Philmore 4" Square Replacement Speaker 8Ω 5W

The Philmore TS45 is a compact 4-inch square replacement speaker with a weatherproof mylar cone, rated 8 ohms and 5 watts for dependable outdoor and indoor audio applications.

Designed as a direct-fit replacement or a budget-friendly upgrade, this Philmore 4" square speaker combines a moisture-resistant mylar diaphragm with a ceramic magnet to deliver consistent sound in exposed environments. Its small footprint and standard terminals make it an easy swap for panels, intercoms, outdoor clocks, landscape audio, and DIY audio projects where space and durability matter.

Will this speaker resist moisture and outdoor exposure?

The TS45 uses a weatherproof mylar cone that tolerates humidity and light exposure better than conventional paper cones, reducing degradation in damp conditions. While it's built to withstand splashes and humid spaces, it isn't intended for continuous immersion or fully exposed marine placement.

• Weatherproof mylar cone resists moisture and swelling
• Ceramic magnet provides stable magnetic performance over time
• Suitable for covered outdoor enclosures and protected outdoor fixtures

How easy is it to install in my existing device?

Installation is straightforward: the 4" square form factor fits many panel cutouts, and the unit accepts solder connections as well as .187" quick-connect terminals for fast hookups. Because it’s a direct-replacement style speaker, you can usually swap it without modifying the mounting or wiring.

• Standard square dimensions for drop-in replacement projects
• Solder lugs plus compatibility with .187" quick-connects
• 8 ohm impedance matches common consumer and low-power amplifiers

What kind of sound and power handling should I expect?

The TS45 is a low-power speaker rated at 5 watts RMS and 8 ohms, optimized for clarity at moderate listening levels rather than high-output bass. It performs well for voice, alerts, background music, and system notifications where fidelity and reliability are more important than high SPL.

• 5W power rating for low- to moderate-volume applications
• Balanced response for speech and simple audio playback
• Compact 4" cone suited for tight spaces and enclosures

Who should choose the Philmore TS45?

This speaker is a practical choice for anyone replacing worn or damaged small speakers in outdoor-rated fixtures, intercoms, wall clocks, landscape audio units, or DIY enclosures. It serves installers, hobbyists, and technicians who need a reliable, weather-tolerant 4" square driver with easy connectivity and modest power requirements. If you need a high-output or subwoofer-grade driver, consider a larger or higher-wattage alternative; for compact, durable audio in constrained spaces, the TS45 is a solid match.
