Tang Band W3-1401sd; am I missing something?

[type]

Just checking out this driver on Parts Express and can't figure out how this driver can claim an Fs of 75hz. Based on the manufacturers provided response curve it looks like it's dropping off well before 100hz.

Here's a link to TB's spec sheet:

seems OK. fs is determined from the maximum in the impedance curve. and with the low qt value, the early roll off can be expected.

btw: finally a TB 3" with a usefull Xmax!

Edit -you beat me to it. Anyway, concurred, it looks fine to me, based purely on the manufacturers published sheet linked to. Impedance peak on the spec. sheet indicates Fs is at the 75Hz stated, & the mass corner of 2Fs/Qt = 483.87Hz matches the FR curve.

Thanks for clearing that up.

So this one should have the high frequency performance of a 3 incher with the bass output of a 4 incher (same Fs as the 4 inch bamboo driver). Except for the low sensitivity it looks like a great little driver.

Manufacturer response curve is usually on open baffle. You can get more bass by using horn or bass-reflex enclosure.

Yes, that's the usual trade off.

Did you get a look at this one? Wish I had a few extra bucks lying around to compare them to each other.

The Mark Audio are much more intriguing to me than either of those. Tang Band has yet to win me over, they have too little consistency, too many models, and don't seem to spend much time refining things before shipping.

Their 8" fullrangers do seem superb though.

Interesting 5" I havent noticed before

Maybe this 4" could be worth a try

Henkjan,

>finally a TB 3" with a usefull Xmax!<

Don´t fall into that trap unless you´re talking car subwoomphers. A driver pumping like mad is a driver loaded with LF it can no way convert into SPL. Back to the drawing board, have a dream about a horn really loading the driver.
