What are the smallest speakers that are clean and flat down to 20hz?

^With those dispersion characteristics, and everything else; is the ideal surround sound speaker?

bdp, a 5-string electric bass will go a fourth (possibly a fifth) lower than 42 (E)--down to B or A (27.5), about the same as a standard piano.

From having recently tuned a piano I can tell you that it's really hard to discern precise frequencies down in that range.

I didn't have time to read all the posts, so I don't know if the conversation evolved into something else. But to answer the original post, the Genesis 500's delivered some of the best bass I've ever had in my listening room. They looked like a Watt/Puppy, and they were about the same size. I'm assuming you are looking for a small floor standing speaker, and not a stand mount.

I used to think that there are no stupid questions; just stupid answers.
After reading this topic I have changed my mind:

                STUPID QUESTIONS DO EXISTS !!!

Why is it stupid?
