DESCRIPTION
•Compact 2-way 12-inch Stage Monitor / PA
•Less than 15 inches high for low profile applications
•Rubber feet included for floor mounting
•PassiveEQandcrossoverforeconomicalsingleamplifieroperation
•Foam-backed steel grille for physical and dirt protection
(foamnotshownin photo)
The SM129zi is a compact, professional loudspeaker designed for
dual-purpose stage monitor and PA use. Its 12-inch low frequency
transducer provides strong LF performance while keeping a small
enclosure size for situations with limited space. The smooth HF
response and high output capability cuts through stage sound for
qualitymonitoringandprovides goodprojectionforPAuse.
The low profile and compact size are ideal for situations where small
physical size is needed, without sacrificing professional
performance. Integral mounting points accept a third-party, external,
stand adapter for pole mounting, such as the K&M™ 195/8 or
UltimateSupport™BMB-200K.
Portable usage is enhanced by the heavy-duty enclosure
construction, foam-backed steel grille, and integral handles. The
connector panels on each side have dual jacks for reliable input and
loopthroughconnections.
Applications include use as a stage monitor or as a PAloudspeaker
for band PA, TV productions, corporate events, theatres, houses of
worship,andlivemusic clubs.
Sixyearwarranty.
