celestion cf18vjd

Looks like celestion are gonna be rolling with the big boys now with the new 1600w monster driver , spotted it on the site!

5inch VC
30 bl
1600w rms
Qts 0.3

Look good on paper but can't find many people selling them!

AFAIK not available yet same as the 21"

Tony

They are available if you know who to speak to :shh: :shh:

i think lev was planning on taking out some small countries with this one, but i didn't tell you that :silent:

Like the 5"VC, EBP, BL=30, truthful Xmax (which by other standards, would be rated approx 11mm).

Question mark regarding 1600W power handling, and Vas=164. smiley11

hmm on second thoughts, maybe it was this one that was "under inspection" IIRC - would love to hear in super 21" without dogleg

shame they don't state Xmech

On a well designed driver Xmech should have no relevance. It should not be possible to drive the cone to a point where mechanical damage can ensue i.e. motive power should run out before mechanical limits are reached.

This seems to be something that British drivers have ignored in the past.

reason i say is. RMJ turbomax drivers caused quite a stir when they were released years back, because they could move "twice as far" as a PD1850 before damage. (this was academic, as it took way more power to do so.)

it's hard when most manufacturers specify xmax @ 10% distortion or whatever other witchery they use to come up with the number.

it's refreshing to have celestion and BMS stating true xmax figures, because anything over that figure is just a nice little bonus.

Saul, It is probably a point at which the BL drops to a certain percentage below Maxm i.e. 80% BL

Graphs which show BL against displacement are a good indicator but not all manufacturers give this data.

I'm thinking of trying some of these drivers in my mini scoops soon.. ant thoughts from the more gifted out there!!
