Sealed Back Replacement
Can you replace this sealed back midrange speaker in a vented cabinet with a non sealed unit such as a Dayton with similar specks?
If you replace a sealed back midrange with an open back speaker you will still have to create a chamber behind the driver to prevent the woofer from distorting the cone. You can use something as simple as a dixie cup glued behind the driver for this.

What size are the terminals?
I need to know whether they are 3/16, 1/4, etc so I can buy the right connectors.
The terminals on our current stock are 0.110" (negative) and 0.205" (positive). I've linked the appropriate connectors below for your convenience.

What are the Thiele Small parameters? Does it have a accordion surround or a half roll?
I would tend to call those irrelevant due to the sealed nature of the basket. You do, however, need the frequency response graph and the voice coil inductance. (Judging from the Re, it is probably fairly small.) At the price offered, it is not unreasonable to simply buy one to test with woofer tester.

Is the grill removeable? Thanks.
No, the grill is not designed to be removed. That is not to say that it absolutely could not be removed, it is simply designed to be left in place.
