loudspeaker ideal for use in business music systems.
When used together with the SP800S subwoofer as a
three-way system, a unique internal filter circuit allows
the SP400 to operate as a band-limited complement to
the subwoofer. With the filter bypassed, the SP400
operates as a full bandwidth, stand-alone product.
Speaker zones can be intermixed, a
