A fairly easy question you can answer on top of your head. I still own 2 units(New) of your M130, 5" drivers(in fact I own 4units so far used 2 units).
I found the midrange performance to be very good. I want to design a sealed enclosure for this unit. So can you advise me:
1. Optimum size of the enclosure, for the maximal flat roll-off at the bottom end?
2. What is the -3dB freq. at the bottom end?
BTW enjoy your Youtube channel. Thanks.
* I want use them as Omnidirectional driver, so no baffle step is required.
