Outdoor Audio · Weatherproof

Outdoor audio that survives Houston heat.

Houston's climate is brutal on outdoor electronics. From late spring through early fall, Houston sees sustained 90°F+ temperatures, high humidity, heavy afternoon thunderstorms and strong UV that degrades speaker cones, gaskets and grilles. Inexpensive consumer outdoor speakers often fail early here: cones crack, grilles rust, voice coils corrode and connections turn green from moisture.

The right outdoor audio system, properly installed, will survive 8–10 years in Houston's climate. But "the right system" means more than just buying weatherproof speakers — it means selecting the right products, placing them correctly, running the right wire, and protecting the amplification gear.

What to look for in outdoor speakers

• IP rating: IP54 minimum (dust and splash resistant). IP66 or IP67 for speakers exposed to direct rain — these are rated for powerful water jets and temporary immersion.
• UV-resistant materials: Polypropylene cones, UV-stabilized ABS or aluminum grilles. Rubber surrounds degrade in Houston sun; butyl rubber lasts longer.
• Sealed enclosures: Vented speakers trap moisture and corrode from the inside. Fully sealed enclosures with drained drivers prevent condensation buildup.
• Marine-grade components: Speakers designed for boats — like the Definitive Technology AW6500 or Bose 251 — handle humidity better than standard outdoor speakers.
• Stainless or brass hardware: Standard steel mounting hardware rusts within a single Houston summer. We use only stainless steel mounting brackets and brass binding posts.

Placement for outdoor sound

Outdoor sound is harder to get right than indoor sound because there are no walls to contain it. Sound drops off quickly in open air, and you're always competing with ambient noise — cicadas, pool pumps, AC condensers, and neighbors.

• Distribute speakers evenly along the perimeter — don't cluster them in one corner
• Aim speakers toward the listening area, not toward the neighbors
• Use more speakers at lower volume rather than fewer at higher volume — 6 speakers at moderate volume sounds better than 2 speakers at high volume
• Elevate speakers when possible — ground-level speakers lose high frequencies quickly. Mount at 8–10 feet under eaves or on pergola posts
• Keep speakers at least 2 feet from the roofline — heat radiating from shingles can exceed 140°F in Houston summer

Underground speakers and landscape audio

For higher-end installations, we install subterranean speakers (like the Origin Acoustics SubTerrain or Bose Free Space in-ground) that project sound from planter beds and garden borders. These create immersive sound that seems to come from everywhere and nowhere — perfect for pool areas in Memorial, Cinco Ranch, or The Woodlands.

Amplification and wiring

The speakers are only half the equation. The amplifier needs to be indoors — never in an outdoor cabinet, even a "weatherproof" one. We run direct-burial speaker wire (UV-rated, gel-filled, rated for underground conduit) from the amp to each speaker location. For runs over 100 feet, we use 14-gauge or 12-gauge wire to minimize resistance loss. All connections are soldered and heat-shrinked — never wire-nutted, which corrodes in Houston humidity.

We typically use Sonos Amps or a dedicated multi-zone amplifier like a Russound C-Series or Niles SI-275 for outdoor zones. The Sonos Amp is our go-to because it integrates with the rest of the whole-home audio system, includes a 70V output for long runs, and can be grouped with indoor zones for parties.

What survives and what doesn't

• Survives: Origin Acoustics, Sonance, Definitive Technology AW series, Bose Free Space commercial, any IP66-rated speaker with brass hardware
• Doesn't survive: Inexpensive consumer "outdoor" speakers, any speaker with steel grilles, any speaker with paper cones, any installation with exposed wire-nut connections
• Warranty: Good outdoor speakers carry 5-year warranties. Weather-rated speakers with brass or stainless hardware, installed correctly, last far longer than inexpensive consumer models.
