Frequently asked questions
Which is better for background music in an office or retail space?
The Control 24C. Its coaxial design and balanced midrange deliver natural music reproduction in enclosed indoor spaces. The CSS-H30 horn is engineered for speech clarity and extreme SPL, making it harsh and unsuitable for ambient music.
Which can handle outdoor use?
The CSS-H30. It carries an IP-65 rating, stainless steel construction, and salt spray corrosion testing. The Control 24C is designed for ceiling-mounted indoor installation and lacks weatherproofing.
What is the key technical difference in their design?
The Control 24C is a coaxial 2-way speaker with a 4-inch woofer and 0.75-inch tweeter for balanced frequency response. The CSS-H30 is a compression-driver horn with a narrow, speech-optimized frequency range (380 Hz–6 kHz) and a 350 Hz high-pass filter to cut rumble and feedback.
Can the CSS-H30 work in a distributed 70V paging system?
Yes. The CSS-H30 includes a multi-tap UL-registered transformer with five 70V impedance settings (167Ω to 2666Ω). The Control 24C is passive and uses direct 16-ohm impedance, requiring a separate amp or paging system.
