Do you mean the mini-line? What Fonken enclosure? I can messure it, but its difficult to show the low frequencies (because of the room). I can't messure outside.

Here you see the enclosures:

It can take a few days or weeks until I can make measurements.

Or a link to some measurements would be fine as well, I can't seem to find the enclosure anywhere besides bpa.

Also I'm not quite sure about the tang-band. At the moment I'm using a pair of monacor spx-32m which are really great in detail compared to my previous speakers. So the next pair should be "very good" speakers. I don't have the budget for "amazing" but I'd be willing to spend around 80€ per driver.

cheers,
hurtz

I've moved away from Tang Band and much prefer the new Fostex series based on having the FF125WK and the FE166En. (and had the Tang Band W4-1320SJ (IIRC) - the 4" bamboo).

Perhaps if you can accomodate a small desktop sized horn you might want to look at a ported back loaded horn - I only came across this in the last few days on youtube and it looks interesting - no personal experience.

and some more stuff:

So far, I don't like what I hear or see in the charts, but until I build the best I know how I can't claim that full range is a pipe dream. I think so, but I will try to prove myself wrong. One basic problem that could impact desk speakers is size. The light weight cones needed to get any semblance of treble means high Fs and large VAS. Darn physics.
Driving from a computer totally changes this - it is far better and more accurate to compensate digitally and with the right software you do not finish up with phase differences (yes even in a single driver you can introduce phase differences)

If you are talking about Jeff's i think you are mis-judging his monitor size. They are LS3/5A size -- there is (or will be) a version for FF125wk, it barely fits in the limited width.

We refer to Jeff's speakers as milliSize, and there are versions for A6.2p, CHR70.3, EL70, Alpiar 7, CHP/CHBW, FF125wk (+ a number of discontinued drivers).

If you need something smaller, FF85 in uFonken.

Due to some fortunate events I'm now able to build the fonken enclosure!

Are the plans for the enclosures public? I know about the plans on the website but they are quite old and the fostex drivers are discontinued..

cheers

Typically i put up a Classic Golden Ratio version of each Fonken/miniOnken up for free use, and full plansets (some are running 30+ pages) for a modest subscription price (free with the modified drivers i sell).

There are also free for FE127/FX120/F120A, and a few others.

Paid plans are available for Fostex FF85wk, FF125wk (other WKs in development), CSS EL70, Mark Audio CHP/CHR/CHBW, A6.x, A7.x, A10.x, A12.x, and beta versions are in development for Eminence 12LTA, Audio Nirvana Cast 10 and Neo10, and Tangband W8-1880 (i think that is all of them).

planet10-hifi miniOnken Plan-Set Subscriptions

and to help with the lexicon (a bit dated but still relevant)

fonken-style box nomenclature... what is with those names?

Thanks for the quick reply!

So that'll be about 30 for the Alpair 7.3 enclosure. I'll think about this.

cheers,
hurtz
