jmilch Posted July 23, 2011 Report Share Posted July 23, 2011 (edited) Sub is in my sig as well as amp, building a new box. Using the torres calc (awesome program btw thanks torres) how low should I shoot for tuning? Going to be going with 4 cu ft, slot ported. According to memphis, they reccomend 38hz for tuning for SPL, but I am not going to be competing. Its just a daily. is 30 hz too low for a newer Cast Mojo Quad 1 ohm 15?

jmilch Posted July 23, 2011 Author Report Share Posted July 23, 2011 I was thinking of shooting for 30 hz. Its in a slightly larger box design that recommended. Anyone else?

6berry Posted July 23, 2011 Report Share Posted July 23, 2011 i normally try to keep tuning around 32-35 hz for music but i know some people like higher and some people go lower. if you want to try some different options then use a pvc or aero port and just cut different lengths and see which sounds best to you Quote 1999 Audi A4 1.8T::: 4 - DC Level 3 10's in a 4th order Rockford P6002 on Subs for now (3-3.5k coming eventually) MB Quart ONX4.60 for Mids and Highs Boston S50 Components in Front Boston S65 Coaxials in Rear 40 Sq Ft of Second Skin Damplifier Build Thread UBL 1948 Plymouth Link to comment Share on other sites More sharing options...

So would 32 be safer for general music listening? Assuming my calculations or the program will be slightly off?

Supercharged DCs Posted July 23, 2011 Report Share Posted July 23, 2011 I'd like to know why it wouldn't be safe. I thought as long as you set your subsonic properly, along with the other amp settings, you would be fine. Quote Bassless once again.

I thought as long as you set your subsonic properly, along with the other amp settings, you would be fine. I set my equipment properly. I meant safe as a play on words, not as in me chancing my equipment. Of course with the subsonic set and gain set proper it will be fine. I am wondering if it will sound like money ass. And don't say "try it and see". I'd like some help, I dont plan on changing the port at this point, when it is in done... So 32 ish?

My system is my daily driver, and my 2 12's are tuned to 32hz, it hits nasty lows, VERY well, and is pretty darn loud on the higher frequencies.

nickfs442 Posted July 23, 2011 Report Share Posted July 23, 2011 Check out my system, not to thread jack. But I have my BTL 15 in a 4 cube box @ ~32 Hz, and it gets lowww. Great daily driver for music, I have about 44 sq inches of port as well. I would say go for 32 and you can always build a new box.

I am using 3/4" birch ply for it. You probably have a trunk area very similar to mine. My only major limitation is my height @ 16" max Quote Pioneer AVH-P4300DVD | Hertz 6.5 | Alpine Type R 6x9 | Custom 200A Alt | Knu Flek 1/0 Big 3 and all wiring | Eclipse EA3422 | AudioQue 2200d | DC XL 12 | Red Oak Box ~2.8 cubes @ 30 hz | Link to comment Share on other sites More sharing options...
