I'm considering a 4 ohm Acme B-2 cab for my GK 1001RB. I'm playin' a passive 5'r for gospel, jazz, r&b,funk gigs....no dinosaur metal tribute gigs. I have seen others play 800 watt @4 ohm class "D" amps (Iamp 800) thru this cab with ease. I'm wondering if the new "H" class amp that GK offers, could keep up with a slightly higher wattage class "D" amps? GK states that the "H" provides smoother and quicker transient response, when slapping or playing aggressive rock. I'm not looking to cut thru a guitar ladened mix, just a small gospel rhythm section...20 voice choir.
