I borrowed a Dayton Audio DATS V2 from a friend of mine to give it a go on some units I had laying around and I tried it too on my 4343/55 hybrids.
I have to add that all measurements were done with the units still mounted in the cab as I'm using external 3155 networks and every transducer has his own 2 pole speakon connector + cable.
If it makes any difference - each lead between the DATS and the back of the enclosure was 1.2m 2.5mm2 copper, same goes for the internal cabling.
Test settings:
Anyway, this is what came out
LEFT SPEAKER:
2405H
2450J+Radian 1245-16
2123H (again - it's mounted in the enclosure!)
2235H (see above note)
RIGHT SPEAKER:
2405H
2450J+Radian 1245-16
2123H (again - it's mounted in the enclosure!)
2235H (see above note)
