This little driver seems to outperform everything else!

I've been experimenting with Hornresp for several years now and have designed horns for 100s of different drivers, and have built several of these designs as well, and in the last few months I've been experimenting with the Tang Band W1-1070SE and it's capabilities in a horn enclosure are second to none. I've experimented with configurations of a single driver upto sixteen drivers per tower and even a tapped horn subwoofer with 100 of them and they will do anything and everything and do it extremely well. Because they are so small the thin metal cone is very stiff the motor is quite strong and when used in multiple configurations the drivers can be arrayed not only for desired dispersion and directivity but in such a manner to come ever closer to that "pulsating sphere" idealogy. The hornresp models show an almost perfect impulse response and frequency response can be made however you desire. The best part is that the drivers are cheap have very good excusion and four of these in rear loaded horn should out perform the Fostex FE206 and do so in a smaller enclosure. I think I'm in love with this driver!!

Hmmm...

Go easy on the eggnog fella.

[brsanko]

Mmmmm....eggnog!

Interesting. I love the miniscule Vas, and the Qts of .40, but how do you deal with the Fs of 170Hz?

[brsanko]

in a horn the Fs doesn't really affect bass extension, you just have to make the horn longer to go deeper. now the small size means that to get much volume at low frequencies you need to use multiple drivers though. My friend Doug made some nice little bookshelf units with one each of these that go down to 80hz or so but without a seriously sharp high pass filter they start to pop when you put any volume to them.

That 81 db spl doesn't look all that good either.

[brsanko]

Once again almost irrellivent in a horn. But seriously it's a one inch driver, you take four of them suddenly it's 87db and still under $60. With an almost perfect impulse and the fact that the 1W spl jumps to over 100db in a properly tuned horn encloser none of these things matter. The only specs that really have any meaning for a horn loaded enclosure are Q, VAS, Xmax and mms. Mms is probably the most important one of the bunch when it comes to dynamics and distortion and probably no one has even noticed what it is.

4 of these sounds like a nasty bout of comb filtering unless you have some kind of tapered lowpass system....

[brsanko]

Nah, you just have to carefully array them. It's a bit of math but the results could be astounding.

I'd be keen to give the pulsating sphere a go if only they were cheaper. Even with wholesale pricing at PE it's still a fair whack to make a pair of spheres.
