Hello,
I am atatching one plans for 8" driver plus 1" conpression driver. The second atatched file has several plans, in the pag. 11 there is a enclosure for a dual 8" plus a dome tweeter.
I hope it will helpful for you.
I am looking for similar plans, but I know finally I have to calculate it in order to get it, because is hard to find that i want.
Best regards
