Okay, but wait a minute. When do you ever connect a woofer to a piece of test equipment without the woofer being in an enclosure?
Wired as it appears to be on the site's home page, you can measure, what? DC resistance? Impedance above its useful range? Every other important aspect of woofer performance requires an enclosure.
Sorry, but this kind of makes me wonder if this company knows what they're doing.
How would you measure the free air resonance?
Woofers are tested on a baffle, all the time. No enclosure, just a baffle. That way, an enclosure can't influence the outcome.
Argue with the guy who designed it- John Murphy. He's an EE.
