Let me repeat myself. 
Headroom.... Its All about headroom. 

1000watt woofer with a 1000 watt Amp isnt a good combo. 
The Amp Will struggle to deliver. 
Always double or tripple the Amp power.
Anybody stating otherwise shouldnt deal with audio gear.

Underpowered, Vs equal Vs overpowered amps is a no-brainer.

Headroom is a absolute must!
I am running LAB 12K44 on comps. Insane overkill, but i still havent seen a law that say "you shall always run flat-out" Wink

Its all about limiters. Simple as that.

You need 1000watts? Get 2000 Big smile

Right, i actually run my speakers with oversized amps several times. There are some details that can vary the amount of power a speaker can absorb though: How are limiters set? How long are they playing? Is the heat inside the chamber dissipated in some way? I'm pretty sure the musical program can make a difference too... to make it short, a 36 hours party with fast and bass-heavy tekno music, mostly played by non-professional artists, with a diy rig sometimes controlled by non-professional crews, could be really different in terms of performance and results than the average concert a pa tech is used to. I would not suggest a stranger to overpower his own gear without knowing any detail or his skills level.

Are you serious??? Wasting energy just because the Amp might be way bigger than needed?

Its All about headroom dude.. and control..
If one cant run a rig with double or tripple the needed power, without burning coils to a crisp, one simply shouldnt Touch pro audio gear Sleepy

such a nice rig here! Yess mate, it definitely is less easy than one thinks, but it pays with satisfaction! I'm really looking forward to hear the 4 sbh i built, when the guy who owns them will feel ok to throw a party..

About the last question on the thread, i'm afraid i tested the N401s in theese cabs for too short time and too low volume to feel like having an opinion. However, i think a K6 amp would barely drive the mentioned rcf speakers over their rms power.. while a K20 would be blowing the cones out, if not kept under control..

Lev, with a K20 you could damage those V18s, in such a FLH, without proper limiting, quickly.. 
RMS power handling is pretty small in that small backchamber ;) 
Peak, excursion limited, handling too, depending on stack size etc.

its not as trivial as simply going for the `best/biggest`guns imo

We will make 6-8 SBH. I have 2 questions about this:
I have the choice between Void V18-1000 and RCF LF18N401. Which one would you choose? Genre: DnB € Tekno

Which power amplifier would you use?
I thought of 2 x Powersoft K3 with 2x2600W @ 4Ohm (highest level of K3)


People must stop believing the quoted power of lightweight amplifiers is truth, they are burst figures, often quoted at 1khz,  which gives no idea of true power at sub frequencies.

Would suggest K20.

Will drive 6-8x V18-1000/PD1850 adequately, if you are not seriously boosting 40hz, and have decent mains supply/power cable/speaker cable.

Know this, because I've seen it done repeatedly, as opposed to just reading quoted specs.

Are there no hornresp input sheets available to sim both options?
(or measurements?)
Based on those drivers specs i`d guess the V18-1000 would be a better choice.
K3s should be fine, flhs dont need that much headroom anyways imo as the small chamber/heat will be an issue with too much, not properly managed power available..
