I know having 6 speakers and not a multiple of 2 is a crap...but here we are...

I have to powering x6 superscooper 18tbx100 rms 1200W. IT can handle 2400w in continuos.
All speaker are 8ohm, many possible connection with lots of series/parallel conttector that i can use!
I've varius options but id like to feed them with the best possible combo, my aviable amps are:
9001 crest
x2 powersoft k10
ab class amp 3200w @8ohm bridge mode.

having different ohm loading on the same speakers could be a problem? for example if im wiring them from different amps channlel... es 4 of them 4ohm loading and 2 of them 8ohm.

Do your venues have decent mains supply or UK 13a plugs?
Forget Crest 9001, if not decent supply in your venues.

Would not suggest K10, have seen this amp, eat 4x drivers, when it clips.

B&C cannot handle 2400w continuous, don't believe the hype.

Powersoft K20, Void Infinite 8 MK2, MC2 E90, would power 6x of those quite easily.

Don't buy cheap Chinese lightweights, will cost you more in the long run.

QSC PL380, would also easily power 6x of these, I have 1x for sale. £1K

those amps are good but mine are from the list above and are the actual only possibility.
so ive to arrange something with them.
yes the venue have a 64A plug, so i guess nuff current.
my 9001 is feeded by a 32A monophase plug
i belive in b&c parameters actually LOLLOLLOL ive pushed them for now almost 15 years with no complaint at all...arent f1 but is a good compromise. with a good kick and processing sounds proper to me.
thanks

In a building with that supply, I would prefer the QSC PL380 to the 9001, for those 6x drivers.

The PL380 is completely different beast, on decent mains, so is the K20.

3 8ohm drivers per channel (2.6R) is ideal for many modern high power amplifiers. PL380 is a good, reasonably priced option however if you already have a K10 that too will power all 6 properly 3 per channel in parallel

I've never liked the sound of the K10.

To me K20, sounds much better, not just the power, but more natural sounding bass notes.

Sound quality is subjective, one man’s meat is another man’s poison.
The K10 will properly power those drivers. As to what sound quality is appropriate, well i know what i like but i am in no position to tell someone else what they should like.

thanks

The B&C 18 TBX 100 are approaching 20 years in production. Fourteen years ago, one 8-ohm B&C TBX 100 would burn-up it's voice coil on a single channel of a Powersoft K10. So, three B&C TBX 100 in parallel mode would be an ideal fit on a Powesoft K10. It won't be louder than the Crest 9001 however, if weight is the reasoning for moving towards a lighter weighing amplifier, the Powersoft K10 will be fine. 

Best Regards,

thanks for the adivse and comment!

what id like to understand is if for example having 4 scoop on a k10 and others 2 with another amp, from the list above(x2 k10, 9001 or ab not chinese amp)... id like to have a good powering, in venue nuff current aviable and the rack have more W to spent.... thanks to all

Another couple of options to consider:-

Put 2 drivers per channel on 3 channels of the 2 K10s and keep a channel spare. 

Run 2 drivers per side on one K10 and 1 driver per side on the other. With careful limiting and gain control no reason this cannot work.

Have done both these options many a time in the past.

If your limiters are based on peak & RMS voltage, and the amp can deliver both without clipping, then there shouldn’t be any adjustment needed when you vary the number of cabinets per channel.

This is how your external DSP limiters should be operating.

With the Powersoft K series DSP, the only limiter types that need adjustment depending on nominal load are the TruePower and “Current vs. 8 Ohm” options. While those are brilliant for making a well-designed loudspeaker as bombproof as possible, I wouldn’t recommend that most people use them without proper measurement and testing in a controlled environment.

If I was playing in venues, always with 32A/63A 3PH supply, or on 64+ KVA generators, my sub amp of choice would probably be PL380.

But they are a bit hopeless on 13A plug, Domestic ring main, so I sold 3x of my 5x. Cry

There is nothing to gain using your example. You are only using 6 boxes. If you were  12 - 18 boxes, I would see the benefit of the idea you are suggesting.
