Subwoofer Frequency Response Question

[echozhaze]

Hello all. I am looking to deck out the audio system in my car, and I'm looking for a bit of advice. Most of the subs in my $50-$125 price range and the 8" size (I want good quality, not super loud) go down to 30 Hz. Is this an acceptable limit? I listen to a lot of electronic music, including trance, drum and bass, and dubstep, and I'm starting to get into some disco. Would it be worth it to spend an extra $50 or $75 for a 25 Hz min? Thanks for the help everyone.

I find that below 30hz tends to be more of a vibration effect than an audible one that enhances the music. I don't think you would lose out much with only 30hz response.

And while it may be true that at your budget, the best deal will be on an 8" sub for best SQ (larger drivers require more material costs and higher shipping costs), don't rule out a 10" sub. It's a myth that 8" subs sound better (see #6 here). You might check Sonicelectronix. They often have good specials on subwoofers.

30hz is definately an acceptable limit, for that price you will not get a +/- 3db response at 25hz. In addition, very few 8 inch subwoofers have a frequency response down to 25hz.
 
You will be missing out on 5hz worth of sub-bass frequencies, especially for some electronic mixes that divulge into this area. Below 20hz, you just get a warm fuzzy feeling in your body

 
Not entirely sure about the myths posted above about subwoofer size, but you need to keep in mind the SPL of your main speakers and your room size when selecting an appropriate sized subwoofer.
 
For the price range stated, you are most likely looking for a "movie" subwoofer as opposed to a musical subwoofer.

Thats good to know!

I know for myself subwoofer speed and tightness are important for music
