I was hoping to get plans for the 12pi, please and thank you. My head has been spinning the last few days deciding on which sub to build, labhorn, titan48, keyhole sub, 12pi. I finally decided go big or go home! So here we go thank you so much.
hi new poster would very much like to build the 12 pi subwoofer look at many other design and choose this one is there a preferd chamber volume for the speakers would like to keep them as close to design breif as poss or would the change in volume make no noticeable difference not really seen this design here in the uk ofcourse the lab sub has made it here

Not sure what you're asking, but both front and rear chamber volumes are critical. Stick with the dimensions shown in the plans for best results.
Front and rear chamber volumes are important in any horn design, but even more so in the 12π basshorn subwoofer, because distortion reduction is accomplished by maintaining symmetry in the load. Push-pull drive is there to cancel asymmetries, so we sure don't want to introduce any.
