There is a great degree of similarity in the design and execution of our different loudspeaker models. We have integrated our best efforts into each system that we build, and the primary difference between models is their deep bass extension and ultimate sound pressure capabilities. All of these models exhibit a marked family resemblance, but are suited for different size rooms and listening levels. The exquisite build quality and stunning performance of every Rockport Technologies product, from our most ambitious to our most affordable, is evidence of our commitment to excellence.
