18SW115 VAS - 189
PD1851 VAS - 182

Woow, a huge diference that is. :-)

What about 12mm vs 15mm xmax and a lot more difference in x-damage? More xmax more displacement isnt it?

I'm talking about PD1850. Wink


Regarding Xmax/Xdamage, with so many manufacturers fudging this figure, I prefer considering
hc-hg/2, and the driver BL, Vas.

This gives an accurate idea of what will be happening with excursion at high power.

Also, high efficiency cannot be countered by fairy tale Xdamage figures. LOL

I got my maths wrong. I want to be putting much more than 550w/driver  into my v18-1000's which is what I would be doing if I ran two off one channel.

I didn't have the time to do any test, but I do have 4 of Francis-build hogs &:
Void v-1000's, pd.1850's, rtm 1500's AND rcf lf18n451 laying around.

The last one has ok specs I think, at it's only 300 euros & Neo, but the xmax is not as big:
Thiele/Small Parameters
  • DC resistance: 5.0Ω
  • Mechanical factor: 6.0
  • Electrical factor: 0.25
  • Total factor: 0.24
  • BL Factor: 30.2 T · m
  • Effective Moving Mass: 235 g
  • Equivalent Cas air load: 245 liters
  • Effettive piston area: 0.122 m²
  • Max. linear excursion (mathematical): 8.8 mm
  • Voice - coil inductance @ 1kHz: 2.6 mH
  • Half-space efficiency: 2.54%
AND did any of you check out:
rcf lf21n51 with a BL of 39
or the lf15n451 with a Bl of 33,5

if you were to run two per channel  off a proline 3000 you would be giving them 750w each. wich with a v18 loaded pair of hogs would sound sweet! we ran two of ours off an old wharfdale mp2800 at 8ohms for a while giving them 600 each and never had any complaints. thats the great thing about v18s, they still sound good at lower power, but when you get the amp to spank them, well youve hered ;).....
 
also when you save up for another amp for your kick section you could get 1100 into them each off the proline if you were to use one per channel so its also pretty future proof.
 
another plus of you guys getting v18s, link ups!

Have been testing new 5"VC UK driver on the block, and to me, sounds like it drops drop deeper/warmer than PD1850/V18-1000/PD 1851, and also stronger than all 3x.

ive always wanted to try the Volt RV4514 looks good on paper, but looks like a bugger to re cone, and is quite pricey!
