Palacio de los Deportes yes, it has terrible acoustics......... Arena Ciudad de México.... I don't know if you've been there, but it does not have bad accoustics at all..... yes, it is in a weird location, but it is state of the art......... newsflash, both Palacio de los Deportes and Arena Ciudad de México with their 20,000 capacity, sit more people than most arenas in the USA...... even madison Square Garden only sits 15,000.
Arena VFG in Guadalajara and Arena Monterrey ...... even if some of them are old... they can all accommodate any arena show.
