Hey, I just posted the first steps of my first build which uses the RS225 (but a single one) and I am hoping that they will get as low as 30 Hz. From all the reviews I’ve seen, it seems that the RS225 can easily hit that at a great price point.
My current design’s height is 3.4ft but it includes a dedicated stand, which can be extremely shortened to make the speakers be at a minimum of 2.6 feet, or if you choose to make the port be back firing, then they are only ~2.35ft. Its internal volume will be ~1.7ft³.
May I ask if you did not mistake when introducing a filter? I check winISD by adding a high-pass filter, not a low-pass filter.
