Pyramid Marine Tweeter Speakers 3.75" Aluminum Horn

The Pyramid TW28 is a pair of 3.75" aluminum bullet-horn marine tweeters with 1" titanium dome drivers, a heavy-duty 20 oz magnet structure and a 2 kHz–25 kHz frequency range designed to add crisp high-frequency detail to marine or outdoor audio systems.

These compact horn tweeters are engineered for boats and other marine environments where clarity and durability matter. Housed in swivel-mount aluminum enclosures, the TW28 pair combines a titanium dome for extended highs, ferrofluid cooling for thermal stability, and a robust magnet assembly for 300 watts peak output. The 4 ohm impedance helps compensate for common wiring limitations in many marine installs while keeping distortion low.

How will these tweeters change the sound of my marine audio setup?

The TW28s are focused on reproducing the upper-frequency content—vocals, cymbals and transient detail—so the overall system sounds clearer and more defined. Adding dedicated high-frequency drivers reduces strain on midrange speakers and fills in crispness lost in open-air listening.

• 1" titanium dome tweeter for extended high-frequency response
• 2 kHz–25 kHz range to cover detailed treble content
• Ferrofluid cooling to improve thermal handling and reduce compression
• Swivel housing to aim highs precisely toward listeners

Will these tweeters survive a marine environment and frequent use?

The TW28 pair uses a heavy-duty aluminum enclosure and a strong 20 oz magnet structure to resist corrosion and mechanical wear better than lightweight plastic units. While not a sealed waterproof speaker, the materials and construction are chosen for rugged marine and outdoor installations.

• Aluminum bullet-horn housing for durability and corrosion resistance
• High-temperature 1" voice coil tolerates prolonged use
• Metal swivel bracket for adjustable and secure mounting
• Includes hardware and caps for straightforward installation

How do these tweeters install and match with my existing system?

Installation is straightforward: the TW28 pair ships with mounting hardware and compensation capacitors for correct crossover behavior. The standard form factor and 4 ohm impedance make them compatible with most marine amplifiers and head units, and the swivel mount lets you aim the output for best coverage.

• Comes as a matched pair with installation hardware included
• Works with typical marine amplifier outputs and head units (4 ohm impedance)
• Compensation capacitors help protect and blend the tweeters with woofers
• Swivel housing simplifies directional aiming and alignment

What performance numbers and specs should I expect?

The TW28 pair provides a peak handling figure up to 300 watts, a nominal 4 ohm impedance, and a frequency window from roughly 2 kHz to 25 kHz—intended to reproduce upper-band detail rather than low bass. A robust magnet and ferrofluid in the gap support dynamic response and thermal stability during demanding listening sessions.

• Peak power: up to 300 watts (peak rating)
• Impedance: 4 ohm nominal for amplifier compatibility
• Driver format: 1" titanium dome in a 3.75" aluminum bullet horn
• Magnet: 20 oz heavy-duty structure for stronger motor force

Who is this for? The Pyramid TW28 tweeter pair is best for boat owners, marine audio hobbyists and outdoor audio installers who want to restore or upgrade high-frequency clarity without reworking their entire system. Choose these if you need a compact, aimable tweeter solution that pairs easily with existing woofers and amplifiers and is built from materials suitable for harsh environments.
