Designed to reproduce high frequencies up to 40kHz, and so eminently suitable for reproducing high-resolution audio, the LS-301 is the ideal partner for the AI-301DA pre-main amplifier. A high-resolution sound source, offering sound quality far superior to CD, demands an equally talented loudspeaker. In a coaxial design, where the woofer - emitting powerful kinetic energy - and the tweeter - emitting high frequency sound - are both mounted on the same framework, that framework needs to be sturdy with extremely inert. The Air Direct Center Pole System does a brilliant job of converting the kinetic energy from the woofer into cone movements that deliver sound. However, just as importantly, the system also suppresses and minimizes its own effect upon the tweeter, so allowing the HF driver to work at its best. The woofer uses a pulp cone that's been enhanced with a special resin coating to reproduce heavy, low-pitched frequencies with unusual depth. In the crossover network, a film condenser is used to achieve higher level of sound quality, along with an air-core coil in the woofer. The network is carefully positioned so that it is not affected by the magnetic fields emitted by the tweeter coil.
