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. Hope this helps, Ff165i. 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 like the Jordan so much I stuck fkstex in here anyway as a fine counter example. Well, not the same as what you have in mind.

Of course, this could be dependent on a less-than-optimal match with the backhorn, but I suspect rf165k also has to do with the driver’s higher Qts. Stock, it lacks some treble but this is easily improved upon. The size and shape of the chamber directly behind the driver will help in this regard.

Anyway, if you looking for a cheap way to get in to single df165k than Fostex is the best way to go. I popped one of them in one of my cabs to do an A-B. I notice that Fostex seems to have three approaches for getting full-range performance in the treble. We hope to see you at VSAC, since we have something [cool] to show you.

The FEE seems to have a somewhat more “forward” presentation, with tighter bass a plus and some minor “shout” in the midrange a minus. Posted by zobsky yahoo. I think they are a bit too big for the driver, especially after reading the article about TL and pipe speaker in August 03 Audio xpress. I made all my reservations this weekend. But very thing turn out great!

Hi Jay Sounds like my experience. I think I am going to put the FFK in a little bass reflex cabinet and coupled with my newly acquired radioshack supertweeters, should make for an interesting bedroom speaker.

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. You’ll notice here that the response curves are extremely similar.

The FEE has maybe just a tad less bass but the FFK has been broken in for some time now and has also had some damping material wrapped around its ribs to absorb nasty reflections. The 4KHz peak of the uncorrected driver is easily taken care off and it’s pretty inoffensive. I have not tried or heard the E or E sigma. Really looking forward to some big time fun.

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. They work well in my 8. The FE series uses ‘whizzer’ cones to good effect and gf165k FF series uses an aluminum center.

Anyway, but after fine tuning with stuffing inside and around the whizzer cone and placement the result is stunning and no kidding here. See you there, Jay.

However, it does have a more “wooly” and less tight bass.

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. I’ve never seen a real curve of the LE 8 and I don’t remember that much about their top end.

Taken alone, it rolls off a bit much for my taste. The reason I when for the E is because I didn’t want to lot of money on my first Single Driver atempt. These drivers love DHTriodes. 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.

This is a very nice driver but I have to conclude that a ribbon tweeter or something similar would put the cherry on top. The difference is quite startling. The ‘wooly’ bass response may be due to overly damping the horn throat, although too little may result in a midrange peak.

But in my TQWT they sound excellent. They are amazing drivers for the money. The other horn cabinet was running my FFK which has been broken in for a month, It excels at one very difficult thing – to still sound good after the honeymoon is over.

They sounded ok with 60 watt Foetex Faber amp but they love chip amps like 47 Labs Gaincard. Magnetically shielded, they also make great computer speakers. Audio Asylum Thread Printer Get a view of an entire thread on one page. I can’t figure out what the FE Sigmas are doing but they look cool.
