Bevenbi 82uF 250V MKPA-D Polypropylene Capacitor

Bevenbi Diamond Series premium audio capacitors give you high fidelity speaker performance without breaking the bank. In the audio industry the Diamond Series is considered to have the best price to performance ratio on the market. And for good reason. They offer excellent high frequency control and suitable for all audio frequencies. Made using pure polypropylene film encased with an aluminum alloy which is then coated with a fire retardant insulating epoxy. Leads are made from oxygen free pure copper wire for enhanced signal flow and then tinned for easy soldering.

The Bevenbi Diamond capacitors are a step above the yellow capped E-Series with an even lower dissipation factor of 0.0008 (0.08%) @ 1 kHz allowing them to perform equally against more expensive brands. Their quick transient design handles fast current pulses for that transparent sound characteristic you expect from top of the line audio gear. High-end speaker manufacturers like Bowers and Wilkins have relied on their superior build quality for years. Now you too can trust your next speaker project to name brand Bevenbi capacitors for all your premium crossover needs with unmatched quality and performance. Great sound starts with great components.

Why Polypropylene Capacitors Are the Gold Standard for Speaker Crossovers

When building or upgrading a speaker system, the quality of your crossover components can make a huge difference in sound clarity, accuracy, and overall performance. Among the many capacitor types available, polypropylene capacitors stand out as the preferred choice for high-end audio applications—and for good reason. Unlike electrolytic or ceramic capacitors, polypropylene caps are non-polarized, meaning they can handle AC signals without distortion, making them ideal for crossover networks where signal integrity is critical. Their low dielectric absorption ensures that transient responses (like the attack of a snare drum or the pluck of a guitar string) are reproduced clearly. Polypropylene film is also stable during temperature fluctuations, so your speakers will sound consistent whether they’re in a cold basement or a warm dedicated listening room.

Another advantage of audio grade capacitors is their ultra-low Equivalent Series Resistance (ESR) and minimal inductance (ESL). This allows them to pass high frequencies with minimal phase shift or energy loss. That's important because it's how you get tighter, more detailed highs and a smoother, more natural midrange—qualities that audiophiles and DIY speaker builders shoot for. Polypropylene capacitors also last longer, maintaining their performance over decades, unlike electrolytics that can degrade over time.

Cinergy Audio has sourced premium audio-grade polypropylene capacitors that meet the strictest tolerances. All models use pure polypropylene film and oxygen-free copper leads that are pre-tinned for easy soldering. These capacitor brands are trusted in high-end speaker designs worldwide, delivering the transparency, durability, and sonic purity that discerning builders and manufacturers demand. Whether you're fine-tuning a bookshelf system or crafting a reference-level floorstander, our polypropylene capacitors ensure your crossovers perform at their absolute best—so you hear the music exactly as it was intended.
