I recently read a post online that Quad introduced new speakers, the 2812 & 2912, at the last show in Munich. Would you know if the 2805's will be discontinued?

The US importer, Taiga LLC has closed shop. At this time, Liberty Trading, run by May Audios' Canadian counter-part is the sole NA importer. Also, prices have increased.

It would appear that the 2805 are still available
