Power needed
3.8–60 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of Triangle Borea BR09, you need at least 3.8 W a channel. Anything from about 7.5 W to 60 W a channel is comfortable; past that, more watts stop buying you anything.
Power is not your constraint. The
Triangle Borea BR09 is efficient enough that essentially any
amplifier we list will drive it at this level. Choose on inputs, streaming, phono
stage and price instead - and if you like valve amplifiers, this is a speaker
that suits them.

- 95 dB target at the seat
- +4.8 dB for 3.0 m of distance
- -3 dB for a stereo pair
- -91.0 dB effective sensitivity
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 93 dB, used as 91.0 dB per watt.
Cambridge Audio CXA81 with the Triangle Borea BR09
Workable with care
13 dB of headroom, far more than needed. No harm in it.
Rated to 4 ohms, but this speaker dips to 3.3. Fine at sane volume, tight if you push it hard.
Power rises usefully into 4 ohms (80 W to 120 W).

Excellent match
10 dB of headroom over what this speaker needs - peaks stay clean.
Rated down to 2 ohms - stable into anything this speaker will throw at it.
Power nearly doubles into 4 ohms (40 W to 80 W) - a stiff supply that copes with hard loads.
Sensible value pick against these speakers.
2
Good match
12 dB of headroom, far more than needed. No harm in it.
Rated down to 2 ohms - stable into anything this speaker will throw at it.
No 4 ohm power rating on file. On a 8 ohm speaker dipping to 3.3 that is the figure that matters, so this one is unproven on the load.
Balanced against the price of the speakers.

68 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.

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 Triangle Borea BR09 specs.
