Have a look at Open Baffle response
So you're saying the published response is BS? For sure, an OB isn't going to alter its on axis measurement above the OB's baffle step nor is it going to be any different in a back box of the same baffle width, driver orientation.

OK I see what yoiu are saying about the rising reponse on the published data.
To be honest I don't trust manufactures much these days.
I regularly test manufactures products that are meant to meet Mil Specs and they often don't perform as published.
I don't care what they have measured because I don't know how they measured it.
I only care what I get in my listening room

Hmm, rising on axis response drivers such as this one are designed to be heavily toe'd in with 30-45 deg being common.

Can you explain that more.
I would have thought speakers that have a rising response, you would want to have them facing straight ahead so you are off axis to compensate for the rising response
I will try and explain the room.
The ceilings are 2.7m high but vented to the atmosphere .
The width of the room is 5.5m but then widens to 7.5m and then goes back to 5.5m
The length of the room is 17 m.
There is a wall that is 2.5 m wide which runs across the width centrally positioned so there are two 1.5m openings on each side (there are no doors)
The wall is positioned 6m from the rear wall.
The rear wall does not run across the width of the room it is 4m wide and there is a 1.5 wide hall way which extends 5m to the door.
I bet I confused the hell out of you. Hahaha
The speakers are tested 1.5 m away from any wall (one of those wall is non-continuous)
The house is open plan

highly improbable a voltmeter can make do with anything above 100Hz.
you need an oscilloscope
OR: send the speakers a 50Hz signal ONLY, measure it with the fluke and hope it's the same voltage that is sent when doing the sweep
(how long does the sweep take? a couple seconds?)
