Ciare 18SW ; Bass Maker or Heart Breaker?

I use the Ciare 18SWs in some bass horn boxes of my own design. Very very impressive, great for sub horns no good for kicks though, they shift tonnes of air and welly up your belly, definate trouser rattlers.

Lean business of Ipswich do them, at a good price too. I have them running on a Cerwin Vega CV5000 at 2ohm stereo and they sound great with roots/reggae/dub.

@ Dub spec any pics of ya horns sound interesting

Their calculations for voice coil overhang do seem rather funny although I think total balls is stretching it somewhat:
(33-10)/2 = 11.5, not 14
11.5mm of real voicecoil overhang is a lot though. 14mm looks like a figure maybe obtained by them looking for the 90% BL point (I think thats what some people use, please correct me if I'm wrong) as using the above formula + (overhang X 0.21) would be a very strange thing to use.

Looks like in the right cab it'd be a total beast. Its very different in terms of parameters to most others I've seen.

The error on the resonant frequency of +-7Hz seems a bit strange too, although its nice to see errors - the PD website needs to state these really if it wants to justify putting their parameters to 5 significant figures (now that really does seem like a gimick).

Reference efficiency is less important in a horn than it is if the driver is to be used in a reflex box, especially a big long horn, the main reason for the low direct radiating efficiency is the high MMS, thick cone and long coil.  With the added mass of the air in the horn the difference between a 200g moving mass and a 370g moving mass will be much less of a factor than with a direct radiator. 

Plenty of British Drivers would smash this.<--Yes Lev very true. Would like PD1850 but i'm in the USA and  don't have the budget for that. Option are down to RCF-L18P300 and TBX100. Lev any thoughts between the too?

For reflex, RCFL18P300 also much superior to the Ciare.
