Ok as promised here`s the plots
(edit ..all plots at 600w a driver) indoors 1/4 space. plots for 1 to 4 boxes 
and this is the plot for 1,2,3,4,6,8,12 outdoors 
Seems to go higher tha I thought! Did notice that it handles the upper bass very nicely. Nice hump at 35hz as well and obviously the more together = more fun! As to price I think they`re going to be quite "cheap" as they use off the shelf drivers and aren`t too complicated to make? Obviously the self powered versions are gonna have the cost of an Xta amp. I`ll let you know when a price is set? .p. Edited by Phil Boutle - 22 December 2006 at 9:58am |

those plots look yummy!
I used the traditional NCA 2*18 V bin over the summer, and that had some thump. how would these compare to the V bin in terms of response and size/weight? blue skies, chris. |

you lot have become shameless 18sound whores, you know that?
i hope this means you'll be able to cut some amazing deals as distributors to pass on to us humble end users then...  around about this time next year (we hope) we ought to be in a position to upgrade all the 15"s and 10"s in the rig for 18sound neos; smps touring class amps first, but that'll be the next big overhaul.

The reason is simple.....they work really well and are really reliable... As for deals you`ll have to butter Steve up at NCA ...I`m only a user like you! .p. |

Is it a conventional or a ND driver (the 12" I mean)? I ask because the NDs are sensitive to heat, so putting their magnets in a small sealed back chamber could be bad. It does not need to be a breakdown at once, but they could loose magnetic flux over time...

It`s a normal ferrite driver, and the drivers are reversed so all the baskets are in the horn mouth. The way they`re placed means that they have large side vents which allow the heat to be passed out of their sides rather than out of the pole piece vent.

That is a good thing. Did you compenaste for the discontinuity in flare rate at the horn throat caused by the magnet?
So if you want go down to 35Hz I guess it is a pretty high XMax driver with relatively heavy cone, right? Does it sound really good at 200Hz? I mean, measured frequency response doesn't tell to much about sound quality.... Edited by JD01 - 26 December 2006 at 2:50pm |
