Fostex F200A vs Visaton B200
 
I intend to make a pair of reflex speakers using a full-range driver, and have identified the Fostex F200A and Visaton B200 as likely candidates. I would be interested in views on these drivers, and which is best.

Domestic considerations limit the box size to 920mm high, 230mm wide and 300mm deep. Allowing for an 18mm wall thickness, gives an internal volume of about 45 litres.

You'd have to go aperiodic for the Visaton with a restricted volume, though you might just about get away with a reflex with much fiddling. If you really want reflex, then I suspect you'd have a better chance of achieving something decent with the F200a.

Well, you have the solo50 which fits your size requirements.
Check out Visaton.de web page.
Good luck!

I would think the Visaton is no match to the Fostex F200A, which is quite expencive.... but I would use a tweeter .... and I might ad a woofer as a 2.5 way, but thats a different thing

If he does that I wish him luck too. Look at the circuit they've slapped on it! What the Solo 100 & Solo 50 are, are heavily damped double bass reflex enclosures. This I just have to model. I'll have a crack a bit later, but I'm deeply dubious.

Fore Visaton B200 a big closed box of 200-250 liter could be interesting.... but its way above VAS and will take driver below its Fs and have high system Q, so I dont know ....Scott might comment on that ?

Hi Scott!
I've been curious about these Solo 50 and 100 before but know that you and others here at the forum are probably over whelmed by questions already.

Cheers!
Peter

They aren't anything special -just a heavily damped double bass reflex, a bit like the cabinet Fostex have on their site for the FE207E. No time to model them tonight, but I'll have a look in the morning. Heck of a complicated circuit they've put on them too. Personally, I'd build something like a 70 litre aperiodic cabinet for them, or stick them on an open baffle, which is what they were really designed for.

from having read about the f200a and vistaion b200,

I would recommend the fostex unit. expect an better all around driver.

the alnico is beastly too....if only for that reason, go with the alnico.

expect a different sonic aesthetic than the banana plant fibre stuff. a perceptible flat response should come from these. along with very high speed. the bump at 5k I would consider to be fairly negligible considering the flatness in the rest of the spectrum. what looks like just a dinky foam surround I am pretty sure is rubber impregnated, at least it was on the fx120 that I played with for a while.

the fx120 is a nice driver, would be a goood studio monitor. the f200a should be totally killer.

but I have heard neither.

only about them.

In an open baffle "shoot-out" (..notice the placement):
