If you are doing it with second hand pairs then of course these issues will have been worked out .
but once again I personally would question the importance of driver /enclosure compatibility measurements and would just say try it and see.

The science here is clear, its covered by O level Physics, Its application to loudspeaker design is where it gets more complex.what measurements show the effect
Look, Phil, we all get it, you don’t like the owner of NVA.I asked Richard for advice on this project, and he had not a clue,
Not true Nick.

I'm not critiquing him, just making an observation.Daniel Quinn wrote: ↑Thu Apr 20, 2017 4:07 pm Firstly I was putting words in RD mouth , I may have been paraphrasing but it is unfair to critique him based on what I said . But you have taken it out of context .
RD manufactures speakers which he believes are the best .This is refreshingly honest and a good thing , it means there is an honesty to his designs that he believes in and he is not just making them for the money . Last night I was reading an Audiophile magazine from the middle 90's I think , and there is test between an NVA amp and Creek amp and the NVA amp won for sound quality . In this mag they gave the manufactures a right of reply , lets just say RD as not changed in 20 odd years . But he does say , the reason NVA did not make a tuner is because they cannot make one better than creeks for the money creek charge .
In my opinion if you make hifi that is reflection of your passion and your ideas it is incumbent upon you to believe it is best and that they necessarily means you must believe that other ways of doing things are flawed .Otherwise you would be a charlatan .
It does not however mean you believe your way is the best for everyone and that others ways are not as valid , it may mean however you believe they do not sound as good .
but if you make something with honesty , pride and passion and yet you believe there is a better way ,then you are in effect an arse .
I have no problem with RD claiming acoustic suspension is the best way and all other ways are flawed { if he does } , you pay your money you takes your pick , I would expect other manufacturers to believe the same of their designs , alas , I only believe the majority would bullshit me.
