Power Dynamics BHW40BK - 4" Passive Speaker System for Indoor and Outdoor Use

The Power Dynamics BHW40BK speaker system is the ultimate audio solution for those seeking versatility, durability, and high-quality sound for both indoor and outdoor spaces. Designed to blend seamlessly into residential and commercial environments, these 4-inch passive speakers deliver crisp, powerful sound reproduction, withstanding harsh weather conditions without compromising performance. Their sleek black finish and understated design make them ideal for any décor or installation.

Built to last, the BHW40BK speakers are IPX5 certified, guaranteeing protection against low-pressure water jets from any direction. This makes them perfect for installation on patios, in gardens, around pools, or even on boats. The robust housing is complemented by a marine-grade aluminum grille, treated with an industrial-grade paint coating that prevents corrosion and wear in harsh environments. Their wide operating temperature range of -20°C to 60°C ensures reliable year-round performance.

Inside, each speaker houses a two-way system with an integrated crossover. This configuration efficiently separates frequencies, directing bass and midrange tones to a powerful 4-inch woofer and treble to a 1/2-inch dome tweeter. The result is a balanced, clear sound with excellent 120° dispersion, evenly covering the listening area.

Flexibility is one of the key features of the BHW series. Thanks to a rear rotary selector, the speakers can be configured to work in low-impedance systems (8 ohms), compatible with most home stereo amplifiers, or in 70V/100V line installations, common in large commercial spaces. For 100V line operation, it offers different power outputs (5W, 10W, 20W) that allow you to balance the volume of each speaker individually within a distributed system.

Frequently Asked Questions

What does IPX5 certification mean?

The IPX5 certification ensures that the speakers are protected against low-pressure water jets from any angle. This means they can withstand rain or splashes without issue, but they are not designed to be submerged in water.

What type of amplifier do I need for these speakers?

It depends on the installation. For a single pair at home, a standard stereo amplifier that supports 8-ohm speakers is sufficient. For larger installations with multiple speakers spread over long distances, you'll need a 100V line amplifier.

Does the mounting bracket allow the speaker to be rotated?

Yes, the included stand is specially designed to offer great flexibility, allowing you to adjust the speaker's position both horizontally and vertically to optimally direct the sound.

Does the product include one or two speakers?

The Power Dynamics BHW40BK is supplied as a set that includes two speakers.
