Zeiler Audio SP-02

Matej Isak

The SP-02 high-efficiency single-point source speaker is a smaller version of Zeiler Audio’s highly acclaimed SP-01. Sharing the same driver with its bigger brother the SP-02 provides similar qualities from a much smaller enclosure. “The idea behind the SP-02 was to make the fantastic qualities of our SP-01 speaker available for music lovers with limited space. In smaller rooms and just a handful of watts the SP-02 with its 97 dB efficiency will surprise you with the full power of the orchestra.”— Ralf Zeiler. The “SP-02” loudspeakers are available in two high-quality surface finishes: piano high gloss or an elegant satin finish, characterized by its subtle, matte texture. A huge variety of colors is available to accomodate a range of design preferences, ensuring they blend seamlessly with your living environment. All NCS colors are available on request — the versions shown below are examples only and represent just a small selection of the available options.
