Voltive 16/2 Speaker Wire V-1217-4

Voltive offers 16 AWG, 2-conductor speaker wire with a white jacket and a 250-foot box. The conductors use 26 strands of Oxygen-Free Copper (OFC) to minimize signal loss and maximize durability. This CL3P-rated plenum cable is UL Listed for safe installation in walls, risers, and plenums, ideal for in-wall or above-ceiling speaker runs and low-voltage systems requiring fire-safety compliance. The combination of OFC and plenum-rated jacket positions it well for both residential and light commercial projects where clean audio performance and code-adherence matter.
SYSTON 16/2 Fire Security Cable, 250 ft

This 16 AWG, 2-conductor control cable from SYSTON is designed for fire alarm, security, and low-voltage systems. It uses 100% stranded bare copper conductors for reliable conductivity and features shielding to guard against EMI. The CMP/CL3P plenum rating enables safe installation in air-handling spaces, while UL/ETL listings provide independent verification of safety and performance. Its shielding is particularly useful in environments with potential interference, helping ensure clear signal transmission for critical alert and communications systems.
Voltive 16/2 Speaker Wire, V-1217-6

This longer Voltive option mirrors the V-1217-4 construction with 16 AWG, 2-conductor design and 500 feet of white jacketed cable. OFC conductors reduce resistance and degradation over distance, while CL3P plenum rating and UL Listing ensure safety for indoor installations, especially in networks that span larger spaces or multiple rooms. The higher length makes it suitable for larger dwellings or small commercial rooms where speaker wiring or low-voltage circuits need extended runs without compromising signal quality.
EWCS 16/2 Shielded Plenum Cable, 500 ft

EWCS provides a shielded 16/2, 500-foot plenum-rated cable with 2 conductors. This model uses bare copper strands, a 300V rating, and a 100% aluminum Mylar shield. It employs a low-smoke white PVC jacket designed for in-wall, in-ceiling, or HVAC environments where EMI protection and flame safety are priorities. The shield reduces interference for audio, alarm, and data signals, while the plenum jacket helps meet building-code requirements in commercial and residential installations.
Custom Cable Connection 16/2 Plenum Cable, 500 ft

Custom Cable Connection offers a 500-foot 16/2 cable with a plenum-rated CL3P jacket and shielded construction. It uses two 16 AWG copper conductors and emphasizes UL-listed safety, plain language compliance, and robust shielding. This option is suitable for general low-voltage installations including speaker runs, intercom lines, and alarm circuitry where long runs, safety ratings, and signal integrity are important.
Elite 16/2 Plenum Speaker Wire, 1000 ft

Elite Cable’s 16/2 Plenum Speaker Wire features 100% Oxygen-Free Copper conductors, 16 AWG, and a CMP/CL3P rated jacket. With a generous 1000-foot length and UL listing, this option is designed for professional-grade installations that require minimal signal loss over longer runs and a safe, low-smoke in-plenum fire safety profile. The white jacket aids visibility and organization within ceiling spaces or walls where aesthetics and safety are important.
Note: Repeated Product Link Tip
For any product sections above, avoid duplicating links outside their dedicated sections to maintain clean, user-friendly navigation and comply with listing policies. The variety shown demonstrates how different brands meet CL3P/Plenum requirements while offering shielding, OFC, and long-run options for common American low-voltage applications.
Buying Guide: Key Considerations for 16/2 Plenum Cables
- Plenum rating and safety: Look for CL3P or CMP ratings to ensure safe use in air-handling spaces and adherence to NEC Article 300-22 and related guidelines.
- Conductor material: Oxygen-Free Copper (OFC) minimizes resistance and signal loss over distance, especially in longer runs.
- Shielding: Shielded variants (foil/shield or Mylar) help reduce EMI, improving performance in environments with electrical noise.
- Jacket and color: A low-smoke, flame-retardant jacket (often white) helps with visibility, fire safety, and code compliance in commercial spaces.
- Length and installation: Choose length with some extra to accommodate routes, turns, and future expansion. Longer cables may incur more resistance, so OFC helps offset this.
- Certifications: UL-listed products and compliance with local building codes minimize risk and simplify inspections.
- Applications: Confirm suitability for speaker, intercom, alarm, or data signaling, and ensure compatibility with devices and systems in your installation.
- Durability and handling: Stranded conductors are generally more flexible and easier to install than solid-core equivalents, reducing potential damage during routing.
