PDs vs Void 18"

Im not sure doing a test on a bench will prove anything?

True, i guess i might just take it round to see what tests he has in mind.

I dont think the issue is the flimsy cone, there are plenty of drivers like Fane XB that go in front loaded horns and last years without any problems.

I think the main issue is the fact that you need a mighty big box to get the best out of these, and dont forget Rog designed this driver primarily for the Stone Love Scoop as I recall, so a rear loaded horn is going to be the optimal enclosure, the best parameters of which would have to be experimented with but I expect something with a larger chamber will work best.

I reckon if there were more boxes suitable to the V1200 then it would have sold like hotcakes.   Just spoke to a friend of mine who does recones n stuff n hes got a PD on the bench at the moment n i think i might just take the V1200 down there and do some tests coz into that kinda stuff. What do you guys reckon?

The PD is more of a general purpose driver than a V18-1200. It's parameters tell you it is often strong enough to handle cabs it wasn't designed for.

The V18-1200 was deisgned to be a scoop/reflex driver. It needs a big reflex cab, or scoop with right Chamber/throat to really perform.

Tighter drivers will tolerate large chamber scoops if they have enough BL and Xmax, looser drivers "mostly" do not like small throat scoops/small volume reflex cabs.

It is actually not that difficult, to design scoops/reflex cabs that V18-1200 would perform well in.

Sensitivity ?

What I can't get is at Levy's v18-1200 shoot-out / testing it devastated the place in a Mini-Scoop, so how comes the PD1850 is still up there & both the Turbomax's creeping up for the crown!
