Question:

Mixing and Matching
 
Can I use two of Control 42 in-ceiling satellite speakers along with two Control 52 on-wall satellites, all with the Control 50S/T subwoofer?  Could I use a Control 40CS/T as the subwoofer?

Answer:

Yes, Control 40CS/T, 50S/T, 42C and 52 speakers can be intermixed in any combination providing you end up with a system having one subwoofer and either two or four satellite speakers.  This is very convenient for meeting the architectural and/or visual requirements of a wide variety of venues.​​
