Raidho Acoustics have built on the success of their flagship TD4.8, they have adapted the technologies to create the TD4.2.  It uses their acclaimed Tantalum-Diamond-drivers and the updated ribbon-tweeter.

By adding the Tantalum-coating to the already excellent Diamond-drivers, Raidho have achieved a cone which is even stiffer. The cone consists of 5 layers with even higher levels of inner damping. In combination with the upgraded magnet system with the new SD-cap, stronger magnets and better voicecoil, the TD4.2 will give the qualities of the TD4.8, but in a size that is a little more room friendly.

The tweeter also is upgraded with a more powerful magnet system, making it more sensitive, but with the same open and detailed sound that is a Raidho-trademark. The internals of the cabinet have also been improved, resulting in deeper frequency response and a sound that is more natural while providing a huge soundstage.
