Measuring an inwall speaker, out of a wall, will always produce undesirable results.
Which is also why it sounds bad.

Thank you for taking the time to respond. I felt that I had acknowledged that it is to be expected that the speakers won't perform well when not used as intended.Measuring an inwall speaker, out of a wall, will always produce undesirable results.

The true purpose of my post is to ask about ways of measuring performance in a quantifiable way. That is to say, in a way that is repeatable and doesn't rely on opinion.
Like Russdawg said you can get a Umik 1 and REW to make measurements but you definitely need to put them in a box before doing that, the reason they sound bad is because the front wave of the woofer is cancelling with the back wave and making a mess of the frequency response.Thank you for taking the time to respond.

Lots of free info on the website too.https://routledgetextbooks.com/textbooks/9781138921368/You might want to buy Floyd Toole's book.
The JBL SP8ii are an "infinite baffle" design. Before measurement, they should be put in a baffle, (such as a wall.) They should only be put in a box, if the optimal box volume is known. The box volume can be calculated from the Thiele-Small parameters of the driver, (if they are known.) https://en.wikipedia.org/wiki/Thiele/Small_parameters If they are not known, it is best to ask the manufacturer for the minimum box volume and the optimal box volume.Like Russdawg said you can get a Umik 1 and REW to make measurements but you definitely need to put them in a box before doing that, the reason they sound bad is because the front wave of the woofer is cancelling with the back wave and making a mess of the frequency response.
