Power needed
30–100 W
per channel, into 4 ohms
To hit 95 dB peaks at 3 m from a pair of Emotiva Airmotiv T-Zero+, you need at least 30 W a channel. More than 100 W is wasted here — that is all Emotiva rates the speaker to take.

- 95 dB target at the seat
- +4.8 dB for 3.0 m of distance
- -3 dB for a stereo pair
- -82.0 dB effective sensitivity
- 3.0 dB taken off to convert the 4 ohm 2.83V rating to dB per watt
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 87 dB, used as 82.0 dB per watt.

45 power amplifiers that would also drive them
Listed separately because they are not a complete system: a power amplifier has no volume control and no inputs to speak of, so you need a preamplifier or a streaming preamp as well. Worth it if you already own one, or if you want to buy the two halves separately.

Excellent match
5 dB of headroom over what this speaker needs - peaks stay clean.
Has a 4 ohm tap, which is exactly what this 4 ohm speaker wants. Taps: 4 / 8 ohm.
A valve amplifier makes the same power on each tap, so what matters is sensitivity - and at 82.0 dB this speaker is efficient enough that 100 W is comfortable.
Far more expensive than the speakers. Spend it on speakers first.

Sensitivity and impedance figures are the manufacturer's own. We read sensitivity as dB at 2.83 V/1 m and take 2 dB off it, because published figures run high. Treat the result as a well-founded starting point, not a measurement. Full Emotiva Airmotiv T-Zero+ specs.
