gmoxley1 Posted November 30, 2014 Report Share Posted November 30, 2014 So I'm getting a sundown x 15 soon and was trying to come up with a box for it and have a few questions. I was told that they hit lows in smaller enclosures as well as larger ones but tend to lack above 40hz in huge boxes. I have a box planned that before displacements, is right at 4 cubes (4.09) tuned to just above 30 with 58 square inches of port ( I used re box calculator as well as the calculator on the12volt). I'm running it on a SAZ-1200d so just around rated. I'm looking for hard hitting lows with respectable 40-55hz range. So I'm not picky about hitting high notes hard. Does anyone else have any box suggestions or tips or anything? I'm open to suggestions!

SQL50 Posted November 30, 2014 Report Share Posted November 30, 2014 Don't use re, I made that mistake once and built a box off of it's specs. Download Torres and model it up, it gets you close. Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted November 30, 2014 Report Share Posted November 30, 2014 The X-series subs generally have a large peak in output around tuning, this is what makes them kill the lows. If you put them in a box on the smaller side of things it will decrease this peak, making the higher bass notes sound louder relative the low stuff. This does cost you a little bit of low end efficiency, so it depends on what your priorities are.

So what would be considered a small, medium, or large enclosure? 1998 chevy blazer 4 door stock alt 105a Battery: Autocraft Gold 75-3 Big Three in Sky High Car Audio 4ga subs: rockford p2 12's (soon to be sundown SA 12's) Sundown SAZ-1200d on the subs Mids and Highs: Infinity kappa 6.5 mid in front doors and tweets in Dash sae 50.4 for mids and highs SMD OM-1 on the subs Link to comment Share on other sites More sharing options...

I believe these woofers need a minimum of 4.25 cu ft as well. If you're running an SAZ 1200 I'd go atleast 4.25 with a smidge more of port area... Thanks alaskanzx5 I might just do thatI can recone a sub myself. About a year ago I took 2 12" power acoustic mofos and made one sub. I took the magnet and the motor off of one and j b welded it to the other motor and magnet. I had to wind my own voice coil so it would work. After I was done hooked up to 2 boss 5000w amps. And shattered my back and all my side windows came to this thread to recommend soundqubed and ct sounds. OP goes with soundstream. oh lawd.

Triticum Agricolam Posted November 30, 2014 Report Share Posted November 30, 2014 Sundown says the X series can work in as small a box as what the SA series uses so you should be able to go down as far as 3.0 cubic feet net, which is what I would lean more towards, but I like a flatter response and am willing to give up so low end output to get it.

Thanks for the info! Very helpful! My vehicle peaks in the mid 40s so it may help even it out if I go a little over 3 cuft. 1998 chevy blazer 4 door stock alt 105a Battery: Autocraft Gold 75-3 Big Three in Sky High Car Audio 4ga subs: rockford p2 12's (soon to be sundown SA 12's) Sundown SAZ-1200d on the subs Mids and Highs: Infinity kappa 6.5 mid in front doors and tweets in Dash sae 50.4 for mids and highs SMD OM-1 on the subs Link to comment Share on other sites More sharing options...

Wouldn't be bothered to help you but if you want to give it a shot you can still run torres in a mac with virtualization software as virtualbox.
