Hi, All. I need some quick feedback on choosing heads. I'm going to be running a Goliath III (4 ohm) with either the Eden WT-800 or WT-400. I'd like to use the 400, as I can find one quite a bit cheaper but I don't know how much clean volume I can expect out of it. The largest space it will need to fill is medium-large (I'd say it's on the smaller end of large, if that makes any sense) church building. The acoustics are terrible but that's another thread... Anyway, I'm fairly sure the 400 will be enough power but I don't want to put out the cash only to find it's not loud enough or starts losing clarity or depth. What do you guys think?
