High Excursion 8 Inch Woofer. Is Their Such A Beast?

[OMNIFEX]

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.

Try this, Steve says 4.9mm xmax

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.

Have you had a look at these ?

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.
