15″ FRX Hats are a pro-level B20 Bronze pairing that delivers exceptional versatility, clean sticking and crisp response. SABIAN FRX (Frequency Reduced) cymbals are designed for playing environments where other cymbals have too much attack. They are NOT low volume cymbals. Rather, they work by cutting specific frequencies that result in the perception of volume. Remove those frequencies, and suddenly 15″ FRX Hats sit perfectly in the mix, no matter how hard you play. No compromise – no holding back. FRX are ideal for playing churches, weddings, corporate gigs, small venues, schools, musical theater, cruise ships, drummers who sing, band rehearsals, or any setting where cymbal volume could be a problem: even on the largest stages where a multitude of live mics for singers and acoustic instruments are a challenge. FRX gives real drummers in real situations the freedom to play any gig without holding back.
