It depends upon your criteria. I'm certain that by strictly objective standards one could arrive at a fairly short list. However, we all know that most will defer to a subjective evaluation. Therefore, I will suggest a very non-audiophile solution. Audition the Radio Shack Lineaum hybrid in the cast alluminum box. They are usually sold at half-price at least once a year. In my area they are on sale now until the end of October. At $75 each with a satisfaction guarantee what can you lose? Good luck.
Best very small Speakers (at any price)?
I'm building a portable system that will fit in a small equipment suitcase. I'm using a 47 labs Gaincard (50w/ch) amp (that has stepped attenuators to eliminate the need for a preamp) and some yet to be named portable cd player. Has anyone heard some very small (maybe 9"x6"x6" or less) speakers that blow you away? thanks
