Speaker act more like tweeter only, not mid range + tweeter
These speakers (Yamah NS-A327) were sold to me as being stereo speakers covering mid range and tweeter function and should be used in conjunction with a subwoofer. They act more like tweeters only and, when checking the resistance of the voice coil it looks like there is a capacitor in series with the voice coil. Can anyone tell me what these speakers are really supposed to be - or provide the Yamaha specifications for them?

It's a big job, but the results are great. Bi amp-ing is where the tweeters and mid range speakers are separated and connected to separate amplifiers. You'll need to have the correct gear before messing inside your speakers. You'll need to have another amplifier. Not knowing what amp you have now, getting a stereo signal into the second amp may be a problem since you'll need a line level signal into the second amp. An external crossover is best. Technically, you could use the ones in the speakers, since you'll be removing them anyway. Now for the speaker mods: On the panel where the posts for the speaker wires are you'll need to install another set of binding posts. We're assuming you have separate subs. Open the speakers and remove the cross over. The wires from the original posts should now connect to the mid range speaker. Add wires from the second set of posts and wire it to the tweeters. Now connect the output of the amp to the removed cross over and wire the mid range out on the cross over to the posts that connect to the mid range speaker. Do the same for the tweeters.If you have three way speakers, you'll have to run a 3rd set of wires from the crossover to the woofers in the cabinet using another set of binding posts. Controlling the volume on the second amp will be difficult since you'll have to adjust it manually. Remote control volume level will be lost on the second amp.
check the tweeter and mid range. its coil may become faulty.
for checking the speakers carefully remove the speakers one by one, remove its connections.
and check the speakers with a AAA cell. is it producingcracking sound. if not the speakers coils are burned.
Remove the speaker wire from your amplifier. Using a 1.5v battery place the wire on both ends of the battery. Observe if you can hear a cracking sound on the tweeter and the mid-range. If there is no sound., your speaker is busted and needs to be rewind or replaced.

Exactly the same way, you would for a normal speaker. Four-ways combine a woofer, a mid-range, a tweeter, and a "super tweeter" into one speaker. But it should still only have one positive and one negative.
you should be able to remove the passive in-line crossover, but since it is blocking everything below 3500 hz, there is no need. leaving the passive crossover in place will also help protect the tweeters if something fails in your setup as any amped frequency below 3500 can seriously damage them.
