For a sealed box and with these dimensions it can hit -3db(simulated measurement) around 95Hz and I use a subwoofer dial to around 100Hz x-over with it.
I am listening to it right now with the above combo it sounds great anyone building it will be happy. It costs me US$90 for the drivers(2 units) and the cabinet is very simple. I read many reviews on the best 2-way speakers and they one thing in common, the cabinet dimension ratios are very close to each other. I duplicated that dimension ratios the result is it throws a large sound stage(*) for such small speakers. Couple with no x--over it sounds really good and they are driven from a pair of common amplifier(15watts) with an integrated CD player.
* actually I intend to use it as my computer speakers, it exceeded my expectation. Mind you I have built a pair of Fe167E(left unused) before, I like these speakers better. I know what full range sounds like.
Cheers.
Hi, I'm quite interested in buying some of these, what was the buying experience like? Did you have to wait long? What import charges were there?
Thanks
It's a neodymium magnet, not to be confused with ferrite which needs to be much larger to yield the same strength field.
A slight deviation from topic. I bought a pair of NSW2 from this site, to experiment with a Pluto type design. He was very helpful in sorting out an (ebay) payment problem, delivery was very prompt, and the small speakers were very well packed. I haven't tried them yet but they look fine, I feel he is worth recommending
5 litre sealed is fine, I put mine in the same box size, sounds terrific(very open), I am listening to them right now.
Putting them in horn enclosure takes up to much space!

i think my double horn KORNETT will work
very good with a cheap invers driver in the back
like Monacor SPH-60
look my HP
measurements and translate the feedbacks!

Drivers on Zigma
Good evening,
As I wrote before I tried to put these speakers on Zigma's enclosure.
My main speakers are a pair of JBL en3 with s21 (in other word: a bigger L65), so you can image how surprised I was when I clearly heard the bass Moog on "The old castle" (ELP Picture at an exhibition) from those skinny speakers...
(2nd tumbnail)
I also compared them with standard fe103 on the same Zigma and on Pico-Lino coupled on the floor (as you can see). I think the latter solution gain a little more bass.
(1st tumbnail)
So, summing up, I think fostex are more natural on mid and high, but the chinese speakers can go really low and I think their response are al lot wider than fostex's.
I'll post more after the next 25 hours of playing.

Hi,
I have similar speakers, did you flush mount your drivers?
I found the highs are little more pronounced( I should perform some measurement to confirm this) and should be tamed, after more than 50hrs of listening.
Overall I really like this driver better than my Fostex FE167, they add more body to the sound reproduction, whereas FE267 sounds very thin in comparison.
No, i mount them straight over the wood without carving it. I use 12mm birch plywood, with 45° cut behind the speaker to let him "breath", so I couldn't make the front baffle thinner!
I agree with you: they give more body to the music than my fe103.
How did you tame the high frequencies?
I haven't fix the HF response yet, flush mount will obviously help, I strongly suspect there is a rising response.
My initial thought would be a simple parallel inductor and resistor value (a high freq.shelving equalization BTW, I have yet to measure FR) starts around maybe 6-8Khz.
or alternative
add a tweeter(or super tweeter) x-over at possibly 6-8Khz, a 6dB slope(on either end) may work. This approach will improve dispersion and directivity as well and at the same time will give you a smooth top end.
I have ever seen that 4” Dual Cone Speakers in China website.you will got further supprice if you can go there:³å×ê îÏ´Å4´çȫƵÀ®°È4´çȫƵÑïÉùÆ÷/4´çÀ®°È - ÌÔ±¦Íø
