According to the book, he recorded the finger tap with a Zoom H2 digital recorder and then did an FFT in software to find the frequency.@ barhrecords ... Interesting YouTube link regarding "tapping" the speaker to hear it's resonant frequency!
I found this link to an online audio freq generator ( Tinnitus Treatment Sound Therapy - Tone generator & Tuner | AudioNotch ), and I can listen to his tap on the YouTube video, then plug in the frequency noted into the online generator and I can get close.
It's a bit tough for me to hear the frequency when he taps the larger woofers., just sounds more like a "thud" to me.
That's the problem with the low-bass frequencies: they tend to sound like thud. That's also why (sorry for the soapbox hijack) too much bottom end can destroy a guitar tone in a mix.It's a bit tough for me to hear the frequency when he taps the larger woofers., just sounds more like a "thud" to me.
The first line of my OP states:I'm trying to find the LF resonance of the combination Friedmann HBE + Cali Lead 80s Mix using the filter block between the amplifier and the cab. I hear the most pronounced resonance at 165-167Hz, but this is definitely not the cab resonance? Could somebody tell me how does the "real" cab resonance sound and what is the proper frequency for this cab (Cali Lead 80s Mix) please?
I don't think that will do the trick. Sag is calculated in the power amp simulation; if you turn that off—no sag.
I didn't know that.Cliff told me this would still work as the preamp sag is tied to the power amp. He said if I set the sag value to zero it will disable the preamp sag but the global power amp off only disables the power amp sag.
I really have no desire to irritate you Cliff, but with an FRFR system - Is it not a good idea to know the low res freq of the drivers and plus the cabinet used in the IR when dialing in the Amp Block?The first line of my OP states:
"This post is aimed at those who use a solid-state power amp into a [SIZE=+10]conventional guitar cab."[/SIZE]
I think that is legit; matching the AMP block SPKR page settings to an IR and using FRFR.I really have no desire to irritate you Cliff, but with an FRFR system - Is it not a good idea to know the low res freq of the drivers and plus the cabinet used in the IR when dialing in the Amp Block?
But threads on internet discussion forums tend to go where they go.
I've never really thought of that as a bad thing myself.
Trying to force a discussion to always stay 100% on topic seems sort of futile to me.
That's what I thought. Leaves me confused about how preamp sag would continue working; it's based on power amp sag.
