Hey Folks, Since I won't be embarking on my own DIY mains for a while I want to do some modifications to what I allready have. I am running AR9 mains, the driver compliment is a 1" Sealed Back Titanium Dome, 2 Open frame 5.25" Mag Alloy Mids and 1 10" Bass Reflex sub per enclosure. The cabinent is heavily braced internaly from the factory so adding braces isn't needed. The Mid's have thier own "sub enclosures" within the main enclosure. I was thinking about lining the outside and inside of these mid range enclosures with some sound deadener and then stuffing the enclosures with polly fill (try like 50% for starters and see if it makes a difference) and also stuffing the sub's cavity with polly fill. What about removing the crossover's and noting the values of all the components and replacing them with the same exact values only using something like AudioCap Theta film or Solen metalized polly caps ? And removing all of the internal wiring and replacing it with 99.999% OFC 12AWG. Just things to make a well built mass production speaker even better, and it's allready pretty good.. Yes/No? It's not like any of this is non reversible and it should be beneficial even if in a subtle way.
