finally have my needles up and running, with hivi b3s drivers! thread on it here. a quick pic:

Click the image to open in full size.

overall impression is that they're the best speakers i've ever owned, and create quite an impressive 'wall' of sound especially for such small drivers. that said, the sound is a bit edgy at the top end (even with zaph's breakup node filter) and the bass really needs a hand from my subwoofer.

so even though these are the best speakers i've ever owned, i can quite easily imagine how they could be better.

dan from darcher audio has told me the alpair6's are really in a totally different league to the hivi's, and henkjan if your simulations are anything to go by, they should prove stunning in my needles!

(henkjan, i assume you also tried the w3-871s in your simulation?)

(NB: in the sim, the HiVi had less low end output than the W3, a bit the same as the W3-1285 that I will upload in the next post)

and yes, this does sound too thin without a sub.

thank you very much for this, henkjan, it is extremely useful.

i have combined all 4 graphs into one:

from top to bottom, they are:

1) alpair6
2) bb3.01
3) w3-871
4) w3-1285 / hivi b3s

it appears that a driver change is definitely in order, especially when only the b3s and alpair6 are shown:

corrected the first graph above, the w3-871s was horizontally misaligned (please refresh to see the proper graph)

henkjan, is it possible to show the Vifa 9 BGS 119/8 simulation as well?

thank you for the extra graphs!

there are now too many to show on one graph, but it is still clear that the alpair6 is the best choice. frs8 and b3s really seem like horrible choices!

unfortunately i cannot find an australian source for bb3.01 or 119/8... so it seems the alpair6 is the clear winner here as soon as dan gets some in stock.
