    Posted: 25 April 2006 at 6:03am

hey how about using a P. Audio driver in PD1850 horn... P.Audio modelled C18-650el... it was said in the plan that PD1850 and other drivers with EBP over 125 and BL's over 28 can use this horn cabinet.

P.Audio C18-650el has BL' that is over 28 specifically it has 30.78 T-M... so I presume it will work.... what can you say about that?

please help...

the ts arnt horrendusly different actualy, i originaly thought it wouldnt, [and im still not convinced it will] but looking at it, its never going to be as good as the 1850. but its got a better chance than i originaly thought!

what's the importance of this XMAX? are they that important in the criteria of PD1850 horn... will this P.Audio driver be useless if I put it in 1850 horn? or it will work but not that heavy as PD1850 does? even I have low Xmax and all other PArameters are almost the same does this sound poor?

was this driver (P. Audio) are intended for horn application or bandpass or bass reflex, etc....?

Hi, did the P Audio driver fit into the 1850 cab? I own 4 drivers and i'm loving the 1850 cab so i want  to build some, but don't want to waste the cash on ply if it doesn't fit.
Can you feel the BASS!

Xmax (mm) means how far the cone can move backwards and forwards while still being controlled by the magnet, If its exceeded then your driver will distort. If Xdam is exceeded then the driver will destroy itself!
 
Generalisation> So a small Xmax means than that at low frequencys and high power the driver is more likley to get damaged than a driver with a large xmax, (there is other stuff to take into account though)
 
[[[haha just realised i was replying to a 2 year old bit of the thread!]]]
 
To answer you Pozest, im not really sure, i would have thought that the 186horn would be more appropriate. hopefully someone else can help u theough!!!

Thanks Jake_Fielder, you rekon the 186 is a better option or should I settle for scoops? for my C18-el650s. At the moment the drivers are in MTL2 cabs but sound crappy.
