None of the current gen FE have banana pulp cones.

I had one guy tell me why would you spend $50.00 on a fostex when you can get this brand over here with better frames and magnets and phase plugs and so on?
None of the $50 Fostex are big enuff for a whizzer cone (something that if possible should be avoided). And usually if there is no whizzer a phase plug not needed. Nothing wrong with the Fostex magnets or frames.

They definitely benefit from a work over.

This person will not even use a fostex
I can relate. I personally prefer the smaller drivers. And i don't ever live with them stock. The FF85wKeN is one of my favorite 3 drivers.

Well dave you could e-mail me and I could tell you some thoughts I have
Feel free. My email is on any of my sites. I can mail you back some of the comments from some of my clients.

P.s. I forgot the F-120a driver the 5" inch fullrange $252.14 each?
It is a 4 1/2" driver.

This driver is one of their higher-end drivers. It sports a whole lot of expensive Alnico. I feel it is up on the part of the vlue curve where you start paying a lot for small increments of improvement. The broadly similar FX120 is a much better value. Jeff can add comments about them. Before & after.

$50 seems reasonable for around a 4" driver nowadays (4.5").

$120 for the fx120 seems a stretch for a single 5" but people do like it.

$252 for the alnico fx120?
That seems a bit steep.

The fx120 seems to be a better driver than the ff125wk, but at more than double the cost (ouch).

I'm still not hearing the "issues" with 125s that some folks gripe about (rather like the previous 127FE) , and along with MA Alpair 7.3 they'd certainly be on my short list for simple single driver FR system
I am with Chris here, I heard them in their official "BK" cabinet in Japan and I liked the sound, it was not harsh to my ears. I even bought a pair then. I may buy the BK cabinets next time I am in Japan. The packaging and weight could still fit in my business class limit. I also liked the 105 which was very similar except for a slightly lighter bass, as expected. The 85 was obviously refined, but personally I would not use it without a sub, or in a FAST configuration - I want some bass in my music. I also liked the 165 and 225, but they will benefit from a tweeter.

Fostex drivers are expensive?
I partly agree with JDM. My big beef is the cheap stamped baskets. Tang Band units at the same price often "feel" a lot more expensive and luxurious.
It must be said however that the FFxx5WK series produces rather nice tones, in spite of their stamped baskets. The Fexx6En series has never been my favourite however.

It is a pity that they don't replace their sigma series with their limited editions. I heard 2 limited edition fostexes over time and they were remarkable, much better than the sigma series.

FWIW, the big gripe I'd have with the "limited editions", is the "limited" part, and the cost - who are they kidding, except for alnico magnetics, there's very material or labor wise to justify the cost of many of those, and they certainly don't always perform substantially better than standard models.

A few years back a buddy of mine had a pair of the FE206ESR in the fridge sized Fostex BLH design - except for a lack of top end that was easily enough remedied with the addition of bullet supertweeters (costing more than the FR btw), and some midrange colorations most notable on vocals that I'm convinced were due to the enclosure, they were quite impressive.

OTOH, one of the most fatiguing and unlistenable drivers I've heard in a long time was a special edition - FE138ESR. They made a decent enough (if not thrifty) mid-bass driver, but very hard to listen to full range.

No, you've got that wrong. The FF105WK is a better driver however I leave it to your own expertise to figure out why.

I clearly remember other trapezoid designs so it is not unique at all. And if you had a proper understanding modelling and the interactions with a room then you would discover that putting the port in the bottom as with the metronome has some some very large benefits.

Sure they have stamped baskets, but they are well engineered and well built. I have seen many cheap stamped basketsm these aren't them. In the end it is how they sound for the price, not how pretty they are from the backside.

People talk about Fostex having shout... these literally shrieked. I wouldn't go as far as saying they'd be good midbasses. They did really good bass thou (used in a FAST with FF85)

Not to sound like a broken record...but there was a lot of R&D in to this.

As far as the 120's, have a few of them, nice bass. The 125s are about 1/2 the and in this box, the bass is about the same.

The 125 have very nice midrange (and now bass). I don't know why more energy hasn't been spent on a simple filter.

I'm about ready to go ask that popular fellow on the multi-range page, he seems to well versed in XO design.

Price is also dependent on how many they make, where they make them, what their overhead for R&D is and so on. Very few companies don't have a middleman. Having worked in manufacturing, if you understood the entire chain, it would take your breath away. Look at my least favorite driver, the 125. I bet it left the factory at under $7 US. $57 at my door is not a lot of markup.

Go to the drug store and look at the cheapest calculator on the shelf. About $5. Now think in your mind all the parts, all the steps and all the middlemen it took to put that on the shelf. Darn near impossible.

My beef if they did not quite finish the engineering. They seemed to have used the same paper for all sizes, and that just won't work.
