Seymore Posted February 26, 2014 Report Share Posted February 26, 2014 If you have adequate space for either of each ports, which are more efficient?I've used and built with both ports and haven't really seen/heard much of a difference. 2001 Civic LX SedanPioneer DEH-7500HD Big 3 in 1/0 Knu CCARockford P500-4RF Punch P165-S in doorsRF Punch P165 in rear deckFront doors deadened with DamplifierNextSQ's new HDS208 8" in a T-line whenever it FINALLY COMES OUT I CAN FINALLY AFFORD IT Bend over and I'll show ya. how is it 2 days work? half a day at most, i may be an idiot, but im not an idiot.

Joe X Posted February 26, 2014 Report Share Posted February 26, 2014 With aero ports air can travel faster through the port and it's ends without turbulence kicking in, so they can be smaller, also the wall thickness of aeros is negligible as far as displacement goes, both slots and aeros can do the job but the slot needs to be larger to keep airspeed low. The real difference is that it's really easy to change tuning with aeros if you need that. Link to comment Share on other sites More sharing options...

That last bit's what I thought too, but you can build cut-off blocks to go into a slot port for lower tuning too. I guess it's pretty much just an opinion at best. 2001 Civic LX SedanPioneer DEH-7500HD Big 3 in 1/0 Knu CCARockford P500-4RF Punch P165-S in doorsRF Punch P165 in rear deckFront doors deadened with DamplifierNextSQ's new HDS208 8" in a T-line whenever it FINALLY COMES OUT I CAN FINALLY AFFORD IT Bend over and I'll show ya. how is it 2 days work? half a day at most, i may be an idiot, but im not an idiot.

drbizerk Posted February 27, 2014 Report Share Posted February 27, 2014 according to the engineers at General Motors a tall, narrow, cathedral port has more velocity than any other configuration......my next project is making a rectangular octaport Link to comment Share on other sites More sharing options...

Yes you can if the slot port does not turn, you will need an different insert for each different tuning so it's not very easy. You have tunable aeros which is what I mean for easy, just adjust on the fly and re-test. Link to comment Share on other sites More sharing options...

Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist? I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.
