Box tuning

I came up with 35hz,well actually 34.99999hz.What freq. are you trying to achieve?

 

Well I used re audio's box calculator and I input a 3/4" thickness for the wood.Is that what you have?

 

I also assumed that the dimm. you gave were outside,are they?

 

Now I get 36hz with the correction.I'm not so sure about this calc.,maybe some other guys can see what they come up with as well.

 

I have a box in my car that was professionally planned out,I built it to his specs and it within a 1/2hz in tuning with the re calc.I'm not saying it's right I'm just saying.That really sucks that your that far off.I've been there and tried other programs but I don't know all of the terms and calculations that need to be done.That is why I left it for a professional.

 

I've had a set of subs powered with the same amp and tried 4 different boxes.I started out with a friend helping and a box tuned to 46hz.I kept tuning lower until I got what I liked.Right now it's close to 32,but my new sub is going to get a new box and lower tuning maybe 29 or so.I've only heard 1 12w7 and it sounded fantastic.

 

Orgasmic.That sucks about the double bass.

 

NO I got it.

 

your wanting sq but are wanting to tune down too 30hz.. thought the lower you tune the deeper and more powerful the bass got(SPL)

 

your right. i want spl so i guess i need to tune hight.

 

With a boxes tuning its all what you want and your resonant freq

If your going spl you tune multiple times to get the highest db reading on the resonant freq. What was your sealed box tuned to that will give you what to tune your box to for your liking.Next thing what does the manufacturer recommend for port area per cube. Also hows your amp adjusted if your subsonic does not match the tuning of the box by exact or ten percent below the boxes tuning the sub will load and unload incorrectly and sound like poop.I use 12volt.com to tune my box it works for me I tune around 35 hertz hits lows and highs.
