Re: Max Voltage during Live Sound???

And the transients are what drive me nuts. In live sound the kick drum is mostly the one channel that has those transients. The bass channel sometimes also.

I hate that I have to lower the overall volume just to deal with those transients.

Re: Max Voltage during Live Sound???

Yup, sub amp all the way up. And it never occurred to me about the whole average vs peak being a difference of 6 db's which is also half the voltage and 1/4 of the watts. All depends on how one looks at things. Being that we're concerned with displacement killing the sub drivers moreso than any type...

Re: Max Voltage during Live Sound???

So then say a live mix has 12 db of dynamic range - wouldn't this justify compressing the entire mix by roughly 6db to not squash the dynamics and yet also increase the volume (via makeup gain) without blowing up the divers? You would then limit based on the voltage.

Does that make sense?

Re: Max Voltage during Live Sound???

Actually when you think about it the RMS power going into the T39's should be roughly 25 volts, right? I am getting that figure from the peak limited power of 50 volts - if you limit at 50 volts then the average should be 25 volts because 1/4 of the peak power is half the voltage, no? So maybe those...

Re: Max Voltage during Live Sound???

I'm also curious about this for two reasons: 1) I also have the DL1608 and would love to know how those limiters work 2) I have always felt that using the limiter procedures here - limiting the voltage via a 60 Hz sine wave with my DSP to 50 volts for T39's - really cuts the volume of the cabs to an...

OT12, T39, W6 at outdoor fair

Played a decent sized outdoor church fair a few weekends back and utilized my BFM rig. I used 4 OT12's - these are the older ones - I bought them used here on the forum. They have compression drivers instead of an array and I added the horn diffuser piece to 2 of them. So I lined them up on stage wi...

Re: D-Fend Settings??

In case anyone's curious the unit arrived today and I have programmed it per the Wizard. The choices in HPF for subs are 35Hz, 50Hz, 60 Hz and 85 Hz. The Wizard assigned a 50 Hz hpf. It was very easy to program and the wizard gave me smaller limit parameters than I'd like. I manually programmed the ...

Thanks Gregory. I ordered the unit so I'll give my feedback on it when I set it up.

Re: D-Fend Settings??

Leland made the cabs for me and as a result I don't have the plans. I know they should be limited to 55 volts. And I high pass them at 48 Hz.

Hence my estimates above.

You had the original prototype didn't you Bill? And you created the speaker cabs. What would you use for Fb and F3?

Re: D-Fend Settings??

I'm not building a box - probably just velcro it to the cab so I can remove and not have to put screws in the cab. Or just place it away from the cab. I don't know - no rack or power required, no knobs to turn just set it and forget it. Even a dope like me can't screw it up - which is a major plus. ...

Re: D-Fend Settings??

You can use one D-Fend for two cabs in parallel. Look at the manual.

You can actually use it for up to 4 cabs provided the power and ohms are within the stated limits.

D-Fend Settings??

Thinking of pulling the trigger on one of these for a pair of 24" T39's with 3012LFs. Here's a link to the manual: http://www.parts-express.com/pedocs/manuals/290-683-eminence-speaker-d-fend-sa300-manual.pdf Looking at the manual's definition of F3 (the frequency where the low end response cros...

Re: Grills for WH8 and WH6

Cool - so you replicate the angles on the frame as they are on the cab so it slides in, correct? And I assume you seal the holes you drilled into for leaks?
