Fostex Tweeters : T90A, T900A, T500A

[usa_satriani]

Hello.

I was wondering if there was a great difference between T90A, T900A and T500A ? Does it justify the cost ? The tweeter would be used over 13-14Khz

I have a FT96H, how would you compare it to the others ?

Thanks for your help.

Greg.

I have both the FT96H and the T90A, and prefer the T90A as
sounding warmer and more extended. The comparison is
like the (discontinued) Audax PR120 vs the PR130.

I cross them both up around 10KHz.

I have not played with the T900A and T500A.

Thanks for your reply.

Yeah I was pretty sure that the T90A was better than the FT96H, that's why I am going to put the FT96H on the FE168EZ which are my surround speakers and get new tweeters for the FE208EZ.

I am now wondering what could bring the T900A or the T500A. But I think it will be T90A or T900A.

Thanks.

PS : funny thing, I am making an Audax kit with a PR130 🙂

Comparison

Hy Guys,

Have you compared these fostex speaker Kit with a B&W or Triangle speaker?

Thanks,

Alexandre.

 

[usa_satriani]

For me there is no comparison, when I listen to B&W speakers I am quite bored and I find nothing natural. They seem to smooth all the edges.
I didn't listen to Triangle speakers for a long time.

Hi,

Which kind of music you can listen using these full range speakers ? You need also a subwoofer to work with these speakers ?

Thanks,

Alexandre.

 

[usa_satriani]

Hi,

I listen to a lot of kind of music but mostly rock and metal music.

Depending on what and how you listen to music, a subwoofer is quite recommended.

I have backhorn enclosures for my FE208EZ, you can listen to music without a subwoofer. But depending on how I feel and the music I am listening to I plug or not the bass speakers. Crossover frequency variying from 80 to 200Hz.

Greg.

Greg,

Do you have the recommended enclosures from Fostex for your 208EZs?
A friend of mine is planning to build them and he is wondering how they sound.
He allready has order a pair of 208EZ and a pair of T90A.
Do you use a different cap instead of 1uF that is reccomended for the T900A?Or the same?

I will ask him to come here on a french forum.

Greg has the Nagaoka enclosures which are one of the best backhorn for fostex drivers :

I think I need some rest.
I saw 10-31-2005 at Greg's last post and I thought that we have 2006!

Hey,

I do not use the recommended enclosure for FE208EZ which you can find on the fostexinternational website. I use the Nagaoka D58-ES enclosure, you can find the plans on my website (click the english flag) if you want : satriany.free.fr
I don't know if this case is better than the Fostex one as I didn't try the Fostex one. But it is working well and I am sure the Fostex one is OK too.

FE208EZ + T90A is a great choice !

I am now using a FT96H with a 1.5µF capacitor and a Fostex L-Pad.

I will try the T90A, I don't know if the T900 is worth the money, maybe someone can tell ?

I tried 1, 1.5 and 2 µF and I think the 1.5µF is the best : with 1µF the cut is too high and you are missing some details. Masao Ida used a T900A with 1.5µF too. With the L-Pad you can attenuate the tweeter the way you want.

Hey Lagroute--

Wow! These look really nice! Do you know how Greg painted these enclosures? Is that a stain or a paint? It looks like it was brushed on, is that right?

I have a really hard time getting MDF to look good, but this is clearly a wonderful job.

Please let me know, if you can!

Thanks!
Kofi

Does anyone know what the blazes that design at the bottom of this page is (the tall, skinny one, that appears to be labelled F2000)? Looks like it's using the FE168ESigma. And can anyone fathom out the plans for it, for that matter?

Its the Nessie jr, a smaller version of the Nessie which used an FE208ES or SS, I could look it up if you really wanted to know but they are both "unobtainum" anyway, the jr used a FE168ES IIRC. They are long pipes originally used in AV setups and from what I could understand did amazing bass, I suppose the roof loading helps.

Looks like the 168EZ to me. Here's the plans, I think:

Now about the finish on that MDF...

[Lagroute]

Hello,

The best way to discover the "how" of this finish is to ask Greg himself (he is usa_satriani) 😉

I think it's stain ...

Thanks for your comment 😉

I didn't know how to tell you about the finish so I asked a translator :
it is a mahogany tree varnish, I put two layers. On the edges you should put 3 layers because the MDF absorbs a lot there.

For the FE168EZ I chose the D37 plans which is the little sister of the D58-ES.
