which kind of small speaker is best?

[magicmouse]

I am building a speakerphone kind of thing, to take my Motorola Droid and turn it into a deskphone. So i want to include a speaker in my project, and figured 3-4 inches is likely to be the max. Given that this is mostly for voice reproduction, I need good base response. What kind of speaker is best for this application? I see a lot of cheap paper cone stuff around but paper cones get brittle and wear out after a while, what kind of speaker would sound good, not be too expensive (no exotics please)??

thanks

lots of good 3-4" speakers. This one for instance Aurasound NS3-193-4A1 3" Extended Range, Black Cone, * 4 ohm *, in silver, black, 8 or 4 ohm
