The SN Series II transducers represent a unique combination of extremely
high performance and high value. The SN-18LF utilizes a medium
format 3 inch (76.2mm) diameter voice coil coupled to a computer
optimized Neodymium based permanent magnet system. This voice
coil and magnet structure combination insures very high conversion
efficiency and an excellent performance to value ratio. The SN-18LF is
an 18 inch (460mm) diameter low frequency design that has a rated
bandwidth of 40Hz to 125Hz. This bandwidth provides an optimum combination
of low frequency response and efficiency. It is common in professional
touring and fixed installation systems to filter low frequency
material below 35Hz to limit sub sonic material. The SN-18LF takes
advantage of this technique and has been designed to offer maximum
impact low frequency output in its rated bandwidth.
The SN-18LF features an aluminum rectangular geometry voice coil and
very high thermal capacity to insure high power handling and high reliability.
The combination of a light weight but very high energy product
Neodymium magnet structure and a die cast aluminum chassis produce
a very light weight design. The SN-18LF is well suited for medium format
touring systems and excellent for fixed installation designs, particularly
when the systems must be suspended. The light weight design makes
the SN-18LF ideal for portable systems as well as for flown/suspended
systems. The SN-18LF is an excellent choice for bass and sub woofer
designs. |
