FE108EZ and FE168EZ

[LilMik]

hello all,

i heard an read a lot of good things about the 108EZ and the 168EZ. has anyone ever heard one of them and did not like the sound at all? if so, why?

and what is the diffrence, soundwise, between the 108EZ and the 168EZ. is the resolution, the soundstage and the holograpic presentation of the 168EZ as good as it is with the 108EZ.

thx

Hi,

I have designed a horn for 168EZ and it will be on my web page soon.

The 168 pretty much offers everything the 108 does but with more grunt in the lpower registers. Mounted in a BIB it's lethal.

Onur -that another double horn design or a single one?

I just designed a back loaded horn enclosure trying to stay in reasonable dimensions. Height is about 1.4 meters and the width is 70 cm and the depth is 60 cm. This is an exponential horn with a length of 1.7 meters and a rear chamber of 16 liters. Yes, yes I know, it is not a horn. I heard it a hundred times before. With a rear chamber that big, it doesn't qualify as horn. Who cares as far as it sounds nice

Again, the design will be on my web page after a couple of listeners comment on it first.

HI

I have made a "Cornu" horn, with FE168EZ. They sound very good look here -> www.micro-io.dk

Best regards

Nonsense. It's as much a horn as any other domestic horn design is. If it's got a long, expanding vent, then it's a horn. Ironically enough, GM decided to blow away the remnants of my misunderstandings earlier on today, and gently pointed out that all expanding lines are technically horns. Doesn't matter what they are coupled to, or even if they are not coupled to anything (i.e the TQWT) -they're horns. Period.

I like that definition. Solves many problems. Rather inverts much of my previous fooling around, but it's perfectly logical.

Here's the one I've been working on with Dave (P10) which is also a big vent reflex type. Spawn of Frugel-Horn The primer on the prototype enclosures is drying as I type this. In my case I use MathCad rather than AJ horn, but we've clearly got simlar objectives in mind. I really like these BVR types over the smaller chamber, longer path length varieties -I can almost always get a smoother response (with just as much efficiency) this way as the more usual QW types. Goodness knows why the horn mafia get so worked up about them -they've been around just as long. And as you so rightly say, who cares what the method is, so long as it sounds good!

hello,

i know the 103e in the recommended horn-type enclosure and the 166e in the recommended horn-type enclosure, and to my ears, the 103e does the "disappearing-act" better then the 166e. of course that's an advantage. can the 108ez also disappear better than the 168ez.

also i am a little bit concerned about the 7khz peak you can see in the 168ez frequenze response: http://www.fostexinternational.com/d...df/fe168ez.pdf ... could it be that the 168es does sound very bright? the peak look's really nasty i think.

I haven't heard a problem in this respect with the pairs I've heard. And believe me, I don't like bright speakers -quite the reverese. Bright systems just give me a headache. Mind you, the peaks in the 168 are out of our ear's highest sensitivity region. The 108 has the edge in the disappearing act business (not in the Fostex cabinets though, neither of which are very good IMO) but the 168 counters with superior bass extension, dynamics and SPL capability.

Hello Scottmoose,

thank you for your comments. They are very helpfull.

That's good to hear :-).

So you don't like the Recoemmended Enclosures? Alternatively i could build the Frugel for the 108ES, Ron's Horn or the "Spawn of Frugel" (my favourite, though it is still in progress i think), but i have not found any other desing for the 168es but the recommended. I am not sure if i could build Nagaokas D-37 or the D-168 you can see here http://www.maclementhorn.it/Fostex_Progetti_Japan.htm ...... because, as far as i know, they were both designed for the 168ES2, not for the standard 168es with the little magnet.

i can't wait to see your project, hopefully with some measurements :-D.

the spiral horn looks cool, i think. it's a pitty you can't see the spiral anymore once the box is closed. but a spiral horn is, if you wnat to use wood, really hard to build. also, personally i do not want to hang the speakers on the wall.

can you tell me more about the sound of your spiral horn compared to a conventional horn-type speaker like fostex recos?
