I'm with Mac on this one...I've owned Bose L1 since 2005 (at that time there was only one option).

For nursing home/assisted living situations, the L1 compact is more than sufficient. The bass module is built into the unit and would suffice for your application. The other models have an option bass module which are a more powerful bass modules than the built in module in in the compact. But again, the L1 Compact would suffice for your application.
