I had been interested in the built-in speaker system Bose 191. Wanted to install in the kitchen ceiling. At the listening I'm specially driven into Bosestudio to Stuttgart. What there but came out of the wall was really disappointing. Rattling dull sound without any detail resolution. Since I have been an Acoustimass 10 and a Companion 5 Bose, I was there really used other sound. I already have 18/2 installed in the ceiling in the bathroom, the Visaton DL, this speaker is especially suitable for damp locations. The Visaton sound is worlds away from the Bose 191 and costs 1/5. The 191 is definitely not a figurehead for Bose - a pity!
