Very important question, not mentioned.

What amplifier do you intend to power 4x Void V18-1000s with?
Probably a labgruppen FP14000.
Or any decent amp that is able to feed around 2500w per channel @4ohm. This is what I've read around SP. 

If I'm not unpleasant, Could you please reply to my previous questions? Specially the about HPF. Sorry for asking again.

If I were you, I would not trust all manufacturers amplifier specs as truth.

90% of amplifier manufacturers these days, provide measurements taken  at 1khz.

For Reggae/Dub systems, Sub amplifier selection is critical.

Member here once stated  Crown Macrotech MA5000VZ, performed better on sub, than Lab Gruppen FP14000.

I would suggest:
  • Void Infinite 8MK2 or Powersoft X series.
  • 40hz/18db Butterworth HPF for 4x V18-1000 loaded Superscoops.
  • Add chamber wadding as suggested in Superscooper plans
Above are measures I was suggesting.

Yeah, you're not considering getting a bit fresh with the EQ

You'll blow a couple of drivers your first few times out, or you're doing it wrong

You will need to learn where the limits of your rig are. You can burn out a coil easy as with that sort of music and a tiny bit of distortion and still be within your limiters..
Also 2.5k@4R is a bit light to run two drivers for heavy dub, not enough headroom. I would be wanting to have way more amp headroom, that's how you keep drivers happy. Have enough room to hit transients with authority. 2-2.5k a driver.... That's more like it.

From what I've seen of many dub systems, people think they need huge amount of power per driver, because their sub amp/amps, are not delivering what it says on the tin, down to 40hz.

Void Infinite 8 MK2 will deliver exactly what spec says, and exceed it, given right conditions.

Have seen Void Infinite 8MK2 power 2x 8 ohm Turbomax 1500s per channel, which must be one of the most difficult loads on the planet.

I recommend the Void amp or Powersoft X series, because I have heard them deliver sub notes with quality and authority.

Have heard many lightwegiht amps rated at double power of the Void, and clipped before matching it's performance, on the same load/rig/power.

The best advice I can give, is wait until you have loaded your boxes

Then try a multitude of different amplifiers with your processing and music through your boxes to make a final decision

Yeah, I've read a lot in SP scoop forum about Void Infinite 8MK2 and Crown Macrothech MA5000VZ. I guess it would be great to get one of them. Unfortunately, as you already know, both of them are out of production; just finding a used one seems to be very difficoult. At least I've searched many times in the last period, without luck.

Also, I have to find a compromise between amp quality and costs. I'm not sayng I'll buy crap.
About Powersoft amps: I know, they are are great. But Their cost is too Cry

Luckly, in next months I have the possibility to test 4 scoops with some decent amp my friend owns, I'll let you know.

Thank you for other suggestions

I'll keep maximum attention on EQ. Also, i will try to get a big man amp to have enough headroom. Thank you for your tips.

I honestly hope I'll be able to avoid blowing stuffs. Also, as I was expecting and you confirmed, the kind of music (Dub) play an important rule in this topic.

Ken here in UK  is selling Void Inf8mk2.

Powersoft K20 Will power 6x V18-1000.

You would be surprised how well MA5000VZ, Crest CA18 will power 4x V18s.

Ken? Who is Ken?
Anyway, I totally understand the importance to have a good amp to drive 4 v18-1000. Unfortunately I can't afford the price of wood, drivers, cables, amp etc everything in few days. I will buy things month after month. Meanwhile I can test and play with new scoops thanks to my friends amplifiers.

I will consider void inf8mk2, powersoft, crest and crown. I will give a try to labgruppen too. 

I would ask the "ken" contact (if Ken is a guy lol), but as I told, I'm not going to buy an amplifier today. Anyway It would be nice to know the price, just to have an idea.

If dude has mind made up on Superscoopers, Voids would be one of the top  drivers in it.

However I think more drivers would work well in the Mykey Scoop.

Voids in Mykey Scoop would be real loud, louder than PD1850, but just need "few measures", to ensure warmth.

Sure a few 18sounds drivers, will pound in Mykey Scoop as well.
"few measures"? are you talking about crossover points / eq?
and moreover: Which 18sound driver are you talking about?

Anyway, if so much people is happy with Void and superscooper, I think I could go with them. I just hope they will go low enougth. At what frequencies would you HPF 4xVoid in superscooper to find a good compromise between sub notes and overexcursion?
Thank you for your patience, I know I have lot's of questions

Your HPF should never change, regardless of the amount of boxes you use

I'd set a super scoop to be 38hz 18db BW personally

You will be absolute pleased with a LAB FP14000. 
Dont get blinded by what you read on here. 
LAB FP and PLM amps are just as good and more, compared to Powersoft and Void. 
They just cost alot more, so not many will spend the money on them.

But they are beasts.. No doubt about it. And more rider friendly Big smile
