The Technics SB-R1 Speaker System achieves a superlative level of sound reproduction by building around the brand's linear-phase, point-sound-source concept.The Point-Sound-Source system focuses on precise imaging through the alignment of the speaker's driver units. Wave-fronts from each unit will arrive simultaneously to the listener's ears regardless of listening position, allowing the system to sound as though there is a single sound source. The newly developed flat coaxial two-way speaker unit, combining midrange and treble drivers, works with a virtual coaxial woofer to realize a point sound source, providing smooth directional characteristics over the entire frequency range, without peaks or dips.Phase precision Driver's offer faithful reproduction of mid to high frequency sound with an all-new flat coaxial two-way drive. A low distortion 16-cm Long Stroke Woofer is capable of reproducing super-low frequencies with a dramatic reduction in distortion, giving a powerful and dynamic bass response. Each driver is house within the high rigidity entasis form cabinet which reduces undesired resonance with a 50mm thick baffle. Combining all of these features and more, the Technics SB-R1 is a reference class speaker fit for studio and personal use.
