Hi John, thanks for your help.
If I acquired a set of advent replacement woofers, I saw on another of your posts a DQ10 PDF reference pgs-35-37 showing bracing alterations, which I could do. (I'm a cabinetmaker). So would there be a schematic of the crossover changes necessary for this to work? Also just to be clear, you are saying that the midrange in the image with the silver ring around it Is possibly an LPG but hard to find ( this is stamped Regnar on the side). and I would be better off replacing both midranges with the Peerless units, or keeping the original I have and getting one more?? And if so, is this still the same crossover setup as with the advent replacements?
Thanks again,
