My guess is it would work, but be far from optimal. Most ribbons are lucky to get to 2.5kHz, and even though the spec sheet shows the 10" peaking at 3kHz, it's directivity will be beyond its pistonic range and beaming by that point. Most 10" drivers will not be able to handle wavelengths above 1.2kHz to 1.3kHz, and due to the driver being what it is, it will likely not even get that far.BTW- the manufacturer's pdf says this driver is 4 ohms, not 8 ohms, so that also puts a kink in the idea.

Specs show 8ohm and picture shows 4ohm which one is it

Asked by: VusstoppyPro
pdf also shows 4 ohm impedance spec, and that is from the manufacturer.

In terms of SQ, how does this compair to the AC-250F1 10in or the AC-300 12in?

Asked by: Mr. Bigs
Sound quality is completely subject to opinion, so unfortunately, this is not the type of question that we can answer with any degree of accuracy. You may prefer one kind of sound, I may prefer something different, and your neighbor may not be able to distinguish an appreciable difference between four different woofers.

Is this a woofer or a subwoofer? How would a pair of these perform as a subwoofer in a ported box in my car? Say in comparison to the Dayton HO 10"? I have 500watts of power.

Asked by: miniSQ
This will be classified more as a woofer than a subwoofer. The Dayton HO 10's will provide more output in a smaller box.
