soundsystemaniac Posted November 18, 2011 Report Posted November 18, 2011 Im doing as much research as i possibly can before i build this next box. id like it to be very efficient. but id like to know which is the most efficient type of port between a slot port, aeroport, or a kerf. i know a kerf is a lot of work, but ive got time and patience for it. Can someone please explain the pros and cons of kerf ports and what applications they work best in? If it helps, ive got a vehicle and equipment list: 2007 Jeep Grand Cherokee SRT8 12" AA Mayhem d2 subwoofer AQ2200d amplifier 2 stock batteries all 0 gauge shok wire EDIT: im talking about like a one sided kerf port. not all 4 lol Chevy astro 2 18s and 9k rms Walled!http://www.stevemead...rms-42-inch-tv/JEEP GRAN CHEROKEE SRT8 BUILD!2 JL AUDIO 15s trunk buildDC XL 15 buildDC level 3 18 buildhttp://www.stevemead...verunner-build/ http://www.facebook....hp?id=646651228
AmericanLegend Posted November 18, 2011 Report Posted November 18, 2011 Nope. Nothing currently on the market is more efficient than an aeroport. Also, it will be hard for a port with corners (ie. square, rectuangular, triangular) to be as efficient as a port with no corners (a circle). A kerfed port IS, however, a good bit more efficient than a regular square-edged port.
blownengine Posted November 18, 2011 Report Posted November 18, 2011 They are slightly more efficient than a slot port without one. But even then they are DAMN SEXY and thats why I like them. 2003 Dodge Ram 1500 SLT (Yea its got a Hemi)Alpine CDA-105KnuKonceptz 0ga CCA Big 3 with Yellow Top 15" SoundQubed HDC3DC Audio 1.2K (Bass)Pioneer 6x9's (Front)Pioneer 6.5's (Rear)Kicker 3.5's (Dash)Sony amp on the highs.

STEvil Posted November 19, 2011 Report Posted November 19, 2011 Depends on your kerf job and final port mouth area and expansion rate. If you build it identical to an aero then of course it will be the same efficiency wise.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

STEvil Posted November 19, 2011 Report Posted November 19, 2011 Do what? Its all in the final box design you chose.

AMI CUSTOMS Posted November 19, 2011 Report Posted November 19, 2011 In a kerfed port design, the radius of the kerf can make or break the box. In any box under 10 cubes, I would use aeros for numbers, over 10 cubes, I am doing a slot port and then test with kerf from PVC to see if it helps or hurts. It isn't a one size fits all once you get to a very large box. That last part was just for a why not mention it lol.

A kerfed square or rectanglular port simply cannot be as efficient as a round one because, for a given port area, the square or rectangle will have more internal surface area.
