I have always said I was not interested in taking measurements. Now you know not to take any notice of anything I say I have very recently got the urge to start taking measurements of my speakers. Not that I don't trust my ears but if there are small changes I can make for a better outcome without changing the design principals (3 way, semi omni, isobaric, no xovers) then I don't see the harm in it.
So for in room measurements I will need the following (I think?)
REW software for laptop - (free?)
minidsp miniDSP UMIK-1 Omni-Directional USB Measurement Calibrated Microphone - £93 approx.
Will this little lot be good enough and do everything I want ?
I've used this to measure all mine. It is not the most accurate measurement method, but it is good for looking broadly at what a speaker is doing in room.
I used it with my metronomes to nail down the inductor value to cut the top off the 6" driver and blend it with the tweeter cap value.
It will show peaks and dips in the in room response.
You will need to either burn pink noise or a log frequency sweep a CD and play it, through the speakers or have some other way of playing the pink noise or sweep through the speakers.
Then once you have measurements, interpret them. Which is the hardest part.

I don't have a smartphone so using that app is impossible. The only thing i have available is a windows 10 laptop.
I believe if i install REW it includes a signal generator ? I then need to work out how to connect the laptop to the hifi and use the signal generator and the measurement at the same time.
This is supposed to be an enjoyable hobby. All that i have read so far seems to point to it being more like a chore .
The sort of thing Rudy Bozak used to measure way back in the 1960's as a demanding test of how speakers handle bass transients.
You don't get results in numbers, but you do get visual results that show how shockingly bad speakers are in this respect - especially slimline ported speakers.
Just thinking if you're going to measure your speakers, you might as well measure something interesting and something that no modern speaker manufacturers nor magazines appear to do - presumably because they'd be too embarrassing.
