Frequently asked questions
Which speaker works better for a boardroom or office without a suspended ceiling?
The SLP14/T-BK is purpose-built for on-wall installation and requires no ceiling access. The C24CT-BK requires either a drop ceiling or custom mounting hardware, making it less practical for finished drywall or plaster surfaces.
Do both speakers support 70V/100V distributed-line systems?
Yes. The C24CT-BK includes a 30W multitap transformer with switchable taps for 70V and 100V operation. The SLP14/T-BK has a 25-watt multi-tap transformer also switchable for 70V/100V, plus a direct 8-ohm input option for non-distributed wiring.
Which produces louder output for large retail or hospitality spaces?
The SLP14/T-BK delivers 108 dB peak and 102 dB continuous output at 1 meter with 86 dB sensitivity, making it better suited for higher-output requirements. The C24CT-BK's coaxial design prioritizes even distributed coverage over peak SPL in larger multi-speaker arrays.
Can either speaker be used outdoors or in wet environments?
Only the SLP14/T-BK, which carries an IP44 water splash rating suitable for humid retail or exterior-adjacent installations. The C24CT-BK is designed for interior climate-controlled spaces and lacks weatherproofing.
