Machined from a single block of 2017 Duralumin! RTP-2, 4 and 6 ultimate boxes are made from 2017 Duralumin, which has the best vibration damping characteristic and sound quality.
A machined structure has far better vibration damping characteristics, sound quality and overall lower distortion when compared with metal sheets bolted together to form a box. The box's maximum thickness is 25mm, making it able to be very highly effectively in shielding the inner structural elements, and yielding a very high S/N ratio.
The inlet wiring connection is non-solder. ACOUSTIC REVIVE avoids solder connections when possible because it destroys signal transmission.
