al3 subs ?

are these the infinity 10.1 that are used to replace the oem type?

http://springfield.craigslist.org/ele/1682951808.html

looked around last night and I see....

DISCONTINUED.....

are there specs for the stock driver on this site?
and what might be the replacement for the 10.1?

thanks.....

That's them! Grab-em while you can..those are the dual voice coil models. Almost IMPOSSIBLE to find!

thanks,

but if I can not find them, any others I might look at?

In the past 3 years, that's the only OTHER pair of dual voice coils I've seen (I own the other pair)....they're especially difficult to come by. I have a permanent search set up on ebay for them.

well talked to the guy yesterday
asked him to just send the speakers, I dont need the box.
he is down for that.....

but as this is an outa state craigslist thing and 200.00 is a bunch to loose if things go badly...

going to deal with this on monday...
get the shipping costs.....

did find out why the one woofer was noisey, the spider separated from the voice coil, and was letting the coil move side to side, reglued this last night, and will see if it will hold.....
that means loud testing.....
the other one has the same issue, but they ran it to long that way and the coil rubs......
that explanes the blown fuse....

a big difference in size......
will test the oem woofer, if it tests okay, I don't need this....

now, as to hooking these up, should I hook up both coils and how, in series or parallel?

FYI: If you are going to replace one sub, you'll need to replace both. You DID get two Infinity subs, right?

There are several options here. First, I need to know exactly what we're working with for amplifiers & what preamp you'll be using.

First things first; you have THREE sets of Amazings?!? AL-IIIs, Plats, and Silvers???? WTF?!? (I'm jealous)


I asssume you'll be using the TG-1 you've previously mentioned. I read through threads and it looks like you have a PT-2400 and two TFM-45s, correct?

You could run the ribbons off the 2400 & run one 45 for each sub (one channel per voice coil), which would be WAY kickass!

Here's the common way to run off one amp; I don't recommend going the 2 ohm route for the sake of your amp, and the 8 ohm route will necessitate raising the gain on your amp to bring it up to the level of the ribbons. Another option would be to wire for parallel, but insert a 6 ohm resistor inline to raise your overall impedance to 4 ohms. It would be difficult finding a resistor that will take that kind of power, though....

yes I have 2 infinity's.

doing one would sound bad....

going to use the 2400 on the plats

and use the other 2 45's for the AL3, one amp doing the subs the other the ribbons.(one has a higher background noise level,HISS, this is the one I use to do subs with)

and the 3rd 45 that I am a tempting to fix will do the silvers......

the preamp I have is a CT 27v
but my eq has a good gain on ot if I need to add a bit more.
right now I drive 4 amps, 2 45's and 2 kenwoods.
and with the volume at 11:00 it is at a db reading of 105 A wieghted....
14 feet back when sitting in my man chair.....
got lots of gas left, so to speak

well since the subs I got are dual coil 4ohm, I thought why not drive each speakers coil with 1 channel from an amp, so I put in 2 more terminals and unhooked the sub crossover and gain control pot, as this will go thru a active crossover.
took a few picks of the crossover .......
came out okay, will finish the other speaker tomorrow
going to drive the ribbons wth a 45, and the subs with kenwood basic m2a amps (these have level controls on them), hopefully it will sound okay.....










































this is what happens when I get bored......

Wow. Bi-amped subs! Now that sounds cool. You could use a 400x7 to power a pair of Al-IIIs and a center! Gary?

You can do that with the dual voice coil models.

I suggested this in the post above~

Mine are the single voice coil models.

Holy Crap! This, I would like to hear!

SO, how do they sound?

nice...
the ribbons in these thing are nice and tight.
these were made in 95, so I would guess some of the last out the door.
the lady who owned them was the purchaser for carver,
said when they got down to 12 people left it was time to look for a new job.....
they used these as surround speakers, so my guess is these have low hours and were not drivven that hard, I think the woofer died due to the spider drying out,glue breaking away, and letting the V/C rub and smoke it self.
the bass level is way more than the oem thats for sure.....
I have the gains turned on the amps less than 1/2 up and it has a lot of punch......

the ribbons in these do look way different from the early ones, the alum strips are a lot flatter, less wrinkle if you will and they also have a small foam support in 3 places up the length of the ribbon, I would assume the back also.... kinda like a support to stop ribbon slap.

so on the silvers I have I did the hair dryer trick, this did help.
and I also used small felt strips about 3/8lgX1/2w 2 per spot, 3pl front and rear.
laid the speaker flat,
took a 10GA copper wire ground to a point to position them in place, then used silicone to stick them to the magnet,
then cut a strip of felt to cover the length of the ribbon down the back. used rubber cement, holds real good.

now I have no more ribbon slap on these ..........

I will add a 2nd set of binding posts to add a amp just for the woofers, not to sure about these rebuilt crossovers, just dont sound right down low...kinda muddy
and I think it lets too much low end to the ribbon,......
but all in all they sound okay, will play some more to make them sound great....
