new box for L7 12's


Recommended Posts

sooo i dont wanna hear any flamming here im just asking this question about this said box because i can get them for under $70. For the price what do you guys think about this? http://proboxrocks.com/products/unloaded/superbass/212SQSPB/index.shtml Right now im running the prefab kicker box that the l7's come in http://www.ghd24.de/images/product_images/original_images/ds12l7_r-w1000-h600.jpg and im wanting something tuned to be louder and a little lower. I've heard and read from searching these are tuned to around 36-40hz? Im assuming the prefab kicker box is probably tuned around the 45-50's but i cant seem to find an exact answer on that. For under $70 do you guys think the probox is worth it? The actual box price will be closer to probably the $50 range so im thinking its not a bad deal.

It should be an improvement, but of course custom built will be the best option.

I don't think you'll be unhappy coming from that second prefab, tell us how it goes. :)

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.

Do you know what how far back the port goes?

And the sub displacement?

I was going to try and throw it all into torres but need those two things.

Port is T shaped look at the pics...it shares the back wall on both sides and splits to left and right at half with middle port width...so it makes a T shaped..the bottome of the T being the exit of the port.
