I’ve never seen a real curve of the LE ff165i and I don’t remember that much about their top end. They sounded ok with 60 watt Sonus Faber amp but they love chip amps like 47 Labs Gaincard. It has 96dB sensitivity and if you bring in a good tweeter, maybe a nice ribbon ff165m 5K, I think you’ll really have something. They work well in my 8. I was going to go with the 8″ Fostex but I don’t want bigger box and the 6.

We hope to see you at VSAC, foxtex we have something [cool] to show you. The reason I when for the E is because I didn’t want to lot of money on my first Single Driver atempt. Magnetically shielded, they also make great computer speakers. This is a very nice driver but I have to conclude that a ribbon tweeter or something similar would put the cherry on top.
Posted by zobsky yahoo. Of course, this could be dependent on a less-than-optimal match with the backhorn, but I suspect it also has to do with the driver’s higher Qts. The FE dostex uses ‘whizzer’ cones to good effect and the FF series uses an aluminum center.
Well, not the same as what you have in mind. Taken alone, it rolls off a bit much for my taste. Really looking forward to some big time fun. I think the match of horn geometry and damping with these drivers is critical to making them sound right. I have not tried or fodtex the E or E sigma. I think I am going to put the FFK in a little bass reflex cabinet vf165k coupled with my newly acquired radioshack supertweeters, should make for an interesting bedroom speaker.
I like the Jordan so much I stuck it in here anyway as a fine counter example. As pointed fosted 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.
Wanted – Fostex FFk Drivers
But in my TQWT they sound excellent. See you there, Jay. The size and shape of the chamber directly behind the driver will help in this regard.
These drivers love DHTriodes. But very thing turn out great! The FEE seems to have a somewhat more “forward” presentation, with tighter bass a plus and some minor “shout” in the midrange a minus. It excels at one very difficult thing – to still sound good after the honeymoon is over. You’ll notice here that the response curves are extremely similar. Hope this helps, Marco. Stock, it lacks some treble but this is easily improved upon.
However, it does have a more “wooly” and less tight bass. In any case, the FFK has 94dB sensitivity, works well as a full-range driver, betters its bigger brother in the treble but of course is not as good in the bass.
The 4KHz peak of the uncorrected driver is easily taken care off and it’s pretty inoffensive. I can’t figure out what the FE Sigmas are doing but they look cool. 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.
I have also noticed that these drivers are very sensitive to impedence match of the amp, and possibly the kind of amp as well.
