I'm on the fence on this one, I used to install Bose Acoustimass 5 loudspeakers in both domestic HiFi systems and commercial applications, i.e. pubs, Hotels e.t.c. I liked them but not enough for me to buy them.
I have to admit, whilst they sounded brilliant in commercial situations (think Zavvi Shops e.t.c) they were less impressive in home HiFi systems, I found they needed a lot of driving and you definitely needed an amp that had tone controls so you could balance the bass and treble out. Also I found a lot of customers preferred them when using the "Loudness" button.
IMHO Bose products are a little to over priced than they should be, but people who loved them, bought them, those who didn't love them, didn't.
Again it is the same fundamental rule, use your ears, not anyone else's to decide if you like a system or not.
