Active vs. Passive Speakers

A speaker system must split the signal into bands — bass to the woofer, treble to the tweeter. The only question is where that split happens.

Passive: the split after the amplifier

In a passive speaker, one external amplifier feeds the whole thing, and a network of coils, capacitors and resistors inside the cabinet splits the power between drivers.

Advantages:

• One amplifier serves the whole system; upgrade paths are separate.
• The speaker is simple to build and repair — no electronics inside.
• You can pair any amplifier with any speaker (for better or worse).

Costs:

• The crossover must handle full power; components get big and lossy.
• The amplifier sees the crossover’s messy impedance, not the raw driver.
• Corrections are fixed by hardware — re-voicing means re-soldering.

Active: the split before the amplifier

In an active design, each driver gets its own amplifier channel, and the split happens at line level (or in DSP) before any power is involved.

Advantages:

• Each amplifier sees the driver directly — no coils in series, ideal damping.
• Crossover slopes, delays and EQ become software: re-voicing is a preset.
• Amplifiers can be sized per driver instead of worst-case.

Costs:

• Amplifiers, power supplies and heat live inside the cabinet.
• The product boundary moves: you buy a complete system, not mix-and-match pieces.
• Repair is electronics repair, not just driver replacement.

Where Tikpal stands — for now

Our first generation is passive speakers with an external amplifier, with DSP presets available in the amplifier for room and placement correction. That keeps every piece of the chain upgradeable and repairable separately while still capturing most of the correction benefit of active designs.

Whether a future product crosses into fully active designs is an open engineering question — and exactly the kind of thing the Lab exists to answer with data instead of dogma.
