My first tuned box. Did i do it right?


Recommended Posts

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

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.

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
