Yes, I agree.

40 drivers? Huge audience?

That sounds exactly like this:
THE MATTERHORN | Danley Sound Labs, Inc.

Depending on lots of things, one huge box may be less work to build / shift / set up than 40 individual boxes.

Yes you can also build 10 M-power Servo's (if you can get oem suply), You also need the Servo amplifier. for 10 of those you can build 60 cubos.... But then you need warehouse space

Two options:
- The B&C 21SW152 in a ported box tuned wherever you want it. That's your small box.
- B&C 21SW152 in a big tapped horn. That's your big box.

Both will go below 30Hz with authority. The tapped horn will go roughly 6dB louder, but will be roughly 2x the size of the ported box.
You might need more power.

I'd probably go for the Orthorn for the tapped horn, and a ported box is easy enough to design, so I'll leave that as an exercise for the reader.

I like the Othorn very much, but I have not heard every sub out there.

Mine have the B&C Speakers 21SW152-4, so they are 4 ohms not 8 ohms. You may load load them with a variety of different drivers, so you need to match power and ohms with the driver you choose.

Thanks a lot for your fast response.

Aplication: Mainly for EDM for huge audience, outdoors.
2nd. will be live sound
Budget: top of the line Drivers, USA market ( No IPAL or 2 Ohms subs )
Cabinet size and weight are not a problem. but single driver box preferably.
Amp power: 2400 watts 8 Ohms bridge mode. or 1200 watts 4 Ohms

Goals:
Very low response (30 Hz or down)
2 or more options will be appreciated, (large an small box size)

thanks everyone,

As I said it depends on the driver you choose, and the Camco V6 will do the job, but it is way bigger than the spec you gave (2400 8ohm bridged and 1200 4ohm stereo).
I've never used Camco amps for subs though, so I cannot speak to that application. I have used Camco V6s for top boxes in a mixed aystem, but the d&b B2 subs in that system were powered by d&b amps(of course).
