Re: Diy sub

I don't have enough experience with these DSPS perhaps someone else might chime in but my understanding is that minidsp has distinct advantages and with the mic you not only implement the filters but also measure, set up and eq your entire system.
I actually would have anticipated that you would be asking more about the details of building the boxes. Perhaps you've understood that aspect very clearly.

It's 18hz not 15. You just get the dsp you want (minidsp, the higher types of dbx driverack, behringer dcx and I think rane dsp) and you simply key in the settings for 3rd order 18hz highpass and you're done.

Re: Diy sub

I'm not sure if your reference to svs port is a consideration of changing to a slot /square port. If you do that you must take care that the slot port surface area equals the sum of the surface areas of the two 3.75 in diameter ports and the port length will need to be re-simulated.

If the intended net volume has been accurately implemented, all you need is 1.5 inch acoustic foam lining the internal walls of the box to kill resonances.
