TeamHirshAudio Posted May 16, 2012 Report Posted May 16, 2012 45s are the way to go but i guess if you need anything else PVC pipe cut down the middle and screwed in is ok..
sundown-e21 Posted May 16, 2012 Report Posted May 16, 2012 45's don't hurt loudness, they help it. The reason is less turbulence, and it makes it more efficient because of it. 1983 Bmw 320i 5 speed 251000 miles on it Sundown SA-12d2 Big 3 Optima 75-25 Jensen hlx600 150x4 amp Hifonics BRZ-1200.1D for sub in a 1.7ft^3 ~33hz ported box Pioneer USB stereo Bass knob integrated into old fading switch (Sneaky) Lowered on H&R sport springs with bilstein sport shocks (2" drop and handles like a dream) Leave him be.

Depends on the application actually. 45's sometimes can actually hurt your score. But OP, you can fill the corner with resin and hold it at an angle until it dries, or take pvc and cut it into 1/4's and glue/screw it in, or take concrete former and cut it into 1/4's and glue/screw it in. I did the third one and put expanding foam behind the curve and glassed and bondo'd over the top.

You never know how strong you are until you cold-cock a woman in the head and break that bitches jaw. Next time she tries to punch you in the stomach, whip your wiener out and chase her around.

TeamHirshAudio Posted May 16, 2012 Report Posted May 16, 2012 45s are definitely the best way to go..
ALPINE408 Posted May 16, 2012 Report Posted May 16, 2012 and how much testing have you guys done with 45's??????????? i tested over 40 boxes with 45's with and without 99% the 45's lost db's that 1 % that helped a total of 2 whole boxes was like .2 tenths Have you ever had your woofers blown?
sundown-e21 Posted May 16, 2012 Report Posted May 16, 2012 you learn something new every day! How would decreased wind resistance affect the loudness in a negative way? more displacement? 1983 Bmw 320i 5 speed 251000 miles on it Sundown SA-12d2 Big 3 Optima 75-25 Jensen hlx600 150x4 amp Hifonics BRZ-1200.1D for sub in a 1.7ft^3 ~33hz ported box Pioneer USB stereo Bass knob integrated into old fading switch (Sneaky) Lowered on H&R sport springs with bilstein sport shocks (2" drop and handles like a dream) Leave him be.

ALPINE408 Posted May 16, 2012 Report Posted May 16, 2012 and where in the world did you here 45's decrease turbulance? have you ever had your box in a wind tunnel or filled it with smoke and watched the air movment dont talk out your ass do you have facts to back this claim of 45's and less turbulance? Have you ever had your woofers blown?
OrionStang Posted May 16, 2012 Report Posted May 16, 2012 I new I would open this and see Alpine spittin' tested FACTS. LOL SMD Super Seller My Feedback Thread
sundown-e21 Posted May 16, 2012 Report Posted May 16, 2012 um, they direct the flow out of the port. They also maintain a constant port width. 1983 Bmw 320i 5 speed 251000 miles on it Sundown SA-12d2 Big 3 Optima 75-25 Jensen hlx600 150x4 amp Hifonics BRZ-1200.1D for sub in a 1.7ft^3 ~33hz ported box Pioneer USB stereo Bass knob integrated into old fading switch (Sneaky) Lowered on H&R sport springs with bilstein sport shocks (2" drop and handles like a dream) Leave him be.
