also thought the crossover was to be set at 50hz I put that info out thereon this site and was told that the 50hz was for a sub
I reread the info on the GZ and I sid read it wrong. It dis state 50 Hz was for a sub woffer.
I have the crossover at at 90. With 280w sent to them. Loud and clear with no cutting out

The rule of thump I was told was 3x the speakers Fs rating
FS
This parameter is the free-air resonant frequency of a speaker. Simply stated, it is the point at which the weight of the moving parts of the speaker becomes balanced with the force of the speaker suspension when in motion. If you’ve ever seen a piece of string start humming uncontrollably in the wind, you have seen the effect of reaching a resonant frequency. It is important to know this information so that you can prevent your enclosure from ‘ringing’. With a loudspeaker, the mass of the moving parts, and the stiffness of the suspension (surround and spider) are the key elements that affect the resonant frequency. As a general rule of thumb, a lower Fs indicates a woofer that would be better for low-frequency reproduction than a woofer with a higher Fs. This is not always the case though, because other parameters affect the ultimate performance as well.
