Modded Eminence Scoop Driver Question

Greetings FSP user. First, thanks for all the helpful stuff you guys have already posted on here! I really hope this hasn't been covered yet and sorry if it has. My question is in regards as to which driver would be best suited for this cab(modded Eminence scoop) , As i know the PD1850 works wonders, but living in the US i don't have access to them here. From what i've read on here about what to look for in specs for drivers in scoops i have it down to two drivers im looking at. But i wanted too see what you all though as which one would be best, or if anyone has heard these drivers in scoop. Thanks!!

Thanks for the reply.Yes i believe so, the local guitar shop stocks them so i'm sure i could order the pro audio ones threw them.

might be worth looking at the Celestion CF18VJD.......

Celestion CF18VJD 18" 1600 watt Ferrite Subwoofer 8ohm

The new Celestion CF18VJD is a versatile ferrite magnet subwoofer suitable for reflex, scoop or horn loaded use.

Celestion have not released the availabilty date and price, however to avoid disapointment please contact us to register your interest.

• 18” ferrite magnet, cast aluminium chassis LF driver delivering 1600Wrms (AES Standard) power handling and 97dB sensitivity
• 5” high temperature, dual layer, Inside/Outside voice coil for higher efficiency, preventing sensitivity loss through thermal compression
• FEA optimized magnet assembly delivers highly symmetrical cone –movement, leading to exceptionally low harmonic distortion
• Vented front plate increases airflow to provide enhanced cooling
• Twin demodulation rings reduce flux modulation, minimizing electromagnetic distortion
• Double suspension and “multi-roll” surround provide exceptional linearity at extremes of cone excursion

So any thoughts on the drivers i was asking about?

whilst you can speculate how a driver may sound in a box, with scoops, you will literally not know, until you try. I'd even say this is more important with small chamber scoops like eminence, than large chamber scoops.

out of those 2 drivers, i'd go for the B&C, with 10mm true xmax, and half decent BL, and mid qes/qts - should get a bit more out of it.

only thing is eminence scoops have a shallow chamber, so i think your driver will be too deep.

really would look into other drivers: find out if void v18-1000 can be shipped to you in the us...im sure they have a distributor out there
