Speco SPP20T Passive Projection Speaker 70V Transformer

Product Description

The SPECO SPP20T is a passive projection loudspeaker with an integrated 70-volt transformer, designed for distributed audio installations in commercial and institutional environments. The 5.25-inch driver delivers focused sound projection suited to ceiling or wall mounting in spaces that require consistent coverage without active amplification at the speaker location. A licensed audio installer or low-voltage technician typically handles the wiring and system commissioning. The built-in 70V transformer allows this speaker to be wired in parallel on a constant-voltage distribution line, simplifying multi-speaker runs across large facilities.

The SPP20T is well suited for background music, paging, and public address applications in retail spaces, schools, offices, houses of worship, and similar commercial settings. It is sold as a single unit and integrates into standard 70-volt distributed audio systems where the amplifier handles the line-level voltage step-up. Installers working on larger zoned audio systems will find the 70V transformer format compatible with most commercial-grade constant-voltage amplifiers.

Key Features

• 5.25-inch projection speaker driver for focused, directional sound coverage
• Integrated 70-volt transformer for direct connection to constant-voltage distribution systems
• Passive design eliminates the need for a local amplifier at the speaker
• Single-unit packaging suitable for scalable multi-speaker distributed audio runs
• Compact form factor supports ceiling and wall mounting in commercial spaces

Compatibility

Designed as an OEM-style replacement or new-installation passive loudspeaker for 70-volt constant-voltage distributed audio systems in commercial and institutional settings.

Installation Notes

Installation should be performed by a licensed low-voltage technician or audio systems installer familiar with 70-volt distributed audio wiring practices. De-energize the amplifier and distribution line before making any speaker connections. Follow applicable NEC low-voltage wiring guidelines and local code requirements for in-wall or in-ceiling cable routing. Do not connect this speaker directly to a standard 4-ohm or 8-ohm amplifier output without a compatible impedance-matching transformer.
