Indoor Outdoor 3-Way Speaker Set

This six-speaker pack uses traditional passive design so any amplifier or receiver with raw wire outputs can drive them. The 3-way layout pairs a 4-inch silver poly woofer with a 2-inch mylar dome midrange and a half-inch mylar dome tweeter for full-range coverage. Frequency response spans 37Hz to 20 kHz at 99dB sensitivity and 8-ohm impedance. Each cabinet measures 7.375 x 4.625 x 4.125 inches and ships with U-mount brackets and hardware.

Sustained Output And Power Handling

The manufacturer rates the system at 1200 watts total while specifying 20 to 300 watts per channel from the connected amplifier. Staying within that window lets the drivers maintain their rated response during extended listening sessions without thermal compression. The sealed ABS enclosures and butyl rubber surrounds help dissipate heat so performance remains consistent across long playback periods. CL3 or raw speaker wire completes the signal path from amp to each speaker.

Weatherproof Build And Daily Mounting

Cabinets are rated durable and weatherproof against rain, snow, sun and ice for permanent patio, deck or poolside installation. Black ABS sealed construction resists UV degradation while spring-loaded raw wire connectors accept stripped cable without tools. Included U-brackets allow adjustable aiming on walls or ceilings and the compact footprint fits tight soffits or corner positions. The package suits home theatre surrounds, whole-house audio and commercial background music systems.

Questions about this item

How much heat or noise do these passive 251B speakers add when they run all day?

The 251B speakers are passive units with no built-in amplifier or fan, so they produce no electrical noise and generate negligible heat during continuous use.

What amplifier power and wiring do I already need to drive these 251B speakers?

You need an amplifier or receiver with raw speaker-wire outputs delivering 20 to 300 watts per channel at 8 ohms, plus CL3-rated or standard speaker cable for the connections.

Will the 251B set work alongside my older 8-ohm bookshelf speakers in the same zone?

Yes, each 251B presents an 8-ohm load and 99 dB sensitivity, so they can share a zone with other 8-ohm speakers driven from the same amplifier channels.
