SOURCE: I need to know the enclosure specs for the PSW615

Hello chetdyal,

For a ported enclosure with room for a port, you're going to need a box with about 3.0 CuFt internal volume. Using 3/4" material and outside dimensions, this translates into a box 25"(w)X18"(h)X15"(d) giving you 3.03 CuFt allowing a little volume for the sub and port displacement. For a tuned frequency of 38Hz, you'll need a rectangular port 2"X6" and 4.6" in length. A round or cylindrical port for the same tuning frequency would be 4" in diameter and 4.9" in length. Increasing the port length will lower the tuned frequency.

There's excellent volume and port calculators on The12v.com web site. I'd recommend that you browse some of the "box-building" information before you begin your build. The DIY Subwoofer site also has some great resources.

Keep in mind that a ported enclosure will tend to produce the loudest bass notes very close to the tuned frequency. So tune it higher or lower according to the music you will be playing.

Hope this helps.

What r the parametric specs for the ma audio hk15x2


Fo (Hz) : 29.581 QMS : 3.965 QES : .517 QTS : .457
VAS (liters) : 147.723 REVC (Parallel-Ohms) 1 SPL @ 1 watt/ 1 meter (dB) : 90.6 X-Max Linear peak-peak (mm) 70 LEVC @ 1kHz (mH) : 1.043 Enclosure Volume (Sealed) : minimum 2 cubic feet Fill Required % : 0 3dB down point (-3dB) : 43 maximum sealed: 2.5 cubic feet n fill required: 39 at 3 dB down point Enclosure Volume Ported Vented (cubic feet) : 5.0 Vented to Hz: 35 3dB down point (-3dB Hz) : 28 Square port area Sq/In : 80 Port Length : 13" Power Handling : 2000 Watt RMS & 4000 Watt Max. Make sure to use MDF for the enclosure and use 1 inch thickness and use braces as well. This is a beast of a sub woofer. So give it the proper power it needs and make sure that your box is very solid in construction. If installed correctly and given the right power, this sub woofer is bound to put a smile on your face and rattle your bones. I hit 142dB with only one of these subs and im sure if i gave it more power i could hit the 150dB range. DON'T FORGET TO GIVE IT THE POWER IT DESERVES. Have fun dreamsystems.

Which speker box should i use for alphasonik


If it is an open air sub ( hole with mesh in the center of the magnet) no ports are required, and the box should be sealed on the inside with silicone sealant. If it is a closed air sub ( no hole in the magnet) you need a 50mm port about 120mm long Box size will be 13 inches x 13 inches x 13 inches

Which is the size of the box just for one PSW912 to mount


I used to compete with these subs, and found that for street beat 2.7 cu ft ported tuned at 38 hz was the best for this sub.

If using for max SPL your tuning will be much higher, like around 55 hz. But that all depends on the vehicle.
