The Boominator - another stab at the ultimate party machine

Choosing another driver doesn't mean to randomly pick anything. In allmost any case a change of the tuning is needed. Nothing that is impossible to do with a few data and a simulation prog. I have seen more than 120$ asked for the original driver, which makes the construction very questionable.

Picking different drivers means likely design changes.

Below are T&S parameters you should look for if you want a substitute. Additionally I've included a few screenshots around the box tuning. This is a bit of an unusual design and this is a DIY forum so DIY as you wish! I haven't found anything that does loud, sound quality, and long battery life as well as the boominator.

I'll try to find the Boominator digest I created some time ago and upload it for reference. I created it because this thread is HUGE and it's hard to find useful information.

I was looking at candidates for different woofers and came across the Faitalpro 10FE300 4ohm. All T/s parameters are close except for Le and Re.
Why does Le have to be this high? Is it for to play the freq all the way up for where the piezo takes over? If i were to build one i'd probably go 1" compression drivers and dsp anyways. Here's a link for those who are interested 🙂
