Kuei Yang Wang once played with RFT L 3401. He was not impressed. Try to ask him.

By the way: How is your German? You could get more help in some german loudspeaker forums.

Some of the old RTFs are good -- RFT was a large East German OEM so there was a large spread in terms of quality.

The Philips full-ranges are quite good... the older alnicos particularily so, but the newer ceramic 5s & 6s are no slouches either.

indeed, i didnt knew that there were so good things so cheap,
i have found excellent phillips drivers, a guy sells them, there mucg better then the greencones, (he also sells his 2a3 which powered it) it wont go more then 60 euro for a pair, and the same for 8 inch greencones that are in super condition. SO thats exatly what im gonna buy, even for my borther and friends also if it works out fine for me.

But i want a sub and a supertweeter. Even if it sounds very good without. Because i like very deep bass,

BUT NOW SOME QUESTIONS

1) i want to build an woofer, i dont want cinema, i just want extreme fast, clear, transient bass respons, so i got to go for an sealed box i think. what do you think ? Which drivers i gotto buy: i need specifications, because i buy on ebay, so im depending on what they are offering. 2*8 inch of 1*12 inch ? the problem is, that i wanna make a speaker with on the botom the woofer,
the full range in open baffle and the supertweeter : just like the next picture

Click the image to open in full size.

2) the next problem is offcourse : will the enclosure of the woofer not disture to much the full range ? (i expect that the full range comes it at 100hz or even more). (so mayb it is better with one 12 inch drive then two 8 because of the hight.

3) does anyone has specs of the greencone 8 inch, or the philips 2028, dont find anything.

4)how much energy is going into the drivers, the fullrange is always very limited qua wattage, (off course its high efficency, but maybe the woofer will not be, so we will see) But just for knowing, i think a lot of the wattage is going into the woofer and less into the tweeter. Is that so ?

5)since im a beginner, im gonna put up a measure system, im gonna buy a monacor electret mircorphone, and starting measuring, what software do you use for this ?

well, every comment is more then welcome
thanx a lot guys
