Every speaker,
every number.

Continuous (RMS) power is the design figure. Peak is a brief transient rating, is less rigorously defined, and is a larger number — so it is the one more often quoted in marketing. Comparing one product’s peak to another’s RMS is not a like-for-like comparison. Every figure in this table is RMS.

A frequency range without a ±dB tolerance is close to meaningless, because frequencies reproduced very quietly can still be counted in the range. A narrower range quoted at ±3dB is a stronger claim than a wider range quoted with no tolerance at all.

Each 3dB of sensitivity is worth roughly a doubling of amplifier power, so a 96dB speaker reaches the same level as an 86dB speaker on about a tenth of the power. For real loudness in a large or open space, sensitivity is usually the more predictive number — provided both are quoted at 1W/1m.

Compare stated mounting depth to the cavity you actually have after services, insulation and structure — not to the nominal stud or joist size. And for outdoor use, look for a specific IP figure; “weather-resistant” without a rating is not a verifiable claim.
