Hy guys!

We run 4 X1 with the PD1850 driver and it sounds great! But after all it's not enought pressure for our music & our taste. (we play dub & dubstep and run a regular bass night in switzerland called "fraction")

One possibility would be to just build more X1's. Wink
But after all (Wood, Amps, Cables etc etc), it's to expensive for us at the moment.

So i thought chanching the driver instead would be a good alternative. I thought about using the Royal Turbomax B1000 M3 or maybe the Void V1000 or even the Royal Turbomax 1500 I M3 instead of the PD1850.

We would win alot of power without investing alot of money when we would sell our PD's. And this are all very good drivers as far as i know. I heard the Void in the X1 a few times and it sounds great, so i'm especially interessted in some feedback about the Royal Turbomax Drivers.

Some infos aside:
we run 4 es18 with pd186 as kicks above.
the x1's are powered by 2 Crest CPX 2600, Bridged at 4 Ohm (so about 3000 Watt per Apm)

(offtopic: does somebody know if it's possible to run the Crest CPX at 2 ohm bridge?)

Thank you for your feedback & opinion in advance!

From what I have heard, 1850 gives higher SPL than V1000 in X1.

What are your crossover points?

Not sure if running those CPX in 4 ohm bridge is the best way to power them to be honest. Have you tried a bigger / different amplifier?

From the specifications, the CPX shows 1300W at 1kHz, 2 ohm, 1%THD. Suggests actual output is more likely to be below 1kW, power supply is also going to be quite pushed at lowest impedances.. Not giving you much headroom, especially as 1850s happily lap up a clean 2kW Smile

have you considered a single mono stack of wsx with the pd1850 driver? 4 would do more in the 35hz<80hz range than four x1assuming you centre mono stack themi   should think....... 4 loaded with v18-1000 is pretty deadly id imagine the same with pd1850....... stack of six even more potent :P just a thought...... also are the x1and es 18 time alignedetc??? what dsp and settings are you using?
If you want people to feel the bass then a reflex design is probably best as you get the most air movement per decibel from those.      errrrr yes wtf?

It's been said many times that PD.1850 does not fit into WSX

I think your best bet here is a bigger amp for the X1s... the drivers (im told) are pretty much some of the best for those cabs, but, they will take almost 2Kw/driver! so rather then replacing the drivers or building more cabs why dont you borrow a bigger amp thats closer to double what your currently using and see how she goes..........

Rent a bigger amp, see what happens. I don't think your current model is doing them justice.
