lowrhadur Posted July 31, 2014 Report Share Posted July 31, 2014 (edited) Just attempted to build and tune my first box. If i did it right.... What folows should assemble a slot ported box that is about 3.0 cu ft tuned at 32hz after displacement. Could someone please double check this for me? DC LvL 3 15" DVC 2ohm powered by a pioneer 8601 at 800watts RMS @ 1ohm 3/4" MFD Outside diameter: 19.5" High x 24.5" Wide x 19.25" Deep Inside diamater: 18" High x 23" Wide x 17" Deep Port: 2.5" Wide x 18" High x 23.75" Long Cutouts: Bottom: 24.5" x 19.25" Top: 24.5" x 19.25" Back: 24.5" x 18" Right & Left side: 18.5" x 18 Front x2 (Doubled): 20.5" x 18" Port (2pc) 14.5" x 18" and 5.25" x 18" Edited July 31, 2014 by lowrhadur Quote Link to comment Share on other sites More sharing options...
Pasta Prime Posted July 31, 2014 Report Share Posted July 31, 2014 Box seems on the small side for that little power but I'm not familiar with what DC recommends for that 15.

This sub is rated at 900RMS and 3.0cu ft ported Edited July 31, 2014 by lowrhadur Quote Link to comment Share on other sites More sharing options...
Weigel21 Posted July 31, 2014 Report Share Posted July 31, 2014 Sub is rated for 900RMS and 3CUFT is what's recommended as well, so... However, the enclosure isn't tuned to 32Hz according to "my" calculations, or should I say Torres, nor is the internal volume exactly 3Cubes. According to Torres, the enclosure is more like 3.09cuft tuned to 36Hz after port and sub displacement. Not sure "I" agree, but that's what I got using Torres. Weather or not such is correct, it seems your amplifier lacks a subsonic filter, so I hope you plan to avoid playing anything with bass below the tuning of the enclsoures, be it 32Hz or 36Hz. Stuff from artists like Young Jeezy could spell disaster for the sub. Also, getting the gain set on the amplifier properly will be key, as the sub is rated to handle more power than that amplifier is rated to do, and I'm not so sure it can even do rated power at 1 ohm, at least not without one hell of an electrical system backing it.

Pasta Prime Posted July 31, 2014 Report Share Posted July 31, 2014 If it was me I'd build a little larger with that little power. Maybe tune to the mid 30's? Quote New build coming........

FocusOn20s Posted July 31, 2014 Report Share Posted July 31, 2014 I had a DC Level 3 15 on 1200 rms in a 3.25cube tuned to 30hz hello lows and hello loud Quote Link to comment Share on other sites More sharing options...
lowrhadur Posted July 31, 2014 Author Report Share Posted July 31, 2014 trying to learn how to design / tune a box. guess im just not getting it. im using the12volt.com and box wizard to play around then sketchup to put it on paper but i guess there is something im not getting Quote Link to comment Share on other sites More sharing options...

How about this. width: 24.5" height: 20.75" depth: 18.5" port width: 2.5" port height: 18.5" port length 1: 15.25" port length 2: 13" total port length: 32.75 Box volume: 3.43cu. ft after port After sub displacement i should be around 3.25cu. and between 31-32hz if this is right. sub firing up, ported to the back Edited July 31, 2014 by lowrhadur Quote Link to comment Share on other sites More sharing options...
