Casey, as Jason points out, contrary to what might be expected simply by looking at them, speakers with drivers aligned horizontally have good vertical dispersion, while speakers with drivers aligned vertically have better horizontal dispersion. This has been well-recognized in the industry for years and has been adopted by competitors well before this. For example, note the Paradigm line-up of center speakers
here , which use this configuration in even the less expensive models.
So, no entirely new technology is involved here, although as Ian has explained, changes, including crossover slopes, were necessary in adapting the M60 components to the W T/M W configuration.
