These are the best quality for price small full range speakers out there. I put them in folded Voigt pipes I built, and they surprise everyone with the quality and frequency range of their sound. Do make sure you note the exact measurements of the speakers as offered.

Used these for some experimental enclosures and they are almost perfect in every sense. Lack low end response but what the heck does one expect from a 4" full range? I was delighted with the results.
