Hey guys i was looking for some input on my box for an RE SXX 10 d2. Running off a hifonics brutus 1200.1 in a Focus ZX3 hatchback. Been messing around with Torres and came up with some numbers. Right now i have a 15x13x32 with 2 4" Aeros at 28 inches in length. Giving me 12.31 port area per foot and im sitting right at 2 Cubes at 32.44 hz. The Displacement of the woofer is .14 and i threw in .1 displacement for bracing and might add some 45 degree corners. My question to you guys is... are 2 28" Aeros too much for this kind of setup? And is 2 cubes net too much for a 10 inch woofer running a little over the rms range (1000)? Specs call for 1.25 cubes at 34 hz. I guess i just want to know if this is going to tear my sub up, and also is it gonna be loud enough? would like to hit 140 is my goal, can also change out aeros if need be for that. Im new to box building and new to anything serious with car audio, any help would be appreciated. Thanks Sub up, port back firing I have the entire thing modeled up to spec in Solidworks please tell me what you think http://www.flickr.co.../in/photostream Is that the best position for the cutout? where the air would travel the longest distance is how i planned it Spacing around the ports okay? I have 5 inches between the wall and the entrance to the port

Alright, I am not expecting much from this setup since it is going in a small car and the box dimensions will be very limited, but i am looking for whatever setups are possible. My current setup is a JBL P1222 in a 2.2 cu box ported at 33 hz and i feel its not enough. My first question : Can i do better with the RE SX15D2 than the jbl P1222? My dimensions for a simple box is 36 in x 16 in x 16 in. But if i make it a more complicated shape i could push out 40x16x16. I am not just fully pushing for spl, but i do wish to have some sound quality. If my current setup with the jbl is 33 hz and there is a little shaking, would tuning the RE SX15 lower to about 25 hz be better? there is a video with a single Kyoki (im pretty sure i misspelled it) sub and he has a moderate hairtrick going. im not out to shake houses or anything I even pull my windows up if im at stoplights, I understand i have a small car and limited working area, but what are the best box designs i can push? the specs seem to be this for the re sx15d2: Electrical Q Value (Qes): 0.38 Mechanical Q Value (Qms): 4.7 Total Speaker Q Value (Qts): 0.38 Free Air Resonance (Fs): 27.8 Hz Equivalent Compliance (Vas): 126.3 liters One-Way, Linear Excursion (Xmax): 22 mm Efficiency (SPL 1W/1m): 90.4 dB SPL Effective Piston Area (Sd): 810 cm2 DC Resistance (Re): 1.9 ohm Nominal Impedance (Znom): Dual 2 ohm Thermal Power Handling (Pe): 1000 W Force Factor (Bl): 21 power is not an issue for 1 sub, but all i have at the moment is the 1 re sx15d2. If the hairtrick is impossible with my setup, what would in turn be the best box, for both loudness and sq? -
alright i have 2 options for what i can do with the box, 1. 3.94 cubic feet @ 32 hz with 3 4" wide areo ports= about 37 inches of port area 2. 3.54 cubit feet @ 34 hz with 4 4" wide aero ports = about 50 inches of port area Can anyone explain pros and cons of either, weaknesses and strengths. SPL or for trying hairtricks? and i can tune the amps subsonic frequency 7 below the box tuning or is it 3?
