Building sensitive speakers

[sifis_samos]

Hi guys, i need your advice....i recently build a pair of speakers using a pair of 4" focal car coaxial speakers, but the results were a bit dissapointing...
So i am at the quest of building a pair of sensitive speakers, that will be driven by a Chinese Tripath amplifier, giving about 2x20WRMS at 4ohms...i consider buyng from Madisound.com ... i want to spent maximum 100euros.. so any advice is welcome!.. i am thinking of using a pair of 4" Full Range speakers, as Fostex FE127E 4.5" Full Range Shielded or the Fostex FF165K 6.5" Full Range

I dont want a too big box so maybe a vented solution is ideal.
I am mostly interested in melodic reproduction, and i dont care so much about bass.. i listen too much rock, metal and Greek folclore music that uses guitars etc..

another solution i consider is using a Peerless SLS 830945, 5¼" Woofer or a Hi-Vi F5 Kevlar/Paper Cone 5.5" Woofer coupled with a tweeter as a Hi-Vi TN28, 1" Top Mount Fabric Dome Tweeter.

any other suggestions?..

FE127e, at least once fully tricked out, is my favorite. The Fonken & mFonken are 2 smallish boxes for it.

The big amp i use with mine is 20W. The better amp is 4W.

There is a reason i like full-ranges, i believe XOs are "evil".... and on a budget, 1 driver vrs 2 + XO, you get finesse vrs brute force. The 2-way will go higher & lower, but not that much, and the FR will do mids better.

anyother options, perhaps slightly bigger than microFonken?
I ask because these speakers may be used in the future in my sitting room so a so small spewaker might be too small..

Those are actually milliFonken (4.5 litre) . the uFonken are smaller (2 litre). I've yet to draw them up yet, but both centiFonken (~7 litre) and deciFonken (~10 litre) are in the queue. The FonkenPrime (13 litre) is the granddaddy of all of these and still our reference for everything.

hmm...the Fonken (Fostex FE127eN) looks very attractive and doable actualy...at a first glance seems a bit confusing but it certainly looks great..how about performance?..i mean by your experience, how does it sound?..colouring as tube or more to solid state sound?

[sifis_samos]

just a quick silly question..Fostex FE127E is the same with Fostex FE127eN ? Because at madisound.com i can find only Fostex FE127E for $42.70 ...

also are we talking for the same think: http://homepage.mac.com/tlinespeaker...-1v01a-map.pdf ..

do i need any kind of crossover for this project?
an external tweeter as Hi-Vi TN28, will it help at higher frequencies at all?..perhaps crossed high up to 7-8k..
ending, is it worth getting the Fostex FE108E∑ for the same project or not?..
or would it make a big diference if i use a different speaker other than the Fostex?..i am asking because its is very dificult to buy fostex speakers in Greece and i have to order them from USA (About 50euros shipping).. i can easier find Audax, Scanpeak,Visaton, Peerless...

We like it a lot. A common phrase around here as we try new driver or box is "its good, but it isn't a Fonken". Quite a few have been built so there are less biased opinions

Yes, same box. Slightly changed since i did this illustrative visualization.

...colouring as tube or more to solid state sound?

They really like tube amps & higher output impedance SS amps (some say the FirstWatt F2 is a perfect amp for them, we haven't built ours yet.

They certainly aren't sterile as one often associates with SS.

Note that my comments always need to take into account that mine have FE127eN ... those are the FE127e that i take & transform to a whole new level of performance. (all the info is availaible to diy the driver mods as well)
