The Dum Bum 16s 25mm C1625DU by Klasek is a compact yet impactful fireworks battery designed for those seeking a louder, more dynamic effect than typical small recreational cakes. With its 16-shot configuration and 25mm calibre, this model is geared towards delivering a bold, concise display – ideal for those who prefer intensity over long duration shows.
This firework cake features a straightforward single-row set-up, offering powerful reports that have become a signature of the Dum Bum series. It’s certified in Category F2, making it accessible to private users with proper safety precautions. While some sources mention a display time of 25 seconds, official manufacturer information lists it closer to 15 seconds. For this reason, it’s best considered a fast-paced, robust cake, perfect for a quick, energetic highlight in your display or as a strong addition to a multi-cake show.
Although the signature effect of the Dum Bum range is its intense sound, the C1625DU model does not have an officially documented colour sequence or finale effect. As such, the focus remains on uncompromising bang and timing, rather than complex visual transitions. This makes it a straightforward option for those who value raw power and audio presence in their fireworks selection.
