Where can i buy this cone strengthener?

I see someone is asking about the RCF L18P300 compatibility. Well I want to rebuild my 6th order cabs and would be interested in the X1.
My drivers are all RCF  L18P200N. If you can do this you'll have a friend for life.

It's just mod podge.  You can paint it on to the cone.  It will add more weight to cone and make it stiffer.

Rog,
I like this design.  You did a good job.  I've been thinking of using 18LW1400's in it.  I plotted it in WinISD, but my plots are spikier than yours, with peaks at 45 hz and 90 hz but the two drivers' plots lay about the same, so I suspect this is a good driver for the application.  The 45 Hz spike is about a dB higher with the 18 sound driver.  I could not get the clips of the plots to show on this posting.  Can you comment on the viability of the 18LW1400?


By the way, I have no fantastic preference for this driver, but I notice there is little or no mention of it on this website.  Is there some general deficiency with it?  I though EAW got pretty good results with it.

 

Regards,

Rotorbar

P-audio P-18N

is looks like there are some really cheap driver that can perform in this enclosure

remember, DO NOT OVERDRIVE these speakers, especially the cheaper ones because the X1 is a very brutal bandpass with uneven loading of the cone and severe unloading outside the operating range.

if you need other cones simulated in this designs , just ask

hope this helps

 
Any chance of a sim for a Beyma 18 G550 in an X1 cab?
 
 
I think I'm in love with your mum.
