Re: outta phase? if a tweeter is out will make sub...
A Tweeter being out of phase should not have any effect on the sub.
If one tweeter is out of phase with the other there will still be sound in the room as due to the high frequency the unequal time to your ear will mean you won't get perfect destructive interference and the signals won't cancel. Also the two tweeter signals convey much less information in common than a subwoofer or bass speaker.

Because the system is bi-amplified, it is important to replace the wires correctly to avoid phase problems. I don't know how the wires are colour coded, but if it is any help I downloaded the schematic and the wires are numbered 1: Woofer Active 2: Woofer Earth
3: Tweeter Earth and 4: Tweeter Active. Sorry if that's no help. Otherwise it should be easy to trace the wires to see which connect to earth.
Normally Speaker and Amp side will mark correctly the polarity. If wrongly connect phase may get wrong. If you understand or may know the different by hearing, if both tweeter phase is wrongly connect, what need to do is reverse the connection of one side the phase will change. you can try which give you the best listening feeling.
Possible this is a distortion from the Amplifier if the speakers are not damaged. however it is important to switch the speakers to confirm if the fault is relative to the particular channel in which case the amplifier is faulty. If not the speaker can be the culprit. All what is needed is to reduce the BASS level a bit lower when the volume is increased so as to allow the cross over to work. Also if teh cross- over network is faulty within the speaker the bass can vibrate on the tweeter.
Since there is no single crossover for two speakers it is likely both speakers experienced the same audio trauma and blew together. Something like microphone feedback will take thenm out in a literal heartbeat.
The 301's sometimes have an element in series with the tweeters that looks like a little light bulb (or it could be a fuse, too) and it is designed to blow before the tweeters die. They're easy to find if you remove the woofer to get some maneuvering space inside. If they'rethere and blown (visible) you can either wire aroundthem and be careful in the future or get some more.
Do a web search for "tweeter protection fuse".
If the tweeters did take the hit get on eBay and find some more, plus think about installing protectors if you can't avoid excessive distortion or power going to them.
Regarding pwoer vs distortion, the latter will kill tweeters in a blink so don't think a modest amp is safer than a powerful one. The modest amp will distort sooner.
hi, Do one thing set the control behind the sub. set the level and cutoff control at it half position. Set phase control at "0" position. Then test the sound. if you ate using tower speaker as front speaker then you have to set the position of phase control 180 , ok
There is a polyswitch in series with the tweeter. when it gets hot from lots of current running through it, it goes high resistance, attenuating current to the tweeter. Remove and bypass the polyswitch if this annoys you, but then you risk blowing the tweeter if you run it too loud!
he phase control will help the sound waves from your sub get synced up with those coming from your main speakers. If they arrive out of phase, there's the tiniest delay between **** Jagger's voice and Bill Wyman's bass, for instance.
An easy, accurate way of setting the phase control is to reverse the connections on your main speakers (the black wire goes to the red terminal and the red wire to the black terminal). Now play a simple selection, like a jazz instrumental with a good walking bass line, on your system while you're sitting in your listening position. Have a friend dial the phase control on the sub until you hear the least amount of bass. Leave the setting there. Returning your speaker wires to their proper places will now allow you to hear the most bass from your sub.
