I am making an 85L Vented enclosure to go with my DPL12. This will probably replace the 54L because I can just plug the port if I do not like the vented application and I’ll have a nice 85L sealed box. So what do I do with the 54L? I have no use for a sub anywhere else. Maybe put a Shiva in the 54L and put it in the same room? Would it be hard to get them to sound good together since they are different sizes and the 85L will probably stay ported? Would I have enough power in the 250W plate amp to run both?
