Looking a custom sub from PSI. The EPM is 44.09...leads me to think sealed is the best option but how would a 30HZ ported sound? keep it small? what do the experts think?
i sent you a PM. this is a timely issue and i would love a response. thanksThat's really something that has to be designed for. I'm sure it can work just fine, just with a smaller chamber volume and a much larger and longer port than normal. Its hard to say by just basing it on a single spec. But likely if it can work in a small sealed, a high compression ported design can suffice. Really depends on a lot before that can be proven for your specific request.
