 Partsexpress lists several. I see them in other places as well. What y'all said jives up with what I'm reading elsewhere; that subwoofers with freq responses much above 5-600 Hz are just woofers masquerading as subs. They referred to them as pseudo-woofers; regular woofers capable of producing frequencies in the 20-30 Hz range. http://www.partsexpress.com/pe/showd...number=290-367 http://www.partsexpress.com/pe/showd...number=297-608 http://www.partsexpress.com/pe/showd...number=296-432
So, what happens when one builds a sub using a driver that is not exactly a "true subwoofer" [and you still limit its upper freq to 150 Hz]? Let's say you have a woofer that has a freq response 30-3000, specs are otherwise good, it models okay and has been used successfully as a sub before. Think it's worth spending time on?

Of those the Peerless is the only one I'd really classify as a subwoofer (it's frequency response is listed as 18.1 Hz to 500 Hz as well). It's a great driver too... the Xmax isn't as high as some other drivers, but it is supposed to offer great SQ from everything I've heard about it.
The Goldwood driver I would not classify as a subwoofer. With an Fs of 38 Hz and an Xmax of 3.5 mm I would definitely classify it as a woofer. The Aurum Cantus 10" claims to be a woofer anyway. It looks like a nice driver (and should be for the money).
There's no reason that a driver with response up to 3 kHz couldn't be used as a subwoofer, but IMO you could do better than a low frequency response of 30 Hz. If all you're looking for is a lower limit of 30 Hz then there's no reason not to use the driver. Of course it depends on the specific driver...
