Research in progress
Research is still in progress.
A passive speaker Form can remain in service as electronics and drivers are separately serviceable, but room and taste remain explicit limits.
What we were looking for
Passive loudspeakers for long-horizon living-room listening, driven by an external amplifier and judged for serviceable cabinet, crossover, driver, and parts behavior.
Why the decision is still open
The Heresy IV is a serious candidate for a passive, high-efficiency living-room Form. The case must compare cabinet, driver, crossover, service, room interaction, and counter-cases without pretending one voicing is universal.
What prevents a clear pick
- Integrated amplification, sealed electronics, unavailable drivers or crossover parts, unserviceable cabinet, and treating room preference as objective failure.
What a qualifying product must do
- Define room and listening Form, verify service parts and model identity, and evaluate serious counter-cases independently.
What can go wrong
- Driver or crossover failure, cabinet damage, terminal failure, grille wear, and mismatch to room or listening Form.

What has been examined so far
We separate source material from our interpretation. A source page can establish model identity; it does not, by itself, prove that a product deserves the pick.
