Looking to replace some foam rot 8 inch woofers with
high excursion 8 inch woofers.
The cabinets are;
19 inches tall
10.5 inches wide
7.5 inches deep
Power is not an issue, for I can feed them anywhere from
100 to 400 watts continuous per channel
Any suggestions and/or recomendations would be greatly
appreciated.

This might be a guide.
The trick is in finding one.

Peerless 8" HDS woofers have 5.5mm of Xmxax, thats quite close to high excurtion as an 8" is going to get, i also think that the adire AV8 has a reasonable xmax and it also models very nicely, something i personally am a bit causious of.
I've found a few...
There's the ApexJr Super 8 mentioned above...
There's the Adire AV8 mentioed above...
There's a Tang Band one that graphs really good for real cheap, of which, as mentioned above, can be a little skeptical.
Also, you could check out JL Audio 8W0, or 8W4 etc. I know they're good.
I believe the cheapest are probably the Tang Band and the ApexJr. Hard to judge how good they are without trying them.

Someone like John at Stryke Audio needs to start carrying the high-excursion 8" that TC-Sounds builds.
Cannon sound, in OZ have the 12" version on sale, I wish i could justify buying a pair or two.
They might be just the thing for a dipole sub

That PAudio TM-8 certainly looks like a great 8" woofer.
A mail order house in America sells the 10" and 12" version of it. The 12 inch is $420 and the 10 inch is $390. I think we see a pricing trend here....

Very cheap, and quite high excursion is the TB W8-740c, found at www.nuera-acoustic.ca.
Inexpensive, and they ship out of both the US and Canada, so shipping isn't bad at all.
Their listed 12mm xmax is right on the money, being measured by the (vc height - airgap height) /2 method. Very good power handling, despite their low rating in the datasheet. I've personally pushed 200W RMS (brownish noise) through one for an hour or so with no ill effects.
I'd like to see a little better suspension travel out of them to go with the 12mm one-way xmag, but it's about as good as can be expected within the confines of a small 8" diameter basket and a smallish diameter spider. I'd estimate it at about 16mm or so. At any rate, an excellent performer for its size.

There is the Eclipse 87081.4 with a huge excursion.
Here is the home page to download the pdf specs:
http://www.eclipse-web.com/products/speaker/87001dvc/87081_4.html
Seems to be selling reasonably cheaply on Ebay:
http://search.ebay.com/search/searc...=&ebaytag1code=0&st=&SortProperty=MetaEndSort
Does not mention symmetrical magnetic system-though I think it probably has one. Does not mantion SPL-some of these extremely long throw designs can have really low SPL's.

No mention of a symmetric magnetic field. That is usually done with either an extended pole piece or a shorting, (Faraday), ring.
Normally, I would think an 8 inch for $29 would not have a symmetric system-but then you would not think an 8 inch for $29 would have 12 mm Xmax with either. Tangband seems to have a lot of features you would not normally expect.
Thingyness, have you put these into a vented box, then run a frequency test to see how the woofer behaves near resonance? A woofer can perform fine in a closed box, but shear off half the waveform near resonance in a ported box.
I would strongly recommend a symmetrical field for anyone using a woofer in a vented box.
Omnifex-are these enclosures vented or sealed?
Peerless 8" XLS
Peerless have a 830491 which is a 8" XLS with an Xmax of over 10mm based on the 8" HDS and is available in Australia from WES Components: http://www.wescomponents.com/

Thanks Everyone!
So far, the ones that work best in this enclosure are;
TC2 8 (-3db 28.19Hz) www.tcsounds.com
TB W8 740 C (-3dB 35.79Hz)
I'll post the graph later...................
P.S. Its a Reflex cabinet

What are these speakers, 2 way? 3 way? Very high excusion woofers, even 8" ones, are usually more designed for subwoofer applications, and likely wouldnt have as good of upper bass, lower midrange characteristics, IF they would need to do this in youre system
That's fine.
They will be used for frequencies 70 - 25Hz. I have another
set of speakers I can use for mains, and, these will be turned
into subs.
This is for my mom's video system, so, she perfers to keep
her original cabinets.
I figure I'll give her my old Soundcraftsmen 7502 lying in
the corner for the bass, and, use a Sansui AU X 77 for
the mains...............
Got an old DOD crossover that will fit in nicely.

Where are you from by the way? I pride myself on having a higher knowlege of geography than a typical american (not very hard!), but can't place youre flag
well, sounds like you've found youre driver. One thing I'd say, the tc2 has a listed xmax of over 16mm, I'm sure that is two way, which would bring its one way xmax to over 8mm, still very very high for an 8" driver.
