After experience my buddy's A5s, I am now in the process of building my own. I will be using 1005B/288-16G and 825 or 828 cabinets. I want to explore the possibility of adding Electrovoice T350 tweeters to the mix and build the Hiraga A5X crossovers. Reading through the great designs, projects and associated comments from a number of you, including those for MLTLs with 416 and 604 series drivers, I am wondering if the 825/828 cabinets can be retrofited into one of GM's MLTL for 515 and 416-8A series drivers for my "A5" project? That would have the dual benefit of adding mass and bracing, as well producing additional lower octave of bass.

Hoping for expert advice from this group before I start this in the spring. Thanks in advance.
