Masongotspl Posted August 3, 2014 Report Posted August 3, 2014 Hello, i am planning to rebuild my sub box for a single Fosgate T2D215. The amp pushing the sub is a sundown SAZ3500D. It will be going in a 03 honda accord sedan. My current box is made exactly to the fosgate (slot ported) specs, and doesn't sound as good as it could. I have heard the t2 in other vehicles with larger enclosures sound so much better, and produce all around better sound with tighter bass. If anyone has an idea of a good box size for the t2, please share. I defiantly want to go ported, but I am not sure what it should be tuned to. I listen to a lot of hip hop, and a lot of classic rock. ANY HELP IS MUCH APPRECIATED! Thanks in advance. Also, I have been wondering about feeding the port through the rear arm rest. I have not seen this done much, anyone have opinions on it?
philrab Posted August 3, 2014 Report Posted August 3, 2014 Have you tried running everything through WinISD to see what effect a larger enclosure would have? It's also hard to listen to the sub in a different vehicle, as all vehicles resonate and absorb frequencies differently. I learned a lot about the concept when I tuned my EQ with a real time analyzer. Saw big valleys in the freq curve for no reason at all, something about the car was just eating them. 2015 Toyota Tacoma Build Thread 2007 Mazda 3; 5000K HID's, Kenwood Excelon KDC-X997, Infinity Reference 6.5 comps in front and coaxials in the rear doors, JL 320.4 four channel, Rab Designs built ported enclosure with an SA12, Kenwood monoblock, Redline Leater shift boot/e-brake boot/center console cover, JBR short shifter/shifter bushings/rear motor mount.

Masongotspl Posted August 4, 2014 Author Report Posted August 4, 2014 I have searched for a enclosure design program for Mac and have had no luck. I guess I will have to download WinISD at work and get paid to design a box. Ha. Thanks for your input. I have been doing mad research and have made up my mind. I will be custom making a band pass box ported into the cabin of the car. Tuned to around 42hz. I cannot wait to post pics!
SMF93 Posted August 4, 2014 Report Posted August 4, 2014 Isn't 42 Hz kind of high tuning ? I was thinking 3-5 cubes tuned at 34 hz

The tuning of bandpass enclosures affects the upper-end roll-off not the low-end extension. The amount of bushels of the sealed portion determines the low-end extension of the response. 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.
