ULTIMA PAREJA Powerful and compact but packed with excellent clarity and dynamics, and constructed using 18mm MDF panels for extra rigidity, supported by the extensive use of internal damping pads to eliminate unwanted resonances. The drive units has a 19mm low modulus polyamide dome HF, which is offset on the baffle to reduce diffraction effects, and a powerful 150mm diecast bass chassis, furnished with a woven carbon fibre cone and a Kapton voice coil former, wound with copper coated aluminium wire. This special bass unit also has a shaped pole piece to give greater linearity of movement. Careful measurement and tuning of the reflex enclosure is combined with this excellent driver combination to provide bass extension below 50Hz, and smooth transition between the drivers is provided by a minimalist crossover which uses only top grade components, chosen for their sonic capabilities. The result is a crisp, clear sound with good dispersion characteristics and a powerful, solid overall feel.
