arched cabinet sides the arch shape creates non-parallel sides preventing internal resonances that muddy the sound internal trusses cross-braces span the entire length of the arched sides creating an extremely rigid cabinet structure that virtually silences unwanted vibrations bessel function tweeter array in the ls360 and cs350 the individual tweeter amplitudes and phase relationships are adjusted so that the array acts as a high frequency point source with a broad dispersion pattern the array also greatly increases power handling for high frequencies precision crossovers designing the optimal crossover for any speaker is a challenge to do so for several and make them sound like a true family is more like an art and this is exactly what mcintosh has done ld/hp® drivers in a ld/hp driver a pair of aluminum shorting sleeves makes the magnetic field more symmetrical and reduces distortion the sleeves also lower the impedance of the voice coil permitting greater current flow and hence higher output levels hand-crafted drivers woofer and midrange cones are constructed of polypropylene which has a high stiffness-to-mass ratio and good damping properties rubber surrounds ensure linear cone excursion and like the cones are immune to decay drivers are mounted in proprietary die-cast aluminum frames and undergo rigorous tests in mcintosh s anechoic chamber flared ports the ports in the ls360 ls340 and ps112 have flares at both ends to minimize air noise with high levels of bass.
