This topic interest me, especially since I bought this afternoon an MTX Soundcraftsmen A400 Pro.
I tried it with a par of Kappa 8. I know these speakers are hard to drive, but not as the Kappa 9. Anyway I tried really slowly with the A400 Pro and it shut down… or at least it seems to want to. I was waiting for any signal of that kind to immediately turn the volume and the amplifier down. So nothing was damage, then I used the Kappa with my Grand Integra M508 and they worked perfectly.
But could you tell if my A400 Pro, might have a problem or this is due to the Kappa impedance dipping below 4 ohm. Another strange thing, I couldn’t see the clipping LED flashed or turn on. Did the Kappa didn’t let them time enough to do so?
Could an A400 pro drive those Kappa 8. Now my plan is actually to use it with a par of AR 303a, will it be ok? (They have an average impedance of 4 Ohm and supposedly they doesn’t dip down more than 3.6 Ohm at a certain frequency).
Thanks.
