Just because it says it can produce a 20hz tone doesn't mean it will do it well. Heck, ANY speaker driver, even a tweeter, can produce a 20hz tone, just not well.
Most car subwoofers have a resonant frequency somewhere around 40hz. They are designed to take advantage of a car's cabin gain. If you put a car sub in a home environment you will be missing out on a lot of the really low bass. They do this so they can use smaller boxes in the cars. If the subs had a resonant frequency near 20hz, like a lot of home subs do, then the boxes would be much larger.

Ummmmmm
Ya.
Lets be realistic here. The average Tweeter doesnt have the excursion to produce a wavelength at that frequency. Its physically impossible.
As to the rest. That much is true. However this is a Ported enclosure and that changes things a bit.
I am sure it can do 20hz. The question is how many DB it will be below the rest of the response curve.

There is some good mostly accurate information in this thread. I am a bazooka dealer and thought I would toss out a couple of comments based on 20+ years of experience in the Audio industry designing speakers and speaker cabinets.
Mazeroth is correct that most car subs have resonant frequencies around 40 hz. For a car, your primary purpose would be to listen to music and most music does not have much if any sub-40hz information to reproduce.
Macgyversite is right that ported cabinets change things some what when it comes to lower frequencies, but I think they do not change them in the manner he thinks. They are not some magic hole in the box that mysteriously makes every thing better.
This cabinet is less than 1 ft^3 with a 1"X12" slot port tuned in the 45hz range. This means that any information below 45 hz will cause the woofer in this cabinet to "unload" and act as if it is not in any box. This leads real fast to woofers "thwapping" as the suspension bottoms out and eventually blows the speaker from over-driving it. Can it play a 20hz tone? Yeah, but it won't do it very loud or for very long before it dies. In fact, it would likely have more 20hz information if the cabinet were sealed. Just as an FYI, a slot port this size would need to be 75 inches long in order to tune the cabinet at 20hz which would give it an obnoxious first order port resonance at 82 hz that would destroy any semblance of sound quality
All that said, this box is decent for the price (less than my dealer cost) and would satisfy most non-audiophiles just looking for a little bit more low-end. One thing to note for those folks buying two of them, they are 4 ohm cabinets so make sure whatever amplifier you want to use can handle the appropriate load if you want to bridge or run it in mono. You should be able to run them in stereo with just about any amp.
I got mine before the storm hit.
Great quality for the price.
Will be fun to see what 2 ported 10's sound like compared to 2 RF Punch 8's that are sealed in my sons car.
And Mazeroth. We are not all graduates of "The Audio Design Institute" so misused words or lack of being able to correctly describe what we hear is a problem. We are all not perfect.
Soooooo there is a point that is not valid.
There is AMPLE music with sounds below 40hz. The "E" string on an Electric BASS is 41.2hz roughly. The Piano goes down to 22hz. Sure they dont always use these frequencies but electronics do and they are used a lot in todays music.
Heck my favorite Album has notes below 40hz all over it. 1976's Genesis "Trick of the Tail". Bass Pedals all over that album with 30hz notes used frequently. Rush's Geddy Lee uses bass pedals to augment his playing since they are just a 3 man band.
Nice Tower btw.
