Creating the ultimate home theatre experience demands a level of performance that goes beyond the conventional.

That pursuit of perfection has always been a mission for our engineers, and the results of that pursuit can now be experienced with our Pioneer CST line as well.

With the immediate installation benefit of virtually disappearing into any environment, the quality of the sound that follows certainly makes its presence known.And with Coherent Source Transducer (CST) driver technology offering an even wider “sweet spot” than competing pivoting driver designs, a more consistent and uniform auditory experience is now possible for any home theatre.

With a smoother response and greater vocal clarity found in its 3-way design and high performance materials, the S-IW551L brings you even closer to the ultimate home theatre experience in a form factor designed to be used in front left/centre/right installation.

Featuring CST technology and anchored by two 5.25”mica-filled Injected Moulded Polypropylene (IMPP) woofers, a 6.5” Mica-Filled IMPP midrange and a 1.5” aluminium tweeter, this model also includes a thermal resetting protection circuit for a stable home theatre application. Add a treble control and the resulting experience is delivered to perfection.
