Explore the system →Why Southwestern
No touchscreens. No software fees. No nonsense.
When you call us, the person who picks up is the same engineer who designed your system. That's the difference between hardware that runs for 20 years and hardware that needs a service contract.
Engineered in-house
Over 50 years of combined electronic design experience. Every PCB starts on our bench in Gilbert.
Repairable forever
Flat-fee post-warranty repairs — $125 for music systems, $150 for DPS. We don't planned-obsolete you.
UL Class II safe
Every product is UL-approved Class II. Safe to install in schools, clinics, and medical facilities.
Real USA support
Phone and email support from our team in Arizona. The engineer who answers built your system.
Who We Serve
Built for the realities of your space.
Industry-specific systems designed around how the room actually gets used — by therapists, hygienists, salon staff, and the customers in the room with them.

Day Spas & Med Spas
Calm, consistent background music is part of the treatment. Our systems deliver it room-to-room without a tablet anyone has to babysit.
