👎 Cons

The CL2 rating makes it suitable only for residential use, not for commercial or plenum spaces without further certification.
The 250-foot length may be excessive for smaller, single-room audio setups, potentially leading to material waste.
As 16AWG wire, it may not be ideal for very long runs or high-power applications where thicker gauge wire is recommended.
