Coastal Source

At Suess Electronics, we believe your outdoor spaces should be just as inviting, immersive, and functional as the inside of your home. That’s why we’re proud to be a trusted Coastal Source dealer, bringing premium outdoor audio and lighting solutions to homeowners in Northeast Wisconsin. Whether you’re looking to transform your backyard into an entertainment oasis or simply enhance the beauty and safety of your property, Coastal Source delivers industry-leading performance, durability, and design.

Why Coastal Source?

Coastal Source is a pioneer in high-performance outdoor audio and lighting, designed to withstand the toughest environments while delivering unparalleled sound and illumination. Unlike other brands that adapt indoor products for outdoor use, Coastal Source engineers every product from the ground up to handle heat, cold, moisture, and debris—making them perfect for Wisconsin’s unpredictable weather.

Unmatched Durability: Built to Last

One of Coastal Source’s biggest differentiators is its commitment to durability. While many outdoor audio and lighting manufacturers use lower-grade materials that can corrode, fade, or fail over time, Coastal Source designs its products to last for decades in even the harshest conditions. Every product is built using marine-grade, corrosion-resistant materials—such as solid brass, stainless steel, and specially engineered composite materials—to withstand exposure to salt, snow, rain, and extreme temperatures.

Key durability features include:

• 100% Sealed Systems – Coastal Source audio and lighting products are completely sealed to keep out moisture, dust, and debris, ensuring long-term performance.
• Marine-Grade Construction – Unlike powder-coated aluminum or plastic components used by other brands, Coastal Source fixtures and speakers are crafted from solid brass and stainless steel for maximum longevity.
• Direct-Burial Cabling – Heavy-duty, waterproof wiring ensures connections stay intact even in the most challenging outdoor conditions.
• Rigorous Testing – Every product undergoes extreme weather simulations, from freezing conditions to high humidity, ensuring reliability year-round.

Outdoor Audio: Concert-Quality Sound in Your Backyard

Coastal Source’s outdoor audio solutions redefine what’s possible for open-air entertainment. Their bullet speakers, line array systems, and buried subwoofers work together to create rich, powerful sound that fills your yard without disturbing the neighbors. Unlike Bluetooth or portable speakers, these systems provide evenly distributed audio with incredible clarity and depth, even at lower volumes.

Key outdoor audio products include:

• Bollard Speakers – Beautifully designed with full-range sound, these speakers blend seamlessly into your landscape. They come in multiple sizes and finishes to complement any outdoor aesthetic while delivering crystal-clear highs and deep bass.
• Line Source Speakers – A revolutionary way to project clear, immersive audio across large outdoor areas, these speakers are ideal for poolside listening, patio gatherings, and outdoor theaters. Their unique design provides long-range audio coverage with minimal sound loss.
• Subterranean Subwoofers – Hidden underground for deep, rich bass without disrupting your aesthetics. These weatherproof subwoofers ensure a balanced, powerful low-end that enhances the listening experience without taking up visible space.
• Modular Systems – Whether you’re enhancing a small patio or a sprawling backyard, Coastal Source audio systems are fully scalable, allowing homeowners to start with a single zone and expand as needed.
• Landscape and Wall-Mounted Speakers – Designed for ultimate flexibility, these speakers provide directional sound where you need it most, ensuring even coverage across your entire outdoor space.

Outdoor Lighting: Beauty, Safety, and Security

Coastal Source outdoor lighting isn’t just about visibility—it’s about creating ambiance, highlighting architectural features, and enhancing safety. Their fixtures are built from solid brass for longevity and are designed to withstand Wisconsin’s temperature swings, snow, and rain without corroding or failing over time.

Key outdoor lighting products include:

• Path Lights – Elegantly illuminate walkways and garden paths, offering both functionality and charm while ensuring safe passage during evening hours.
• Bullet Lights – Perfect for highlighting trees, sculptures, or home facades, these fixtures offer adjustable brightness and beam angles to create dramatic outdoor effects.
