FOSTEX FF165K DRIVER

But in my TQWT they sound excellent. Taken alone, it rolls off a bit much for my taste. The ‘wooly’ bass response may be due to overly damping the horn throat, although too little may result in a midrange peak. 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. Stock, it lacks some treble but this is easily improved upon. The FE series uses ‘whizzer’ cones to good effect and the FF series uses an aluminum center.

Hi Jay Sounds like my experience. Really looking forward to some big time fun.

6moons audio reviews: First Watt – An introduction by Nelson Pass

I can’t figure out what the F1f65k Sigmas are doing but they look cool. 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 got the FEE in the mail late in the week. Audio Asylum Thread Printer Get a view of an entire thread on one page. 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. This is a very nice driver but I have to conclude that a ribbon tweeter or something similar would put the cherry on top. 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.

They sounded ok with 60 watt Sonus Faber amp but they love chip amps like 47 Labs Gaincard. We hope to see you at VSAC, since we have something [cool] to show you. Magnetically shielded, they also make great computer speakers. Posted by zobsky yahoo.

You’ll notice here that the response curves are extremely similar. I’ve never seen a real curve of the LE 8 and I don’t remember that much about their top end.

I hooked up a 4 ohm SS amp and they were Fostfx, but with a amp with 8 ohm output, they were lively and nice. They are amazing drivers for the money. I have not tried or heard the E or E sigma.

Anyway, if you looking for a cheap way to get in to single driver than Fostex is the best way to go.

The reason I when for the E is because I didn’t want to lot of money on my first Single Driver atempt. I made all my reservations this weekend. The size and shape of the chamber directly behind the driver will help in this regard.

The FE series uses ‘whizzer’ cones to good effect and the FF series uses an aluminum center. I popped one of them in one of my cabs to do an A-B. However, it does have a more “wooly” and less tight bass.

Hope this helps, Marco. The FEE has maybe just a tad less bass but the FFK has ff165j broken in for some time now and has also had some damping material wrapped around its ribs to absorb nasty reflections. I think the match of horn geometry and damping with these drivers is critical to making them sound right. This one, however, needs some kind of tweeter and while I think the real maximum excursion is bigger than the spec, I ff16k treat it gently with the “Jurassic Park” sound track.

The 4KHz peak of the uncorrected driver is easily taken care off and it’s pretty inoffensive.

Taken alone, it rolls off a bit much for my taste. It excels at one very difficult thing – to still sound good after the honeymoon is over. 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. 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 like the Jordan so much I stuck it in here anyway as a fine counter example.
