Usually whenever a company tasks their development team with creating a new product whether it might be a powered subwoofer, amplifier or speaker, there are some goals or restrictions outlined during the planning stage. Perhaps a certain price point, form factor, or feature set, or there may be certain performance goals that need to be met. Often the goals set forth may be a combination of some or all of the aforementioned. If the final product is in many ways a reflection of its design goals, in the case of Paradigm’s Signature Sub 2 it appears that the design team was given directive to “push the envelope”. What emerged is a beastly subwoofer with an unusual hexagon shaped enclosure which bristles with no less than six overbuilt Paradigm designed 10” drivers sporting a collective 150lbs of motor arranged in a force cancelling array, an amplifier in need of a 240v line to produce its maximum continuous output of 4.5 kilowatts and an MSRP of a cool $8,999. Unsurprisingly, neither output headroom nor deep bass extension is in short supply here and achieving Audioholic’s Extreme room size rating was no problem for Paradigm’s top bass maker. However impressive the substantial output capabilities of the Signature Sub 2 are even more impressive were its top quality finishing, attention grabbing appearance, surprisingly compact size and squeaky clean sonic performance with its contribution always remaining implacably neutral regardless of material or output level demands. Paradigm’s Signature Sub 2 provided a powerful, dynamic and engaging low end presence with reference quality and quantity, proving itself to be a truly statement level product.
