Kerfed or squared?

Squared(sharp right angles)tend to make some noise at higher power levels. That makes for port noise that hurts SQ.

Kerfed is a slow rounded edge that helps eliminate port noise period. This is a much better port design period.

Round ports are not worth the trouble IMO.

squared port but im gonna get some pvc or any platic tube big enough to use to round the inside corner of the port so that the port remains the same size all the way through. if you look at the picture of the inside of the box you will see in the port that the corner is rounded.

not going for spl more for daily but a decent score with a daily setup would be nice.

Yes , angles hurt spl from what ive seen , if you want to find "dead" space in your box, add some saw dust in there and bump for a few days, the saw dust will gather where air movement is lacking , adding a 45* to the opposing corner forces air into the "dead area"

thats a good way to test the airmovement in a box that i never thought of doing before.

talked to my good friend at the shop i get my stuff from to get some prices on some of the stuff i still need.
--------------------------- msrp cost total
2 punch pro 6" mid each $90 $72 $144
1 t400.4 list price-------- $440 $296 $296
50feet 16gauge wire----- $45 $15 $15

----------------------------$665 $455 i save 210

so hopefully putting some money towards it on payday, might be able to get most of the wire free. when they have a few extra feet of wire just laying on their work bench they will sometimes just hand it over to me.
next up after this purchase is my new t2d415" gonna get those at their cost and then once i get it all together where gonna spend a few hours getting the eq and everything on the pioneer 80prs i just got setup real good.

then all i will have left is batteries, wood carpet and a whole lot of sound deadener. gonna be able to get dynamat 10% over their cost to so ill be saving a lot of money there.
they sell shuriken i can get a decent deal on but i might go with 2 die hard platinum batteries from sears for just over 200 each and then a smaller shuriken under the hood. waiting on pricing for the shurikens i want since they only just started doing shuriken batteries.

for those who might not know, with using the pioneer deh80prs i will be running active ( no passive crossovers). so everything will be completely controlled by the hu and its built in crossover network.
gives me complete control of the crossover points along with the slope for low, low/mid, mid/high and high crossover points.
