I am new here, I have just started researching how to build a tuba sub. I am looking for all the info you guys can send my way. My current setup is a pair of LSI Splits and a pair of KP 480's. I just picked up another 480 and I was wondering if the driver and xover would be suitable to use for a tuba? Also, anyone have a good diagram of the box design. I have a large shop 2000 sq.ft. that I listen to my system in so the box can be as large as it needs to be within reason lol. I am looking to get the bass as deep as possible.
