The cone might have something sandwiched in it, but apart from that it looks like treated long fiber paper. Appearance wise it looks identical to the material of the v1000 cone, but looks can be deceiving There's an extra layer of something in the center, maybe kevlar reinforced paper (hoping.) Fairly unspectacular overall. My cone test is to stick my finger into it from behind & see how much it flexes , this passed the finger test .
Of the affordable, and readily available choice i had, mostly brasilian manufacturers: selenium, snake, profissom, oversound & some others it seemed the best bet. Very few 18's made out here seem good for horn loading. If you ever visit Sao Paulo you *must* go to santa ifigenia, there are literally fifty pro-sound stores in about 4 blocks all competing, v easy to get a quote & just tell the guy in the store next door i want more discount! cheers, Rob |

I have had a look at them before (when you first started posting your
project) and looked at their big 2" driver, but couldn't get any info
so I stopped enquiring. The SUB800 does look promising, but I doubt
they'd spec anything a la Kippel/Dumax.
Is the cone re-inforced in any way? |

Has anyone seen oversound speakers outside Brasil? Their 18" is pretty effective & so far no problems, 800Wrms EBP=130, BL=31, deep conical cone. It's v similar to PD1850 (only got a baby 4" VC though )
I buy these in Brasil for around 80quid each (420r$ after haggling ) cheers Rob |

Hmm, P.Audio doesn't give too much info on that driver, so it might be
a runner (I went with the Challenger 18-650EL which I will give a go in
a horn cab sometime these holidays). Cone looks like it might be a good
choice, though it's hard to judge with so little info on the site and
not having ever had one in my hands (the local P.Audio dealer doesn't
keep them) What other hints has Rog dropped to people over time
regarding hot product choices?

right then,
the driver you want is the P-Audio R18 100B £135 each from pro audio parts, you can stick about 700/800 watts into each one! (havn't tried them myself, but thats what Rog advised when i was looking for a cheaper driver for the 1850 cab.) Ben |

@ tbmike: wrong 18 and enough power means you'll play catch with the
cone after a while or your driver will have developed a second
suspention free of charge . Rog suggests the 186 Cab for lesser drivers (1850 has >2:1 compression ration IIRC.

well,if the driver is similar specs to an 1850 you cant go far wrong!
1850 specs being Fs 30hz Qts 0.21 Vas 250litre Xmax 11mm If the specs are wrong and u put any 18" in it,it might make mainly upper bass and no lows at all....but it will make some noise -I thought the Pds are quite cheap compared to some 18" prices! |
