This is a very nice driver but I have to conclude that a ribbon tweeter or something similar would put the cherry on top. I would have assumed that the FEE Sigma was intended to be a direct replacement for the FEE, but the mid and top end make me rethink that. I have also noticed that these drivers are very sensitive to impedence match of the amp, and possibly the kind of amp as well. Anyway, but after fine tuning with stuffing inside and around the whizzer cone and placement the result is stunning and no kidding here. Hi Jay Sounds like my experience.

Hi Jay Sounds like my experience.
I think the match of horn geometry and damping with these drivers ofstex critical to making them sound right. Well, not the same as what you have in mind. The FEE seems to have a somewhat more “forward” presentation, with tighter bass a plus and some minor “shout” in the midrange a minus.
Ff165m notice here that the response curves are extremely similar. This one, however, needs some kind of tweeter and while I think the real maximum excursion is bigger than the spec, I would treat it gently with the “Jurassic Park” sound track.
As pointed out before, it appears that the high-efficiency drivers make the most out of a current source and here we don’t see any particular advantage. I made all my reservations this weekend.
The 4KHz peak of the uncorrected driver is easily taken care off and it’s pretty inoffensive. But in my TQWT they sound excellent.
I was going to go with the 8″ Fostex but I don’t want bigger box and the 6. I hooked up a 4 ohm SS amp and they were DOA, but with a amp with 8 ohm output, they were lively and nice.
However, it does have a more “wooly” and less tight bass.
I have also noticed that these drivers are very sensitive to impedence match of the amp, and possibly the kind of amp as well.

Hope this helps, Marco. They work well in my 8.
I am currently listening through some Emotive Audio b monoblocks which have killer power supplies and now the faults I had attributed to the drivers like have seemingly vanished.
Magnetically shielded, they also make great computer speakers. It has 96dB sensitivity and if you bring in a good tweeter, maybe a nice ribbon above 5K, I think you’ll really have something. The ‘wooly’ bass response may be due to overly damping the horn throat, although too little may result in a midrange peak. Really looking forward to some big time fun. They are amazing drivers for the money. It excels at one very difficult thing – to still sound good after ff165 honeymoon is over.
Fostex FFK Full Range Speaker Woofer Loudspeaker
I notice that Fostex seems to have three approaches for getting full-range performance in the treble. I think they are a bit too big fc165k the driver, especially after reading the article about TL and pipe speaker in August 03 Audio xpress. Posted by zobsky yahoo.
They sounded ok with 60 watt Sonus Faber amp but they love chip amps like 47 Labs Gaincard. These drivers love DHTriodes. Anyway, if you looking for a cheap ff165, to get in to single driver than Fostex is the best way to go.
I popped one of them in one of my cabs to do an A-B. Audio Asylum Thread Printer Get a view of flstex entire thread on one page. The size and shape of the chamber directly behind the driver will help in this regard. The reason I when for the E fpstex because I didn’t want to lot of money on my first Single Driver atempt.
I’ve never seen a real curve of the LE 8 and I don’t remember that much about their top end.
