The new 7” “Spider” cone bass drivers (used as Ultra Low Frequency, drivers on the Beethoven Concert Grand), able to produce increased in output, extension and control. While the new 5” Spider cone mid-bass/bass driver takes advantage of the revisions developed for the 7” driver. With the introduction of this unit, dramatic improvements in bass output and extension were achieved, while simultaneously improving midrange clarity and detail.

     The new 6” midrange driver developed with a proprietary mixture of TPX, the base thermoplastic used in all XPP cones, and two polypropylene based synthetics to achieve maximum inner damping. This new polymer, dubbed X3P allows the driver to provide an extraordinarily wide bandwidth, while possessing a level of detail and control that is truly remarkable.

     And last the new tweeter employed was developed in conjunction with Scan Speak. The result of this collaboration is a tweeter with greater resolution of the subtlest of high frequency impulses while maintaining the renowned midrange warmth and clarity of the previous design.

Crossover
     The new linear crossover design is being implemented to allow more efficient transfer of signal to the drivers. New gold-and-silver alloy terminal for lowest transfer resistance and durability and proprietary cabling, consisting of large scale, hollow core solid copper conductors used throughout the speaker.
