Mystery Large Format Monitors

[Mr. Widget]

That looks absolutely repairable... and I agree with you, enlist the help of a professional. It is always more work to "unfix" a poorly executed repair.

What would you like to know?

Hello michaelg!
first of all - maximum details about acoustic filter ring. how it made and what linear displacement possible with similar construction. I'm planning custom IB woofers, more than 18", relative lightweight cone, probably double spider............
spiders seems like conventional. is it so?

all I found is http://www.annuarioaudio.it/proveT_files/5%20diff.pdf p.4

all I found is http://www.annuarioaudio.it/proveT_files/5%20diff.pdf p.4:
it.:
"in luogo della sospensione esterna, ed allo scopo di irrigidire il bordo esterno del cono, e tuttavia presente uno spesso cerchio di polistirolo espanso, che si estende anche alla parte posteriore interna, che aggiunge una trascurabile massa a quella dell'equipaggio mobile, pur assolvendo benissimo alla sua funzione di rinforzo.
nutriamo qualche dubbio circa l'entita delle perdita d'artia eventualmente attraverso lo spazio libero tra questo bordo ed il cestello del woofer stesso...."
eng.:
"instead of external suspension, and in order to stiffen the outer edge of the cone, and yet this is often a ring of expanded polystyrene, which also extends inside to the back, which adds a negligible mass to that of the mobile, while completing well its function as a reinforcement.
have some doubts about the degree of loss of limbs through the space between this board and the basket of the woofer itself ...."

how it made and what linear displacement possible with similar construction.

The SLE series uses a double spider.

I have some data but the file is too big to upload here.

PM me with your email and I will send it to you.

For your interest .... this is an iPhone photo of an old exhibit 28x22" poster from 1981.It was a blow up of an ad which ran in Studio Sound, Mix Magazine, etc.

BTW, yesterday, 8 December, was the 32nd anniversary of the launch of our Laboratory Series monitors, the first Fostex product ever introduced to the North American market.

Michael, thanks for that information and advertisement. Do you know of anyone who has diaphragms for the rounded slot tweeter? I need at least a couple.

Send your coordinates and requirements to me at [email protected]

We are considering reissuing these legacy monitors (in addition to new full-space variations with optional internal room correction and amplification) and would have new service inventory available.

In the meanwhile, I do have some very limited NOS diaphragms now and *may* be able to help immediately.

We are also attempting to build a database of former clients. To that end, please indicate which monitors you have and the name of the facility, if applicable. Install photos would also be very nice!

If anyone on these fora has an interest in new product, pre-orders or even parts, please contact me directly at the referenced email address.

Those monitors look superb and have the exact layout I have always preached. Modular. One big box for bass, and mids horn on top. What is the model for the monitors in the bottom of that picture? It seems narrower than the previous 4-way Fostex monitor. http://audioheritage.org/vbulletin/a...1&d=1194120962

Thank you. Our thoughts exactly!

If you are referring to the system shown on the bottom of the page of the referenced attachment, there is no model number - it is a system put together by an DIY.

BTW, if you are going to be at the Montreal Audio show in March, you may actually have an opportunity to hear our system.
