I’m not sure on the subwoofer, I’ll need to do some research. Currently I find the low end adequate for the music I listen to, I’ve got the EQ flattened out and their “Auddessey” filter off. These speakers were unexpectedly acquired so I’ve done no planning whatsoever (did I mention they were free?)
Currently playing with toe in and positioning in the room, trying to find my sweet spot.
Pulled the cap out with electrical tape, vacuum cleaner was the next option, mouth naturally the last resort.
