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.\u003c\/p\u003e\n\n\u003ch3\u003eHow will these tweeters change the sound of my marine audio setup?\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e1\" titanium dome tweeter for extended high-frequency response\u003c\/li\u003e\n  \u003cli\u003e2 kHz–25 kHz range to cover detailed treble content\u003c\/li\u003e\n  \u003cli\u003eFerrofluid cooling to improve thermal handling and reduce compression\u003c\/li\u003e\n  \u003cli\u003eSwivel housing to aim highs precisely toward listeners\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these tweeters survive a marine environment and frequent use?\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum bullet-horn housing for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHigh-temperature 1\" voice coil tolerates prolonged use\u003c\/li\u003e\n  \u003cli\u003eMetal swivel bracket for adjustable and secure mounting\u003c\/li\u003e\n  \u003cli\u003eIncludes hardware and caps for straightforward installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do these tweeters install and match with my existing system?\u003c\/h3\u003e\n\u003cp\u003eInstallation 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eComes as a matched pair with installation hardware included\u003c\/li\u003e\n  \u003cli\u003eWorks with typical marine amplifier outputs and head units (4 ohm impedance)\u003c\/li\u003e\n  \u003cli\u003eCompensation capacitors help protect and blend the tweeters with woofers\u003c\/li\u003e\n  \u003cli\u003eSwivel housing simplifies directional aiming and alignment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat performance numbers and specs should I expect?\u003c\/h3\u003e\n\u003cp\u003eThe 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.

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.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are these tweeters waterproof?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: They use corrosion-resistant aluminum and durable parts but are not fully sealed waterproof; designed for marine-rated installations, avoid direct prolonged water immersion.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will they work with my 4 ohm amplifier?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
