Yeaaaaa

Not gonna lie skip, you sound sort of tipsy sometimes. lol

Also, is it not pronounced "Flex" Audio?

I wish these videos would play on my cell. Howd they sound? I really haven't heard anything about them but bad...

hmph...well, I still didn't see anything that made me want to run and buy one.

What nominal impedance are you running those? Looks like you set your gain with the amp seeing 10 ohms. When the impedence drops those will go up in smoke fast.

Yup.....in those 2 vids...not much going on

I wasnt worrying bout the ohm load.....was just looking at the power the subs was actually seeing....but they are at 2ohm right now

Even if i had it wired too .25 i still would have set the same too about 1200w

So assuming that amp is capable of constant voltage (90V) at a frequency where the woofers are actually a reactive load of 2 ohms you have I = E/R = or 90V/2ohm = 45A P=IE 90V * 45A = 4050W. Ohm's law says it's only 1200W at the one or two frequencies at which the system rises to a 10ohm load.

Hence the failure of setting gains at just some arbitrary frequency. Ideally you should find the frequency at which the sub's reactive load is LEAST, set to that, then you'll know that is the maximum power they'll ever see.

Thank you, Sir.

I started to tell him to do that also, but 40hz is a good spot, man. They'll see more power at or near tuning, but Skip doesn't listen to C&S music 24/7 so they'll get a good range of power.

If he sets for 1200w at tuning (where rise is usually lowest), they'll rarely see that 1200w. Set for 1200 somewhere in the middle and they'll wind up averaging 1200 as long as the source material is varied. The other thing is that we know it's clean; which is most likely a far cry from what most people are going to be feeding them. They'll get 1.5-2k clipped to death from 90% of users.

1,200 clean @ 40hz is fair.

Impedence is least at resonance you say? I had always believed that finding impedence peaks was how we determined resonance.

How do you determine resonance of the alignment when it's already set, or at the very least altered, by the vent?

Maybe I should have said what I always say and that's "at or near tuning." Is at or near tuning going to be the exact lowest spot on the imedance plot? I don't know. I don't do impedance sweeps on every alignment I've ever owned, but I've clamped **** near every box I've had and impedance is pretty f'n low at my intended tuning.
