Ported or Not?

I hear a lot of people say Ported is the way to go, and to have it closed sucks. And others say closed is better

Here is a video of a guy with a good setup to get that much bass, but his box is closed.

I would put the type r in a ported box personally tuned to around 34hz or so.

Btw, closed is called sealed.

Also to add on, typically sealed boxes yields better sq and a ported box will be louder. But a well built ported box can sound just as good as a sealed box and be louder.

ported boxes are louder but only when there hitting the notes the box is tuned to. sealed boxes are cleaner and louder throughout a bigger range of frequencys. sealed for me only. had ported and will never port again if im doing my normal daily system. as for spl go ported.

1. It depends on the driver in use.

2. Ported has more volume capability with the same driver and amplifier at the tuning frequency where the system resonates. If designed correctly, it can have very good SQ. Taking a look at high-end home speakers, you can see a lot of them are ported designs.

3. Sealed designs have a lower order rolloff, but it starts earlier where bass-reflex designs have a lower rolloff because of the resonator contributing to output. When sealed designs are too small, they have a distorted FR where there's a bump at system resonance (higher Q) and loss of lower frequencies. Some people actually prefer this, though.

In the car environment, sealed is normally the way to go for SQ because of the tuning limitations of a ported design. Some drivers are better with ported designs in a car because they either are low on output already (and so more headroom = less distortion) or their T/S Parameters and design topologies wouldn't lend to good performance with a sealed enclosure.
