[QUOTE="squeak9798, post: 1340005, member: 555320"] Depends. Running a tweeter full range will damage it relatively quickly if played at any kind of reasonable volume. Mids don't necessarily need to be lowpassed, but the resulting sound may not be too pleasant. And the inductance of the speaker will create a natural high-frequency roll-off of the frequency response. Mids don't necessarily need to be highpassed, but their mechanical power handling will be diminished and trying to play them at a loud volume may result in damage. Shielded tweeters have a "bucking magnet" (aka "shield"), which basically counteracts any stray magnet field emitted from the speaker's magnet, allowing it to be placed close to monitors, TV's, etc. If you place an unshielded speaker close to a TV or computer monitor, the speaker's magnetic field will screw up the picture. Adding a "shield" (basically a magnet out of polarity with the speaker's magnet) allows this to not be as much of a problem, since the two magnetic fields effectivley cancel each other out. [/QUOTE]
