Mounting bookshelfs flush with ceiling - can you?

baffle step, right on the money.  
ceiling or wall speakers are best.  
for the application.
encposed speakers can work well near the ceiling on brackets but not flush.  

Tall stands, save yourself cutting through plaster. If you can't buy them the right size, find yourself a welder to cut up and weld a pipe stand with  a tripod base, maybe?

If you have a suspended ceiling  or would be easy.In my old basement man cave I just put the close to the ceiling...it was great ,no problems. 

Just get a Boom Box save your money!!

bad idea ... try a pair of the Martin Logan ceiling speakers on closeout from audio Advisor ... send em back if you do not like them ... of course you will have some holes to patch though :)

there are speakers out there designed for in wall that have enclosures behind them. again, baffle step in the crossover is the biggest issue i see.

I guess I'm going with the general concept that speakers, in general, sound better when they are in a real boxed enclosure - like a dedicated speaker box - as opposed to just being a ceiling speakers with no box enclosure. I definietly have room to try to fit a real speaker with cabinet. It will point downward, just like a true ceiling mount speaker - but maybe the depth and richness of sound will be better sith the speaker in a cabinet pointing down as opposed to a true ceiling speaker?

Bad idea. Regular speakers are designed to point at the listening position. Mounting them flush with the ceiling will point them downward. They won't sound right.

crazy idea

if the in ceiling speaker has a crossover it was designed for in wall. a typical bookshelf will not so there is probably too much baffle step designed into the crossover for it to sound right.

You can do anything you want,it's your stuff!!Sounds like a lot of trouble to me though.
