Sony SS-M9ED

Sony SS-1ED

may 1999

2002

Extended Definition loudspeaker designed by Dan Anagnos of Polk Monitor - with a lot of exclusive Sony technologies.

The SS-M9ED is a made in USA 60kg bass-reflex little monster with a demanding efficiency of 86dB sporting superlative structure and componentry and a complex SS-TW100ED super-tweeter extending the frequency response to... 100Khz !
The original, non-ED version, SS-M9, omits the super tweeter for a "regular" bandwidth and a pair of "regular" ears.

The SS-M9ED was named SS-1ED in Japan and was also available in microscopic quantities without the piano-black finish (much better).

The smaller but tuly excellent siblings of the series (SS-M7, SS-M5, SS-M3) were, for once, export only and they were designed and made in USA as well anyway.

The total production run of the M9ED / 1ED is anybody's guess but probably was equivalent to that of the SS-GR1. In other words : near non-existence...

Real SS-TWs here.
