I have no personal experience with that one.

I can't seem to find any W3-871S around.. can somebody suggest a suitable replacement? I built my Needles with the FRS8's, but would like to try something a bit nicer... Thanks in advance!

I would recommend the Alpair6 (see above), or the Vifa 9 BGS 119/8.

The B3S is not balanced in the high end, and has a poor low end in the Needle. both the above are excelent drivers and suit the Needle very well.

b.ugger... just ordered the b3s for my under-construction needles! oh well, not exactly an expensive mistake at $19 each

edit: hmm seems like i can't find either of those drivers in oz yet. guess the plan with the needles will be to live with the b3s until i can get some cheap 871s...

Henkjan, what software are you using for your simulations?

[Henkjan]

I would have exected that Dan Archer should have the Alpair6s in by now...
As I write this, I just paused from some measurements on the Alpair6 in the Needle... I have notch that at least measures fairly well, so after some more finetuning I'll hook up the other speaker and listen....

for simulations I use MJK's mathcad sheets.
notch filters I don't simulate, I just measure with a box full of caps&coils available...

btw: I could send you a pair of W3's but I expect that for the shipping costs you can by the Vifa or Markaudio localy

I've got Omnes Audio BB 3.01 drivers, not in needles but in BIB's, they're very nice. Faultless as far as I can hear, though not quite as sweet on some instruments as Fostex.

According to Dan, the alpair6s will arrive around the end of this month.

thanks for the w3 offer, however shipping would be prohibitive yes!

I just checked: shipping from here to Australia is 24 euro's for a parcel up to 2kg

the first notch did not quite sound top (so some work to do), a bit of a nose sound to some voices, but at least I got some CD's to judge the Alpair6... I'm already impressed... well balanced, powerful (for the size that is) low, beautiful detailing... yes, worth the extra investment compared to any other 3" driver I've heard....

works out to about AUD47... may not actually be that bad value given that local shipping here for 2 3" speakers is AUD15.

that said, i'm sure some 871s will make themselves available in the future... so i'll probably try the alpair6 units first. after i have a good listen to the b3s though

read this thread for the first time from start to finish... seems to be an eternal thread!

didn't find any concrete results from using the hivi b3s in the standard needle design, but i'll be sure to post my results as soon as my hivi's arrive! mine is the standard design, except with front and back using 16mm mdf as well (looks thinner in the pic below since the inside is chamfered 45 degrees)

waiting...:
