absolute 2's...blown tweeters

[barryhercules]

i managed to repair the tweeters on my absolute 2's by taking off the cones and unwrapping the broken copper wire to re-attach it to the terminals.... i dont know a lot about electronics but i imagine this will have an effect (albeit subtle) on the sound.... i know the number of coils effects voltage. the fuckers are working now anyway


any of you lot know more about this? i'm imaging it may make the tweeters lower in volume than they were originally..... am i right? will it be noticeable enough to be arsed?

any electronics/ engineering heads out there?

can you be a bit more detailed with regards to what was wrong with them in the first place and what you did to fix them??

i cant get my head round what you mean... sorry...

[barryhercules]

they'd been used at a party and driven too hard too long.... the copper wire thats coiled around the inside of the cone (between the magnets) had snapped away from the terminals........ so i unwound it a couple of turns so i could re-attach it. they work.... just wondered what effect that it would have on output

[mosfret]

i'm not familiar with the speaker in question so i'll give you a bit of a generalised info.... hope its neither too patronising or geeky...

the voice coil of a loudspeaker exhibits both dc resistance, (what you can measure with a ohm-meter), and inductance. the impedance, (ac resistance), of an inductor is frequency dependant, as frequency rises so does the impedance.

if you halve the number of turns on a coil, you halve the resistance and inductance, with less resistance more power will be dissipated in the load. in your case this would have the effect of making your tweeters louder. as you've probably only unwound a small percentage of the total number of turns of the coil this will probably have very little overall effect.

if your monitors are not bi-wired, ie, they have a passive crossover, the change in the overall impedance/inductance of your tweeters may shift the frequency at which the signal you feed into the box, is split between the woofer and tweeter.

if they now work and they sound alright, then theres no real problem!!

the only thing id suggest, if possible, is to put a meter on the terminals of the box and make sure the dc resistance is as expected... if the overall impedance of your box became too low, you could damage your amp....

if you want me to re-phrase anything/try to explain things better, let me know...

hope this helps...

no not patronising at all mate, thats just what i was looking for. nice detailed answer... cheers mate!

thanks for taking the time

take it easy
