So, in your opinion, HOW low can this midrange driver be used ?

VMPS used to use this driver down to 166 hz, according to it's ads.
Now, it is 288 hz.

HERE is what I am asking Danny ?

I am no crossover expert, just an audiophile.

But I thought that to use a driver down to 166 hz, like VMPS used to do, it must be happy PLAYING an octave below that ?

That would mean the VMPS NEO MIDRANGE DRIVER would have to play down to 80hz, maybe eveb receive some baffle support, huh ?

Is what I beieve about a crossover correct ?
OR Danny, can VMPS make it's 10 inch midrange driver perfectly fill in for the missing part of the crossover ?

It is "said" the VMPS putty system adjusts the Q of the driver, well maybe so.

But what would putty have to do with the roll off ?

I THOUGHT the 10 inch VMPS midrange Drivers roll off was determined by magnets, cone type, etc, etc.

HTF can Putty make a 10 inch midrange driver roll off differently.
