I have both the 600 and 500. And as we discussed before the 600 actually goes lower then the 800. So, that said, perhaps I just haven’t heard the right material yet (if hearing is the right word as at these frequencies it;s more about feeling)

I’ll propose a EP500 and a buttkicker LFE might the combo to hit it out of the park … after all a good kick in the but might be just the nirvana your looking for. smile
