Which wireless security setting?

I am do not assume that anything is unbreakable, as people are figuring things out daily. At one client's office, they use WPA2 with a long passphrase (50+ random characters), MAC filtering on, SSID broadcast off, DHCP off (IPs are manually input), wireless radio only on M-F 7 a.m. - 7 p.m. and output power turned down to only cover about 40 feet. Only him and his business partner use that network and only 4 devices are allowed on (2 laptops, 2 iphones).

I would be very, very surprised if they were to get compromised.
