The D3.1 is a floorstanding loudspeaker from Raidho Acoustics, sharing essentially identical specifications with the C3.2 within the same broader floorstanding catalogue. The D3.1 brings Raidho's considered engineering to a substantial floorstanding format.
Key specs that matter
Rated response spans an exceptionally wide 30Hz to 50,000Hz within plus-or-minus 3dB, matching the C3.2. Sensitivity is 88dB into a moderate 5 ohm load, also matching. Recommended amplifier power is specified as greater than 50W. At 20.0 x 123.5 x 46.5cm and 53kg, the D3.1 shares identical dimensions and weight with the C3.2.
Sound and use context
Expect the exceptionally detailed, precisely engineered character Raidho's distinctive ribbon-tweeter and diamond-cone driver technology is broadly known for, with performance matching the closely related C3.2 given the identical stated specifications.
Pairing
The moderate 5 ohm impedance and specified over-50W power suit a broad selection of amplifiers.
Alternatives
Raidho's own C3.2 shares identical specifications, worth confirming directly with Raidho what specific differences distinguish these two closely related models.
