I'm getting a good deal on a 410xlt cab, then later on I will be buying the 210xlt. Will my wt500 will be able to power both cab when I have to setup in a big building.
You can power them both but not in bridge mode, you will have to run the amp in dual mono when running both cabs. This will only give you about 175 watts into each cab, you may find running the 410xlt in bridge mode to be plenty on it's own (provided the 410 is a 8ohm cab) this way you will get 500 watts into that cab. Another thing to consider is that the amp that you have can be upgraded if you wanted a bit more power.
Thank guy once I get both cab, I'll be working on getting the wt800 for the power I need. Then when I go to a Church Program to setup my Eden gear beside another bass system which is peavey that what everybody use in Mississippi, all bass player will be coming to me asking me " Can I play through your amp". It feel good when you have a system that sound so good and make everybody want to play through.
