ARCAM R25 – Frequently Asked Questions

Which amplifier should I use?

The R25 is a passive 6-ohm speaker and needs an amplifier comfortable with its electrical load. ARCAM's Radia integrated amplifiers are natural audition partners, but a suitable amplifier from another brand can also be used.

Does the price include two speakers?

Yes. This listing is for a stereo pair, not one cabinet.
