"tha-push-pull-15"
Two problems there:
1) the huge cavity the drivers couple into causes a big dip in the reponse somewhere, probably 80hz~120hz.
2) the drivers are so far apart that the expected reduction in distortion will only be in the bottom octave.
I admire your drive and energy in getting all these designs realized.

I know your designs from DIY audio.
Although i have my doubts about some of them i applaud your affords. You must be the most active/productive designer out there. |

Great thread, thanks very much for sharing. Great finish on the cabinets.
Maybe one suggestion is that on the port assisted 18" sub you could try a longer port with a 180 degree bend in it and make it twice as long? It Should lower the cut-off frequency probably at the expense of the high frequency cut-off!
