Indoor/Outdoor Passive Speakers

The Acoustic Audio 251B set delivers four passive speakers built for indoor and outdoor use. Each cabinet houses a three-way driver array with a four-inch woofer, two-inch midrange and half-inch tweeter. They suit home theatre surrounds, whole-house audio or patio installations where weather resistance matters.

Amplifier And Wiring Check

Your amplifier or receiver must supply between 20 and 300 watts per channel into raw speaker wire outputs. The speakers present an eight-ohm load and require CL3-rated or standard raw speaker cable for the runs. Verify that your amp can drive this impedance and power range before connecting the pair.

Weatherproof Cabinets And Mounting

Black ABS sealed enclosures resist rain, snow, sun and ice for year-round outdoor placement. Spring-loaded raw wire terminals accept bare conductor ends without tools. Included U-brackets with hardware allow wall or ceiling mounting at the supplied dimensions of 7.375 by 4.625 by 4.125 inches each.

Questions about this item

What comes in the 251B-2Pr pack and what else do I need to buy?

The pack contains four passive speakers, mounting brackets with hardware, and an instruction manual. You must supply an amplifier or receiver with raw speaker wire outputs and CL3 or raw speaker wire to connect them.

How do I choose between the 800-watt label and the 20-to-300-watt per channel requirement?

The 800-watt figure is the system peak rating for all four speakers combined. Each speaker needs an amplifier delivering between 20 and 300 watts per channel at 8 ohms, so select an amp that falls in that range.

What does the 99 dB at 8 ohms sensitivity mean for real-world volume?

At 99 dB sensitivity, each speaker produces loud output with modest amplifier power, so a typical home receiver can drive them to high listening levels without strain.
