A is a tool used by audio engineers and DIY speaker builders to determine the specific electrical component values—capacitors and inductors—needed to build a crossover network that yields a flat frequency response.
A well-designed Linkwitz-Riley Crossover Calculator does more than compute reactance formulas. Modern interactive versions (available on audio DIY websites and mobile apps) offer: Linkwitz-Riley Crossover Calculator
Let’s assume you are building a classic two-way bookshelf speaker. You have a tweeter rated for 40 watts and a woofer that plays beautifully up to 3,000 Hz. You decide on (F_c = 2,500 \text Hz), ( \textImpedance = 8 \Omega). We will use an slope. A is a tool used by audio engineers
| Expectation | Reality | | :--- | :--- | | "I want a sharp cut-off." | Use LR-4 (24dB). | | "My tweeter is fragile." | Use LR-4. LR-2 lets too much bass through. | | "I want the best time alignment." | Use LR-4. It has superior step response to Butterworth. | You have a tweeter rated for 40 watts
