Notes

Loading the Fi SSD 18D2 driver into the 4.2 cubic foot sealed test cabinet results in a system with a rather peaked response and moderate to low sensitivity. That being the case it would be best to limit this unit to a frequency range below 90-100Hz or so. The SSD driver is one of the more cost effective long throw 18 drivers available currently and also happens to be at least partially made and assembled in the US. In a sealed system it provides rugged physical characteristics, reasonable low bass displacement and maximum output for a modest investment. Interestingly its distortion, while perhaps a little higher in percentage of output than some other drivers for the same output SPL, is comprised of mostly the 2nd harmonic which is considered the least offensive audibly.
