Size the amplifier to the room
Use this as a first-pass engineering estimate for a KTV suite, club, bar, banquet hall or private AV room. It turns the room and loudspeaker basics into a power target, a shortlist of models and a configuration you can copy or download.

Quick amplifier selector
Adjust the room and loudspeaker inputs to see how the power target changes. The calculation is deliberately transparent, so you can check every assumption with our engineers.

This is a planning estimate, not a final system design. Loudspeaker impedance, coverage angle, room acoustics, processing and safety margins must be checked against the actual equipment and project measurements.
01
1. Room and loudspeakers
Room type sets a target sound level. More loudspeakers reduce the area each one covers, while a higher ceiling increases the estimated listening distance.
02
2. Transparent estimate
Target SPL + distance loss - sensitivity + headroom = required power per channel. The result is rounded up to the nearest 50 W, then matched to a compatible model.

Use the result to shortlist a model, not to place an order blind. Confirm impedance, amplifier loading, DSP crossover and protection with our team.
