an untreated apaper cone would not survive too long even if it the speaker was not sprayed or dunked. sunlight would eat the paper, slowly.

treated paper/wood/hemp etc.. is resilient but will not survive a dunking like say ceramic, polyproplene, kevlar, carbon etc...

the scanspeak speakers I lost had kevlar cone but the water got into the coils and withing a week the 3 of 4 coils were corroded beyond repair/use.

Scanspeak wouldn't have dreamt of their voice coils getting dunked in salty water! Otherwise they would have used copper wires with a different insulation for the VCs, one that is commonly used in marine-grade electricals.

Thanks old men for sharing some great (and hard learned) information! (as if I am so young) I don't think it would be practical to safeguard against dunking as such, but I wanted to confirm that environment resistance should not be given too much of importance. Though paper/wood would be relatively inferior to synthetic materials, it should be safe to trust reputed manufacturers at least for products specifically intended for car usage.

BTW, I understand that both the speakers I mentioned use Vifa co-designed woofers (obviously through unofficial sources). Alpine also uses a ring-radiator tweeter (supposedly excellent?). I am more inclined towards alpines because they also have highly tunable cross-over and the model I mentioned is available at bargains because of being discontinued (models that replaced it bear MRP tags in thousands of USD!)

Sorry, I am slowly getting OT, as usual!. Though, I hope JTRider should not mind it because I think by now he should be done with his show-off

I think the water was MORE than salty.

Navinji, no comments on this question?
Alpine's current line of type-R also uses it, don't know about the past though. I thought you (et al) might have something to say, since type-R has been one of the often recommended speakers on this forum.

what do you want me to say.

it is common knowledge that Alpine had Scanspeak help them for their F1 series of components. that the type R series also carries the tag could be a mix of marketing and trickle down.

I have not heard alpine's rendition of the ring radiator. I have however heard Vifa's version and Scanspeak's version (before they along with peerless were "merged" by Tympany). I thought SS's version had a better rendition, I believe both versions can be bettered. Also the veriosns I heard did had complex but yet not finalised crossovers on them, I hence beleive that ring radiators require some serious crossover design.

Since I am really a KISS guy, persoanlly (as a DIYer) I would rather use a driver that does not require this level effort and these number of components. The money spent of the XO could be used to get a nicer behaved tweeter. Dont get me wrong, the ring radiators are terribly detailed. But detail isn't everything. I want the music to give me goosbumps. to make me dance or alteast to get my aged toes tapping.

It is great becasue it allows you to tinker and learn. But santosh do get LspCad or Clio or Calsod or something similar at it will allow you to graphically simualte what each tuning does.

Hehe...what a question! Why would I ask if I knew the answer? I just wanted to get more enlightened, like what you just did. You know very well, what may be boring stuff for Gurus is most likely to be exciting to newbies (like me) Your patience is appreciated.

clip, download a software called WinISD. It is free. It will not do as much as Calsod or Clio but you can try it. Speaker Workshop is another simulation software which is free.
