WOW !!!
a great work but it won't be a primus 362 anymore !
It also means that you think the original drivers quality deserves all those mods. But why not do a complete new enclosure ?
I sure will be interested seeing the measurements before/after.
About measurements : Wmax, you're generally asking for more acoustic stuffing in the boxes (especially in Primus series), have you seen real improvements of the measurements at low frequencies ? Because in the Primus 360/362, the crossover is at 350Hz, so to see any difference under 350Hz, the stuffing has to be quite thick, am I wrong ?
