Excellent. Any chance you could list the measured parameters of the V1 & V2 parameters side by side ?

Indeed. And when you measure them under large signal behavior you'll be even more baffled :) |

The moment when you get exited about the fact you got a pair of sparkling new 12 inches you want to test for the first time. Priceless.
Then you measure them. One has a Fs of 77Hz the other one is 115Hz. Ooops.

Surely legal action can be taken if manufacturer specifications wildly differ from actual ? Do large audio firms tolerate this? |

That was P-audio SN12MB. Still have those two somewhere in some boxes. My first and last encounter with P-audio.

Get both drivers in question and measure them yourself, or get someone with the right equipment to do it for you. Even it's just to satisfy your curiousity,

A speaker store in Praque measured the T/S:
good-old PD186: http://www.prodance.cz/files/dl/1/1979/TS_PD186.pdf PD 186 MARK II: http://www.prodance.cz/files/dl/8/15605/PD186_2.pdf Interesting site, they also have measurements of RCF LF18P400 and 'G400. I'm not sure if I'm yet ready to accept that the reincarnation of what I thought to be the greatest mid-BL 18" driver available has a Qts between 0,52 (published) and 0,67 (measured). |

Once you can accept, that "some" manufacturers (and distributors), will lie through their teeth, to get your hard earned into their pocket, you can accept most things in the sound world. At least Celestion, B&C, RCF, Beyma, 18sound, still make decent 18" reflex drivers. Waiting to see how long it takes for this thread to be locked or deleted.
