55-65hz is not a good crossover point between mids and subs. 80-120hz is a more realistic number for the majority of setups. Risking bottoming out on your speakers when you turn it up is not good. Most subs can play easily up to 120hz with no strain whatsoever.

 

and all the way down to 40hz no problem with even low end subs

 

Thats nothing to brag about. :hs: My box is tuned for 30hz and it will have no problem playing a 20 or 25hz note.

 

Tune lower! Let's hit those low low bass notes that make you throw up.

But back to the point at hand... crossover at about 80hz like b00gers suggested.

 

first I'm talking about sub not box

and how the hell is it going to make you throw up?

 

First, b00gers said his box is tuned low, so his sub can play lower than what you said subs can play down to. This is a direct response to your comment; it's not exactly a tough correlation to understand.

Secondly, low low bass notes in the range of 10hz or so can cause some people to get queezy and want to throw up. (You should learn to phrase questions more politely.)

 

I know that. Subs reproduce frequences, boxes dont. I am just saying that a sub that can go "all the way down to 40hz no problem" is not impressive at all. In fact all subs can do that.


Anyway, at least we can agree that having 2 sets of subs playing a similar frequency range is a bad idea.

 

80hz is a good starting point. It will be within the upper limits of the sub (usually), and in the lower limits of your mids (usually).

Start @ 80hz and tune to your liking... there is no "right way" to tune. It's all preference.

 

thats what I was thinking.

my 12s are cut off at 120hz
