About the D4.1
The Raidho Acoustics D4.1 is a premium 3-way floorstanding loudspeaker developed as a smaller counterpart to the acclaimed Raidho D5. It incorporates a driver complement of 4 bass drivers, two 100 mm diamond midrange drivers, and a sealed ribbon tweeter, all developed in-house by Raidho in Denmark. The drivers utilize advanced motor technology including N52 Neodymium magnets and underhung titanium voice coils for linearity and dynamic precision, resulting in perfect transient response with minimal distortion. The enclosure is vented with a rear port, and the crossover is set at 3 kHz using 2nd and 4th order filters. The speaker offers a frequency response from 25 Hz to 50 kHz, a nominal impedance above 6 ohms, and a sensitivity of 89 dB at 2.83 V/m. It is designed for amplification above 50 watts but performs well even with smaller tube amplifiers. The cabinet is available in black piano finish, walnut burl veneer, or custom paint colors. Dimensions are 200 mm width, 1550 mm height, and 600 mm depth (440 x 1580 x 600 mm including feet), with a weight of approximately 64 kg. The D4.1 is noted for its full-range sound, impact, and refinement, making it suitable for audiophiles who prioritize musical fidelity and system optimization.
