Infinite baffle application?
Would this woofer work OK in an infinite baffle application, such as an in-wall speaker or even in automotive?
No, with its Qts value of 0.19, this speaker is more or less the polar opposite of a good candidate for infinite baffle application. It will perform much better in a ported enclosure of appropriate internal volume. For infinite baffle or mobile audio situations, you want to have a Qts of at least 0.50, and the higher it is, the more effective it will be in your infinite baffle application.

Enclosure size difficulty
I have tried several enclosure calculators for this driver. Each one has produced an enclosure size too small to accomodate even the physicial size of the driver. What is an appropriate size enclosure and is it best sealed or ported?
This driver should perform well in a ported alignment, with an enclosure volume of approximately 0.42ft³. To avoid port noise, you'll want to use two (2) 2" diameter ports 6" in length; or, one (1) 3" diameter port about 7" in length. In either case, the enclosure itself will be tuned to approximately 70Hz, with an F3 frequency of around 65Hz. A larger enclosure will not provide significantly lower frequency response, but it will exaggerate the potential peak in the response around 70Hz. A smaller enclosure will minimize the 70Hz peak at the expense of low frequency extension.

Wondering if these would be a good replacement speaker for a set of Definitive Tech BP-10s
As long as the dimensions fit these should work, these are closer to a 7" frame as shown in the product dimensions..

Can these be used in a car door in infinite baffle? Will be crossed from 200-2000hz.
IB will not make much of a difference with anything above 200 Hz so I do not see a problem with this.
