Ok Wayne, I appreciate that what I am seeking is in fact the Eight Pi, but looking at the size of the cabinet, it looks to be - large - to say the least, 10cu.ft, whereas the Tower Two is half that. So this is what I am wondering is if I can use the cabinet of the Two Tower with the PSD2002 horn, rather than build the Eight ( which I am sure is a better solution), since 5cu ft is the absolute max volume I can do in the intended room.That said, I would still like to get the plans for the eight!... just in case... !!!!
Thanks again for you advise and help in this,
Derek
