Some internet companies are a little sensitive to have the delivery address be different than the bill to address of the credit card. Internet fraud and all of that. I expect a phone call to Axiom might solve that.
Do you have an opportunity to leave a side door open to the garage? If so, a note in an envelope hung on the front door with "FOR UPS" in big letters might work. Ask them to put the speakers in the garage and lock the door when they leave. I've done that several times.
Ask Axiom for special shipping arrangements. Have UPS call when they speakers arrive. Make a pickup at lunch and a second pickup after work.
If all else fails, have a friend meet you at UPS with a second car, make two trips in the same day or make single trips over 2 days.
