Acoustic Audio by Goldwood 251B Outdoor/Indoor 3-Way

Acoustic Audio by Goldwood 251B are compact, weather-resistant 3-way passive speakers that deliver full-range sound indoors or outdoors when connected to an amplifier or receiver.

These Acoustic Audio 251B speakers pair a 4" woofer, 2" midrange and 0.5" tweeter in a sealed black ABS cabinet designed for patios, retail spaces, home theater surrounds and whole-house audio. They are passive (require an external amp), mount easily with included U-brackets, and are built to withstand rain, sun and cold while maintaining a wide 37 Hz–20 kHz frequency range and high sensitivity.

How do these speakers perform outdoors and resist the elements?

The 251B enclosures are sealed ABS cabinets with weatherproof components and spring-loaded raw wire connectors that minimize moisture intrusion. While not fully submersible, they are engineered to tolerate rain, sun exposure, snow and freezing conditions for typical outdoor audio setups.

• Black ABS sealed cabinet resists UV and moisture.
• Spring-loaded connectors reduce oxidation risk.
• Included mounting brackets keep speakers secure on walls and eaves.
• Compact size eases placement under overhangs or on posts.

What audio quality and power handling can I expect?

The three-driver design (woofer, midrange, tweeter) provides fuller frequency coverage than two-way boxes of similar size, yielding clearer mids and defined highs alongside punchy low-end for its class. Sensitivity and crossover design allow the pair to reach high sound levels without demanding extreme amplifier power.

• 4" silver poly woofers with butyl surrounds for tighter bass.
• 2" mylar midrange and 0.5" mylar tweeter for vocal and treble clarity.
• Frequency response: 37 Hz–20 kHz; rated at 99 dB (8 ohm).
• Accepts 20–300 watts per channel from your amplifier.

How easy is installation and what equipment do I need?

Installation is straightforward: run raw speaker wire from any amplifier or receiver with spare speaker outputs, secure the speakers with the included U-brackets and weatherproof as needed. No special tools beyond basic wiring and mounting supplies are required.

• Connect using CL3 or standard raw speaker wire to amp/receiver outputs.
• Mount with included U-brackets and hardware—wall or ceiling compatible.
• Passive design requires an external amp or home receiver (20–300 W/channel).
• Instruction manual provides wiring and placement guidance.

Can these speakers be used in home theater or commercial spaces?

Yes — the 251B pair works well for home theater surrounds, multi-room audio, retail background music or covered outdoor entertainment areas. Their compact footprint and mounting options make them a flexible choice for many installations where weather resistance and attractive aesthetics matter.

• Ideal for patio, deck, poolside and spa audio (covered locations preferred).
• Suitable for whole-house audio wiring and multi-zone setups.
• Good fit for business/retail backdrops and small venue playback.
• Blend into décor thanks to a low-profile black finish.

Who is this for: The Acoustic Audio by Goldwood 251B speakers are aimed at homeowners and installers who need reliable, mountable passive speakers that balance compact size with full-range sound. Choose these if you plan to power speakers from an existing amp or receiver and want weather-resistant performance for covered outdoor areas, home theater surrounds, multi-room audio or light commercial installations.
