Hi
I'm sure that this has been covered before: The x1 plans say that the cabinet is designed for the sd18. What will happen if a void v18 1000 is put in? |

The Qts and Vas on the drivers is quite different, I wouldn't try it.

We're about to! from the sims we've done it looks like out of the PD1850, SD18 and the V18-1000 the SD18 has the flattest response with the others producing a dip in the middle however that dip is only 1-1.5dB down so it's debatable whether or not you'll actually hear any difference however whilst Rog used to proclaim a more useable excursion than the Xmax would suggest for P.Audio drivers going on manufacturers figures the SD18 has half the excursion of the V18-1000 so i'm guessing what you lose in flatness of response you gain with a better power handling before excursion limits are reached anyways we're half way through building an X1 to test with a V18-1000 so i guess we'll find out |

PD and P.Audio are using different ways of calculating the Xmax. If P.Audio would calculated it the same way the SD-18 would have an Xmax of 9 or 10 mm. The PD has only a gapdepth of 9 mm iirc, which is actually pretty small for the calculation used. Void doesn't show enough data to know which way they're using, but looking at size and weight I would say they use the same calculation as P.Audio. So the useable excursion could be even higher, but again not enough data is released to be sure about this. Rog did say the V18 1000 could be used in the X1 iirc. |

I have 8 X1's with V18-1000's and they really do shake anything to
death and break your back as well. its an awsome driver and i wouldn't
have used anyhting else.

Has anyone heard X1's loaded with SD18s and V18-1000s side by side?

If it aint broke, don't fix it.
(and my own bit) If it is broke, fix it. (and more) If you can't fix it, take it apart and see how it "worked". |

hey Matt, i actually think it was Rog's suggestion to stick the Void in it instead. I wouldn't be getting too worried about straying from what it says on the plan's.

As far as I know Rog suggested that the design had to be changed for use with the Void driver.

Has anyone taken measurements on one? I would like to see the impedance peaks and the frequencoies they are at to see how close they come to the design. |

Alex promised the measurements of the shootout, but I assume he is rather busy atm.
