Tweeter and Woofer Crossover

Every multiway spekar must have a crossover.The tweeter handles the highs the woofer the lows. Each must be divided according to their abilities. Safe crossover points and careful attenuation ensures clarity and natural - accurate sound without harshness or fatigue. This sets your tweeter where it performs best.

Understanding Crossovers

A crossover is the traffic cop of a loudspeaker system. It decides which frequencies go to the woofer and which go to the tweeter, ensuring each driver plays only the range it was built for.

How It Works

• High-pass filter: blocks low notes from reaching the tweeter, which could damage it or cause distortion.
• Low-pass filter: blocks high notes from reaching the woofer, preventing muddiness and breakup.

Most speaker systems use a 2nd-order (12 dB/octave) crossover. This slope is steep enough to protect the drivers, while still maintaining good phase alignment between woofer and tweeter.

Why It Matters

Without a proper crossover, drivers overlap awkwardly, causing peaks, dips, or even damage to delicate tweeters. With the right crossover, the handoff is seamless, giving you clean, balanced sound.

👉 Use the Tweeter Generator to calculate both halves of your crossover automatically, matched to your tweeter’s Fs and woofer size.
