ALS- III Help

Ok folks I finally broke down a got a pair of ALS-III's today from a local seller (wife is still trying to force them up my pooper) however I was able to get them fairly cheep and with cheep comes issues. I have them connected to a pm 1.5 not bi-amped at this time and when I push them not real hard the amp stops just for a second or so and them kicks back in. the adjustments on the back when turned have static. Is there somewhere I can send the crossovers to check them out? any sugestions to get started.

Re: ALS- III Help

pull out the woofer fuse, and see if this stops the short that you are getting....
ask me how I know this.... :shock: :shock: :shock: :shock:
when my woofers surrounds blew out, my amp did this also....

you can pull off the back and spray cleaner into the pots, work the knobs back and forth....
I did this to mine also, and my infinity 150 pots, these scritched real bad, after a hit of contact cleaner no more noise, and they did sound a bit better.....

Re: ALS- III Help

I had thought there was a short when it happened and checked my wires to the speakers just in case I was in a hurry. Did you have to replace the woofers or get them repaired?

Re: ALS- III Help

those woofers are on my plats...
hey Toymaker, he wants to know if I fixed the surrounds yet????????? [-o< :-" :-" :-" :-"
still on the hunt

the woofers on my al3, 1 was toasted, coil was pulled apart and the wire sucked up into the space between the magnet and coil holder, spider was also ripped up, the other was just sent out... to some one who needed it, I replaced mine with infinity woofers,
you can find these on craigs list, car stuff.
kappa perfect 10.1 10"
lots of single VC, but the dual VC I found do show up time to time...

Move the woofers in gently with your fingers & feel for scraping or non-movement.

Good advice from mbskeam. Buy wome Caig DeOxit to clean the pots on the crossovers. FYI: the M1.5 is adequate for the AL-IIIs, but won't drive them hard with authority~

Re: ALS- III Help

While you're in cleaning the pots, you might also check to see if the crossovers look burnt in any areas.
It should sound like it isn't there!

Re: ALS- III Help

Ok guys here's what I've come up with so far.....It looks as if the cross overs are bad the subs play great when hooked directly to the amp with the same wattage that took out the amp when hooked to the cross overs. the ribbons do not have a single bad area and sound pretty good. I will be parting them out in the newbie section so that those that need parts will be able to repair or replace the parts that are needed. I know for a fact that these speakers have not been for a long time and have been collecting dust in the corner of a house. I assume he fried the cross overs and has not been playing them since,

Re: ALS- III Help

If you can determine that the ribbon part of the crossover is fine, what I would do is disable the bass part (i.e., go directly to the woofer with its set of binding posts), and leave the ribbon part of the crossover intact, because it does provide the needed equalization to smooth out the ribbon non-linearity caused by the channel in which it is mounted. You will, of course need an external two way crossover for optimum performance (to manage the crossover between the highs and lows gracefully). Just be sure to set it above the ribbon crossover's corner frequency (150Hz). Around 200Hz is where the ribbon really gets linear. Or, depending on your pre-amplifier, you could use the subwoofer output for the woofers. I know with the Sunfire TGP-IV, you can dial up the crossover frequency to around 200Hz. Then you wouldn't need an external crossover, but still need an amp for the woofers and one for the ribbons.

Re: ALS- III Help

The TG-IV will only crossover up to 160 hz, FYI.

That's probably just fine, as the original crossover point was 150Hz.
