The Raidho Acoustics X3 and X3T are a 2.5-way Raidho loudspeaker designs. The X3/T is equipped with four dedicated 4-inch ceramic, ceramic/titanium mid-bass drivers and one 8-inch side-mounted bass driver. Central is the Raidho Acoustics’ one-of-a-kind sealed-ribbon tweeter that employs an array of neodymium magnets to create an extremely powerful force field, in which an ultra-thin membrane is suspended. The weight of the membrane in the Raidho ribbon tweeter is less than 0.02 grams. Due to the low membrane mass, the tweeter stores no energy and has no resonances.
