Should I be able to hear a 4Hz difference in my speakers?


I have just upgraded from a Totem Hawk speaker to a Forest Signature speaker. The Hawk's specs are 32Hz - 21kHz. They have a 5.5 " long throw driver.
The Forests specs are 28Hz - 22kHz with a 6.5" woofer. The Forests are physically bigger too. 
I can hear the treble more clearly and more detail with the Forests but no more bass than with the Hawks. Should I be able to hear more bass with the Forests or is the difference in specs inaudible?

Totem makes a lovely sub ( actually many models )

tell a fretless bass player there is no audible difference between 4 hz..

Beatle - nice reminder to play More Tracy Chapman in these trying times...
Also this is a good time to sharpen your tools and ears - get some test tones - Vandertones is a free download off the Vandersteen website 11 bands of warbletones below 120 HZ, get SPL meter and or some iPad based tools ( studio six digital for example ) or REW running on laptop.... improve, learn, fix setup, work on the room, etc...
Both have small woofers so the bass around 30hz is mostly coming from the ports.  In my experience, larger woofers are capable of higher quality bass at lower frequencies than smaller woofers.  The larger woofers will probably go lower before the bulk of the output transitions to the lower quality bass coming from the port.
Hi traceyc.  If the recording engineer didn't give it to you, you won't hear anything. Only organs (pipe) are going to give you much down that low. One octave below 32 Hz would be 16 Hz; so musically a 28 Hz note would be in the "La - Ti" range on the scale downhill from the 32 Hz note (being the "Do" - of the do-re-mi-so-la-ti-do scale). A subwoofer will help. They are easy to build and the boxes are simple. Check out the DIY sites.
