Best subwoofer and amp for 4 cb.ft. box

[shayzonblue]

I'm hoping to have them cross around 76-78 hz. The midbass will be baffled in a separate enclosure

I've done the math and 25 hertz would allow my midbass midrange full range and highs to b next emely accurate because I love SQ and SPL perfectly balanced. Also to he honest I drive a car that doesn't have tons of space. Its my family car. Lol

Im running 2 (12's) in 5.5 cubes in a single ca truck bro! Im telling you that tuning will be too low for your choice of music.

What are the enclosure and port dimensions?

Here is my sub and amp setup! 5.5 cubes, 6500 watts pushing 2 12's

25 hertz lol

cabin will extend playable frequency down to around 18 hertz.

you tune to 25 hertz and most likely wont be happy at all

try about 38

So what makes 38hz the magic number for his goals?

There is nothing wrong with tuning low. It usually flattens out the frequency response and lowers group delay. The only drawback is it may cost you a little output vs a higher tune, but for many that's a small price to pay for better overall sound quality. It all depends on what your priorities are, what's right for one person may not be right for another.

My daily driver is tuned to 26 Hz, and I wouldn't have it any other way.

cant this would be "his" magic number but I lsiten to alot of jungle/dubstep/rap. been listening for about 17 years now to jungle with various systems for the last 15 years. (Dieselboy FTW)

and around 38 has been great for my listening purposes. Now i dont lsiten to any slowed music but i dditn see him list any of that in his first post.

it sounds like he wants something to really bang on jungle/dubstep and around 38 shuld be great for that.

For a subwoofer stage tuned to 25hz you will most likely need a woofer stage to play 40hz to 150hz. Then mid bass 150hz and up. I don't think your current mid bass will be able to play low enough to fill the gap especially if the sub stage is ported causing a peak at such a low tuning frequency. I have done a similar setup with two 15s and four 10s but not tuned that low.

Can't find a single 12 for 4 cubes but a DD 9915 would work with 2 M2's hooked up .
