Bassleg 15"
This post describes my bass extension stand for the Aktiivinassakka speaker build. As mentioned in that build post, the midbass driver is closer to a midrange driver and I think it will benefit greatly from added woofer, that will make it a 3-way as a whole. The idea was to build a bassleg to give more capacity and power to low frequencies, but not to be a real subwoofer. That would give target frequency low frequency of 30-40 and upper frequency limit of 200-250. The midbass of the main extends easily only to about 200 Hz, so that's one good reason to not design for a subwoofer here. I got subwoofers that I can still use. The size of the bassleg should not be much bigger than the main speaker so that they could be nicely stacked. The depth of the speaker is 35 cm, so that's also the target for the bassleg. I had commercial subwoofers in use, but their capacity (maximum SPL to lowest frequencies in music) was not even close to what the main speakers could do. I had a stack of ...
