Porting Techniques

[kingpin_jeffie 10+ year member]

Im preparing for my upcoming switch to a HC18 or SX18 this summer, so Ive started designing the ported enclosure. Its gonna be a little less than 6 cubes after displacement tuned to ~35Hz. I know that to maximize spl you should avoid 90 degree angles to help guide the wave through the port. What I dont know is there any special angle i should be leaning towards? 45?, 30?, 67? I dont know. but if someone out there does Id be most appreciative if you could spread your wisdom. Also any other little tips would be helpful as well.

Thanks

Anyone have any other tips.

Perhaps Rangerman could hook me up with some SPL dust //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

go to home depot and ask for it, as well as dB glue.

avoid 90 degree angles on the port itself, or the entire box

please explain. ive never heard of this

They go by diff names for diff mftrs. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

iamapimp, it's exactly what you think it is. Some people believe that right angles are no good for SPL.

interestingly enough, bigbassman's preferred brand is fairy dust, and Dustin uses both fairy AND SPL dust time to time.

Fairy dust indeed...............

So is putting 45 degree angles in really worth the trouble of having to build the box bigger to accomidate for the displacement of the extra wood?

What amps are you gonna use? Don't for get to use amp coolant to keep the amps cool...

**** I just opened a dead thread from half a year ago. Go me.
