Frequently asked questions
What is the main difference between these two models?
The LCT 81C/TM fits metric 600mm×600mm ceiling grids; the LCT 81C/T fits US 2'×2' ceiling grids. Both have identical 8-inch drivers, 96 dB sensitivity, 10-watt transformers, and 100V/70V compatibility. The choice depends entirely on your ceiling grid size.
Do both speakers deliver the same audio quality?
Yes. Both feature the same 200mm dual-cone driver, 25mm voice coil, Kapton coil former, high-temperature wire, and 96 dB sensitivity. Audio performance and coverage patterns are equivalent.
What does B-stock mean for the LCT 81C/T?
B-stock typically indicates open-box, refurbished, or cosmetic-defect units that are fully functional. The speaker meets all performance specifications and carries the same warranty terms as new stock, with a lower price to reflect its condition.
Can I use the US model in a metric ceiling or vice versa?
No. The LCT 81C/TM is designed for 600mm grids and the LCT 81C/T for 2-foot grids. Attempting to install either into an incompatible grid will result in poor fit and potential safety or aesthetic issues.
