Frequently asked questions
Which handles speech intelligibility better?
The Control 321CT is specifically engineered for speech intelligibility with its larger driver, higher SPL (118 dB), and controlled dispersion pattern. The Control 424LP handles articulate vocals adequately for moderate spaces but is less optimized for speech-heavy applications.
What's the key installation difference?
The Control 321CT requires a standard 14.4" ceiling cavity and is a single unit, while the Control 424LP's ultra-low-profile backcan (under 100 mm deep) fits retrofit or shallow ceiling spaces where the 321CT cannot mount.
Which is better value for a multi-room system?
The Control 424LP is sold as a pair at budget pricing, making it economical for outfitting multiple smaller zones. The Control 321CT's higher power and output justify its mid-tier cost for larger single spaces or speech-critical applications.
Can both handle paging and background music equally?
Both support paging and background music, but the Control 321CT excels at paging with superior speech clarity and SPL, while the Control 424LP balances both functions well in moderate-sized rooms at lower cost.
