Monitor Speakers - most sensitive
I'd like to find out what monitor (bookshelf) speaker models are out there that are very easy to drive with high sensitivity. I'm inquiring for any price range as long as they are very good sounding. Are there monitor speakers that have sensitivity above 90? I haven't seen any.
