Full Version: Porting for SQ???
Mobile Electronics Australia > Mobile Electronics Discussion > Sound Quality Discussion

Is it possible? I wanna get the biggest sound out of my 10"'s but i don't want them booming at certain frequencies. Can i still get good SQ whilst porting?

Setup is 2 10" w3's running from a bridged jaycar 2x150W amp each. Box will be about 1cu ft each.

Any ideas on port lengths? diameters? etc?

i'd probably try going a little bigger, and tune low, as close as you can to your FS, mayeb a couple of Hz higher.
what's teh T/S specs on those subs?

FS = 28.8Hz
Qts = 0.475
Qes = 0.503
Qms = 8.260
Vas = 1.66 cu ft

Dual 2Ohm voil coils can take 125W each (250W max RMS).

The site suggest 1cu ft with 3" by 14.4" port.

It's ok to have bends in the port right? I'd need to use the width of the box to run the port. But i'd need to port to the front.

Looking at those specs.....the "general" SQ principal of tuning close to Fs applies.
It is prob a bit marginal for porting but should work quite OK.

The big issue is gonna be to deal with the port length you will need to tune low in a smallish box. I'd be inclined to use a single enclosure with the 2 drivers in it to help out, maybe 80 litres tuned 30 Hz with twin 3" ports about 320mm long. port speed a little high, but not too bad and you could add a flare to keep it nice and quiet.

You could go smaller but the ports get longer and IMO the thing will simply sound better in the bigger enclosure if you can find the space.

Hope that helps. Will go nice and deep too
