[OneStoneAudioPhysics]

guess that sounds like crap....

[cornflaker]

Prob just the mic

[OneStoneAudioPhysics]

I wrote "I guess" not "I hear". Those little vented cabinets distort the sound quite a lot so I personally do not like them. That's why I considered it to sound like crap :)

[cornflaker]

Haha so you did, but ported enclosures don't distort the sound [i]that[/i] much do they?

[OneStoneAudioPhysics]

They do distort the sound heavily when the port is tuned to a low frequency and that is exactly how those mini subs are built.

Check the group delay of such a design and the impulse response and you will understand what I mean...

[uN1Qu3DZ]

they are built for loudness not clarity, what do you expect. it's a pc speaker not hifi. and it's good for what it is.

[manutd36]

If your talking about Ported subwoofers then the idea is to make the bass deeper and the reason it sounds distored in the vid is because the camera cant pick up the bass.

[OneStoneAudioPhysics]

the port is a resonater which needs time to oscillate properly (which means with maximum amplitude). Most ported designs are calculated to get as deep as possible what results in poor damping and therefore "boooom booom" sounds instead of tight, hard bass.
