How to deal with a drop ceiling that eats bass?

My experience is that you live with it, or better yet get rid of it! Drop ceilings do what Rives said, and are an EASY source for noise and rattles. They suck up highs and some mid, and bass goes right through them.
How high is the SOLID ceiling above? What's it made of?
One solution might be to add some REFLECTION to places on the drop ceiling, so it will ad more diffusion and reflection. However, this depends on what else is going on in your room. If you have a carpet and lots of absorbtion around the room, your drop ceiling is DEFINTELY not helping your DEAD ROOM sound. Rooms will vary.
Good luck

Sorry to rain on AUDIOKINESIS'S parade in regards to his info on "dirrectional bass". But that advice is about at WRONG AND TECHNICALLY INCORRECT as I've ever heard from an audio forum post! There is no technical, physical, or practical data available to support those statements!
Infact, I'd like to hear Rives's resonse to what Audiokinesis said about dipoles, dirrectional-bass from di-poles(?), and drop ceilings!
Rives???...
