Hello,
I never heard a RAT System (i live in Europe Austria), but i heard a lot of ported boxes, where the lower frequencies seem to run behind the rest. I wonder if this is due to the huge group delay around the tuning frequency, or what else could cause this? Did not hear similar behaviour with closed boxes and horns. Especially with ported tops it seems they have this problem.
And if i look at measurements (Burst), a closed one needs 1-2 halfcycles to reach full burstlevel, while the ported one needs 5-6. Which indicates slow response?
Any ideas?
Thanks
martin
