Hi-Res AL-III internal photos (beware big files)

Thought you might like these photos. This is the standard AL-III+ woofer and crossover. I had a rattle in this woofer so I pulled it to check it out. Reinstalled it tight and voila! No more rattle.

When I first got my AL III's I thought that the rattle I had was in the ribbon but it is in the sub. I have not gotten around yet to doing this.

Cool pic's.

Heres the deal , I have AL-III,s also . My subs rattled , replaced them and still heard the rattle . What I found is the screws that hold the bottom plate need to be resealed . Any air that can escape from the sub enclosure will make a rattle sound........My original subs are back in now ....

That is NOT the same woofer they used on the AL-III standard. I'm wondering if they changed the woofer between the models or if your woofers were replaced at some point. Are you the original owner?

I am not the original owner. I bought them from Craigslist. The man I bought them from said he drove from Buffalo to New Jersey to pick them up from a store that was closing. They are not AL-III they are AL-III Plus. The crosssover is non-adjustable.

I think the real problem is that the screw holes are stripped. Look at the bottom of the enclosure where the sub is removed. Some of the holes are even cracked. Cheap MDF that these are made of is rotten stuff for holding wood screws. I think I am going to replace the wood screws with t-nuts mounted in drilled-through holes and machine screws. Eventually the movement of the sub will loosen these screws.

Use wooden toothpicks when you reinstall. Put them in the screw holes.

Put a dab of silicon , reseal......It drove me nuts until I discovered the problem . My where not striped . But I did notice they came sealed from the factory .

That is exactly what I had to do, Roy.

Also, I'm certain that isn't the original woofer from the factory. They are completely different, so it appears the previous owner replaced the woofers....

Thanks for the responses gentlemen. Does anyone have a shot of the original woofers? The magnet in my picture looks pretty large, typical of a high-wattage type driver, but the basket is the cheap stamped kind. I'm not sure of the manufacturer. Carver didn't make his own woofers, right? I think there is another thread on this I will look for it.

Yes, those wooofers were special built to Bob specs

I've looked all over but can't find any pics of the original woofers. Jimmy Neutron used to have pics on his site, but it's not longer up. I sent him a PM to see why...

Both pairs of ALIII woofs I have look like this.

Thanks a lot, mine definitely don't look like that, Jim. Wonder what I actually have...

Well, either Carver changed between the AL-III and the AL-III Plus, or yours have been replaced.

James, what do your AL-III plus speakers look like? You can remove the crossover & get a peek a lot easier than removing the bottom of the speaker...
