My girl wanted some bass with her music so i bought her a Phoenix Gold Ryval 12" sub, nothin fancy it is 150w rms and she listens to Rock and occasional rap.

So here is the details:
Her car is a 1996 Honda Accord Sedan
Since the sub is only 150w rms would it be better for it to be ported?

Specs for Sub:

# Subwoofer Size 12"
# Voice Coil(s) Dual (2 voice coils)
# Impedance 4 ohms
# Peak Power Handling 600 watts
# RMS Power Handling 150 watts
# Woofer Surround UV Treated Foam
# Woofer Composition Paper
# Sealed Box Volume .5 - 1.7 cubic feet
# Ported Box Volume 1.6 - 3.0 cubic feet
# Sensitivity 88 dB
# Frequency Response 25 - 250 Hz
# Xmax (millimeters) 7.7 mm
# Top Mount Depth 5.4"
# Cutout Diameter 11"

The custom box i put together for my sub sounds amazing, makes 1 sub sound like two, but i did not design it, i just cut and glued it together, so i ask this. Would someone please be able to design a nice box for that single 12" that works great with rock and rap, sealed or ported whichever would be best for this situation!

Thanks a million!

Rock and rap is like saying sealed vs ported. There are free box plans here on the forums.

Just say if you need it sealed or ported.

Ah, well what would you recommend for this? sealed or ported?

i was thinking since it was only 150w rms, sealed would be too quiet?

more detailed specs:
VCdia: 2-1/8" *Frequency response: 25-250 Hz *Magnet weight: 40 oz. *Fs: 30 Hz *SPL: 87.5 dB 1W/1m *Vas: 1.83 cu. ft. Qts: 0.60 Xmax: 7.7 mm *Dimensions: A: 12.25", B: 11", C: 5.4".

Not always.

Now will it be as loud as ported? Prolly not.

usually a sub with that low amount of power you can get the most out of it by a big ported box....like 3 cu ft, tuned to 40

Would a 2.5 cuft box ported to 38hz sound good? (3 cuft might be too big for the trunk. ) I want her setup to be SQ not just a bunch of farts.

Terrible advise man.

If your gonna do a ported box, tuned to 35hz or less, IMO.

And 2.5 is the biggest I would go.

My current setup is 2.5 cuft tuned to 29hz and it sounds GREAT but its 500w rms.

Is there any specific frequencies to stay by for good sound with Rock?


Well with your suggestions i think this would do nicely?

2.0 cuft ported at 32hz
