I have an Ashdown MAG 300 (300w) and a Yorkville Bassmaster XM100 (100w) when I turn my Ashdown up half way it's loud, but not too loud. It's just perfect for bedroom playing. When I turn my Bassmaster up 3/4 of the way it's way too loud for anything. Why is this? I know that watts don't equal volume, but I'd really like to know why this is.
