@little wing, what you have your "Subwoofer Trim" set at? and your "Bass Cross Over"?\n\n\nI'm going on memory here but I think the sub trim is set at 3.0, I believe. honestly I'm not quite sure what the subwoofer trim actually does to the sound . The manual says it's to fine tune the bass. I experimented with different crossover points, 90 hz seems to give me the best and punchiest sound with the ascend towers and the one rythmik sub that I have.\n\nI say I'm going on memory because this whole covid isolation thing has got me kind of down. So I flew home to Philly for a few days to spend time at one my favorite places called valley green. It's kinda like a rainforest. A little oasis for me. Back to Tucson tomorrow.\nI'm sure you wanted all the extra commentary, LOL.
