Hi Donfibre.
The MA-1's offered at a good price locally seems like a no brainer to me, go for it before their gone.
RE: Bracing the cabinets:
The original Tannoy cabinetry made for the 15inch DC's were rather flimsy and will benefit from the some extra cross bracing and dampening inside the cabinet.
Adding some extra support will tighten up the bottom couple of octaves.
Hope this helps.
