What makes the R45 the flagship Radia floorstander?

The R45 uses a three-way design with three 165mm MCC woofers, a dedicated 165mm DCC midrange driver and a 25mm DCC tweeter in an Acoustic Lens waveguide. The larger cabinet and multiple bass drivers give it different room and amplifier considerations from the more compact R35.

ARCAM R45 – Frequently Asked Questions

How much space should I allow?

At around 112cm tall, the R45 needs a considered position, with clearance for its rear bass-reflex ports. Test spacing from walls and toe-in in the listening room rather than selecting position on appearance alone.

Is the price for a pair?

Yes. The £5,999 price is for two speakers, supplied in separate cartons.
