Hello there. Im planning the DIY build of a kingdom replica. Im trying to backwards engineer the Kingdom 18. I have some questions.
How can a speaker Cabinet measuring 100x85x160 have an internal volume of 370L? Is this only the woofer or total volume? I came to around 1.3m3 excluding wall thickness. If i calculate the walls to be 8cm thickness i still get much more volume.. Also can anyone meassure the diameter and length of the bass ports?? I hope to gather as much info as possible to make a good replica. How much is the midrange DC driver volume? I hope anyone knows.. If there are some schematics of the Filter those are welcome too.
